20/7 Burn-In Test
OLED vs LCD VA vs LCD IPS

On August 31 2017, we started a long-term 20/7 burn-in test on 3 TVs (OLED vs VA vs IPS). We aim to see how their performance change over time, especially with some static images such as network logos, black bars in movies, or video games with a fixed interface.

We already test for temporary image retention, which generally subsides over the course of a few minutes. This is more of a temporary annoyance and results in some faint artifacts usually visible in areas of high contrast.

Permanent image retention is a more serious issue, but it requires looking at the TV's performance over the course of months or years. We will be testing 3 TVs side-by-side, the OLED LG B6, the VA Samsung KU6300 and the IPS LG UJ6300 in a year-long test.

Week 44 (07/13/2018): All results have been updated including peak brightness, color gamut, and uniformity photos. The peak brightness and color gamut measurements remain in the same ballpark for all TVs.
Week 42 (06/28/2018): Uniformity photos updated.
Week 40 (06/14/2018): New uniformity photos have been taken for each TV.
Week 38 (05/31/2018): Uniformity photos have been updated.
Week 36 (05/18/2018): All results have been updated including uniformity photos, color gamut measurements and peak brightness measurements. Brightness and color gamut are in the same ballpark. Next uniformity photos update will be 05/31/2018 and next full update is 07/12/2018.
Week 34 (05/04/2018): Uniformity photos have been updated.
Week 32 (04/19/2018): Results updated. The TVs have been mounted on the wall next to the real life OLED burn-in test. The photos appear slightly different, but this doesn't affect the appearance of burn-in.
Week 30 (04/05/2018): Uniformity photos have been updated.
Week 28 (03/23/2018): Peak brightness, color gamut and uniformity photos have all been updated.
Week 26 (03/08/2018): New photos taken. Retention in the IPS TV is becoming apparent.
Week 24 (02/22/2018): Uniformity issues continue to progress.
Week 22 (02/08/2018): Results have been updated.
Week 20 (01/25/2018): Uniformity and color gamut/peak brightness results have been updated. From this point, we will adjust our measurement cadence to match the Real life OLED burn in test. The next uniformity photos will be posted week 22 (02/08/2018) and the next color gamut/peak brightness measurements will be posted week 28 (03/22/2018).
Week 19 (01/18/2018): Results have been updated.
Week 18 (01/11/2018): The uniformity photos have been updated. When looking at the solid logo of the B6, some color shift is noticeable. This may be due to the different rates of sub-pixel degradation.
Update 01/05/2018: We posted a video update discussing the results so far here. Also, we are starting a new concurrent OLED burn-in test with real live content.
Week 17 (12/29/2017): The color gamut and peak brightness have been updated and remain in the same ballpark for all TVs.
Week 16 (12/22/2017): Results updated.
Week 15 (12/14/2017): New results posted.
Week 14 (12/07/2017): Uniformity photos updated.
Week 13 (11/30/2017): No significant changes to brightness or gamut.
Week 12 (11/23/2017): Uniformity photos updated for week 12.
Week 11 (11/16/2017): New results have been posted.
Week 10 (11/09/2017): The results have been updated.
Week 9 (11/02/2017): Screen photos have been taken and the color gamut and peak brightness tests have been performed. Burn-in continues to develop on the B6, however the peak brightness and color gamut remain in the same ballpark.
Week 8 (10/26/2017): The LG UJ6300 has received a firmware update (04.70.03). Retention continues to become more visible on all four corners of the red and magenta slides.
Week 7 (10/19/2017): New screen uniformity photos have been taken. Retention is visible in all 4 logos on the B6.
Week 6 (10/12/2017): The screen uniformity photos have been updated, and the retention issues continue to develop on the B6. Because no changes to peak brightness and color gamut have been observed so far on any TV, the frequency has been reduced to every 4 weeks. As a result, the next peak brightness and color gamut update will be 11/02/2017.
Week 5 (10/05/2017): Image retention continues to develop on the B6. OLED Light/Backlight settings: B6-63, KU6300-7, UJ6300-100.
Week 4 (09/28/2017): Some retention is visible on the LG B6 OLED in purple, red, green and blue slides. OLED Light/Backlight settings: B6-63, KU6300-7, UJ6300-100.
Week 3 (09/21/2017): No significant changes since week 2. OLED Light/Backlight settings: B6-63, KU6300-7, UJ6300-100.
Week 2 (09/14/2017): The B6 has received a firmware update (05.30.03). There are beginning to be signs of permanent image retention at the static logos in each corner. The brightness and color gamut measurements are all within measurement variance. OLED Light/Backlight settings: B6-63, KU6300-7, UJ6300-100.
Update 09/01/2017: As a result of feedback from readers, we have updated the methodology to turn all TVs off for 4 hours per day, and have included a yellow 'I' in the Rtings logo.

Test Setup

 Burn-In Test Setup

The TVs are placed side-by-side in one of our testing rooms as shown to the right. The TVs will stay on for 20 hours per day, 7 days per week, running our test pattern in a loop. They will be turned off for 4 hours each day using USB infrared transmitters connected to each TV and controlled by a PC to better represent normal (but still very heavy) usage. Calibration settings have been applied, with the backlight or OLED light set to produce 175 nits on our checkerboard pattern. On the B6, the 'Pixel Shift' option is enabled.  A single Android TV Box is used as a source, with a HDMI splitter used to provide the same material to each display.

The Pattern

 Burn-In Test Pattern

A 5.5 hour video loop is used as the test pattern. It has been designed to mix static content with moving images to represent some typical content. The base material is a recording of over the air antenna TV with RTINGS overlay logos of different opacities and durations, and letterbox black bars added. These additional elements are:

  • Top and bottom: Letterbox bars present for 2 hours, then absent for 3.5 hours (movie example)
  • Top left: 100% solid logo, present for the whole clip (torture test)
  • Top right: 50% opacity logo, present for the whole clip (network logo torture test)
  • Bottom left: 100% solid logo, present for 2 hours then absent for 3.5 hours (video games example)
  • Bottom right: 50% opacity logo, present for 10 minutes then absent for 2 minutes (sports or TV shows example)

Weekly Updates

Each week we will perform the following procedure

Limitations of the test

  • Small sample size, so it won't show the variance between units of the same technology
  • Extreme case, where TVs are running 20 hours a day with the same 5.5 hours loop. You will get a better lifespan at home if you use the TV less and with more varied content.

Conclusion

The goal of this test is to get more information on the burn-in issue on TVs and how it affects their lifespan. We will have more information in the next few months on how it should impact your buying decisions.

It is a shame your logos don't have any yellow or orange! These seem to be the greatest offenders besides red that will cause burn in on the LG Oled displays. It would be highly recommended you implement any additional yellow or orange logos in your test too check for burn in or severe IR. According to a pol at avsforum the 2016 Oled's are currently at a 16% burn in rate. You need to see this thread as well. www.avsforum.com/forum/40-oled-technology-flat-panels-general/2804065-oled-screen-burn-photos.html
Thank you for contacting us. We've updated our test pattern to include some yellow.

Awesome test and great site!

Attached is a picture showing burn-in on my OLED 65" B6 Series LG that I just noticed this weekend. I purchased it from PC Richard and Son in Nov/2016 (not even a year) with an extended service warranty.

Tried the Clear Panel Noise to no avail, and have Screen Shift enabled as well.

We use this TV simply for watching movies and shows, nothing "abnormal". Tough to see from the image because of the words, but the entire center area seems to "burned" as well. Going to call PC Richard tomorrow and see what happens.

This seems to be a failure of the OLED pixel - or a degradation where the OLED is defective and can no longer produce the proper color and/or intensity required for a uniform picture/color. The distinction should be made clear and this should not happen on a product that has been used for less than a year, let alone 3 or 4 under normal use. Manufacturers put the blame on consumers and label it as abuse, which is preposterous. This is an outright product defect/flaw. We should not have to spend thousands of dollars on and then have to babysit electronic products to the point where one can literally not use or enjoy them. In my case the set has been used for nothing more than casual television viewing, and as you can see, it has failed.

Thank you for sharing this image with us.

Update 11/30/2017: The original poster gave us an update on is ongoing issues saying that "both PC Richard and Son and LG both refused to cover my set under warranty. Their argument is that it is burn-in and obviously this means that their assessment/conclusion is that it is my fault. So apparently, I broke my TV by using it as I normally should."

Nice idea. It's been a topic on many sites, especially when it comes to gaming. Not so much when watching movies but again if someone is a cable news nut. One thing. I don't understand how we will interpret the graphs as it concerns to"image retention". The graphs look more like a brightness stability/longevity test than images that remain. How do we understand the relationship of the graphs to image retention? Thanks.
Burn-in on OLEDs unlike Plasma or CRT TVs is not caused by retention or stuck pixels, but instead due to cumulative degradation of the material through usage. This means that over time, OLED TVs will lose brightness across the whole screen progressively. Burn-in is simply a high contrast region of the screen where there was more usage than the surrounding area creating a visible shape. To see the burning-in of the shapes, we'll be taking pictures periodically and will post them on the article.

Hi guys,

I love reading your website, and I admire your passion for even small details. I use your website as a cornerstone when selling tellys where I work. My problem is, I bought an LG C6, and I can see burn in, like an LG logo, and the palm trees which is the standard background picture for the LG TVs. I've tried the clear panel noise feature at least 5 times, but it does not have an effect. I love the TV, and it was the very last one of it, it was a shop display, and I don't want to get a refund as I want to keep the telly. Is there any way I can fix this burn in?

Thanks so much guys, I really appreciate your help!

Unfortunately it is unlikely that it is possible to fix the burn-in on your display. Your best option may be to display normal varied content for a while, and after some time (it may be months) the display may wear evenly so the burn-in is less noticeable. We hope to investigate this more in the coming months.

This will be an awesome test in terms of the panel integrity and if they can withstand the struggle they will be going through! However, the only premium tv on here is the OLED. im surprised you haven't included the Q7 from Samsung in this test, or even an MU8 or 9. Would be cool if there were anything to happen to tvs that can produce an expanded color spectrum.
Thanks for contacting us. The main idea of our test was to test the different panel technologies (VA, IPS, and OLED) and as such, the price of the TV themselves did not play a role in the selection. But it is true that right now OLED TVs goes for a premium price, but this is mainly because the technology is newer and the manufacturing price are higher than let say VA or IPS. And on a side note, the main technology that is being used in the Q7, MU or KU series is basically the same, even though Samsung is trying to make it sound much different than what it is in reality.

Thanks for this test! My 2016 OLED65E6P has a noticeable permanent image of an NBC logo and the word "Live" from staying on MSNBC. I have Screen Shift enabled, and use Clear Panel Noise but it doesn't help.

Email response from LG: To give you a heads up, burn in is not covered by our manufacture warranty and repair services may incur service fees. Although coverage may not be provided, LG will stand behind the product by means of extending assistance in ensuring that repair services may be provided. In this regard, we recommend to also check LG authorized service centers in your area.

Thank you for the pictures. It is unfortunate that LG does not cover these issues under its warranty as they can appear with a normal use of the TV.

Hi, why not do the burn-in test on a newer model OLED since they say they "fixed" / "improved" the problem?
Thank you for your question. Unfortunately, our resources are limited and we couldn't justify the costs of buying an additional LG C7 for this test (we still require our review unit for the rest of the year). While it is true that more modern models might have some features to slow-down image retention and reduce the speed at which it happens, it is our understanding that aging is an inherent limitation of OLED technology that to this day has not been completely solved.
18
I love that you are doing this burn-in test! It's something I've wondered about for some time. It looks like the OLED is struggling already, so why do you recommend the top TV for gaming to be OLED? If you are doing a ton of gaming, you will likely end up with burn-in, no?
While it is true that completely static UI elements found in some games might cause an issue over time, it would require hundreds of hours playing the same game for a relatively minute burn-in of the shape to appear (and games where the UI uses less saturated colors should take a longer time), but without actually being visible in use. Since the effect is cumulative, it is definitely possible for this to happen after months of playing the same game, but we expect this to not be a problem for most people. Users that often leave their TV on most of the day with a news channel playing in the background are a more likely candidate for permanent retention than most gamers in our opinion. However, OLEDs do also suffer from temporary retention which can definitely appear with most normal gaming usage.
15
I really like this ongoing test. It would be nice if you could give a short statement on your findings/noticeable changes week to week. I'm viewing on a mobile phone, so it's hard for me to notice any changes.
We will from now on, thanks for the tip!

First, your website is fantastic. I'm liking the improvements that you guys are making and you have became my first and only site I come to check out televisions.

I've been looking to purchase the LG C7, but using my TV for gaming I'm scared that I will get a health bar or a video game logo burned into my TV. Do you have any suggestions on the amount of time someone should play a game before switching to something else that doesn't have the static image? And also on your 9/14 update there was a mention of permanent image retention. Will you be providing photos of this? Thanks and keep up the great work.

Thank you, glad to hear you find the site helpful!

There's not really a breakpoint for how long you can play before it's best to switch to something else. We have had one user send us pictures of a game HUD burned in on his screen, but many other gamers happily use their OLEDs without issue. We'll know more though as the burn-in test progresses. In particular it will be very interesting to see if our solid pattern that disappears every few hours takes more total on-screen hours to burn in than our solid image that's on screen constantly. This will answer whether there will be less burn-in if you space out your game time or do it all in one go.

We post all seven of our photos every week, though sometimes things are more noticeable in person. Burn-in will likely be most visible on the red slide photo.

I was worried about burn-in on my LG B7 OLED TV when watching PBS news for an hour -- and now when watching I use the "magnify" feature of TV to effectively "miss" the stationary bright white PBS News Hour logo entirely. Better safe than sorry....
Clever idea, that would definitely reduce the chance of burn-in. However if you only watch the news for an hour or two a day then burn-in likely won't be a concern, it's more if you watch 4+ hours of news a day. Also a white logo is less likely to burn in than a colored logo, as we've seen very little burn-in with our white slide photos.

It's great that you are making this test and also that you have modified to add yellow and cycle off for 4 hours per day. I also understand you intend to recalibrate to 130 cd/m2 weekly, which will be a nice way to monitor subpixel aging (more aging = higher OLED Light). You might consider adding a full 8-color rainbow accross the center of the panel - measurable rectangles of White, Black, Red, Green, Blue, Yellow, Magenta, Cyan. This would allow you to measure how quickly each of the RGBW subpixels age when different colors are displayed. 100% White measured in the 'Black' rectangle shoul age the least (hopefully not at all); 100% Red measured in the 'Yellow' rectangle should age the most (according to AVS reports) and 100% White measured in the 'White' rectangle should age somewhere between those two extremes (because the white subpixels are ~3 times more efficient that the colored subpixels as they have no color filter). If you use the White rectangle to recalibrate OLED Light every week, 100% White within the Black rectangle should start creeping up over 130 cd/m2 (or whatever your calibration target is). Appreciate this effort and looking forward to the results!
Thank you for your great question. Unfortunately, due to our limited resources, we had to limit ourselves to a test that was most applicable to a standard use case. Your proposition is definitely interesting, and it would provide a lot of data about the durability of LG OLEDs, but it would significantly increase the resources required for the test which isn't really feasible for us right now. It however is possible that we execute a similar test sometime in the future. As a small correction, our luminance target is actually 175 cd/m2.

I have an LG B7A OLED TV. As I read through these questions, it seems like most of them are from people who do a lot of gaming, and so are engaging in TV usage that might be more likely to cause burn-in than an "average" TV viewer (which I would consider myself to be). I watch TV for 2-3 hours a day, maximum, typically the evening news and then a movie or so. And then I turn the TV power strip off. Is "my" kind of TV usage ever really likely to incur burn-in? In other words, is OLED burn-in an issue that someone with my TV habits needs to worry about? If it is, what should I do to prevent it? For example, should I avoid OLED Light settings of 100%, which is the default for modes like HDR? Should I magnify the screen to "miss" news logos that stay in one place continuously? Should I keep power supplied to the TV overnight so it can perform its anti-burn-in preventive/corrective actions? (My normal practice is to turn all electricity to the TV set and my other AV equipment off when not in use.) Any practical suggestions would be greatly appreciated, as I intend this expensive and wonderful TV to last me a decade.
Leave the TV powered at all times so it can do its screen clearing routines, but otherwise your usage shouldn't have a problem with burn in. Most cases are from people who leave the news on in the background for 4+ hours every day, or play the same game for 4+ hours every day for a year, and even in these cases the TV isn't guaranteed to burn in. If it's to last a decade and if you want to be on the safe side, using screen magnification to miss the news logo may help but it may not be necessary. Turning OLED Light down for SDR will slow burn-in but again likely won't be necessary. OLED Light being at 100% for HDR isn't a concern because only bright highlights will ever use that high brightness; most of an HDR scene is hard-coded for 100 cd/m² APL and is designed to be shown at 100% OLED Light / backlight.

I noticed that Samsung is using a promo that will repair or replace the QN55Q75FM if it suffers from burn-in. Is it just me or is Samsung trying to suggest that this regular LED TV is a OLED. I was almost taken in by the similar product terms like QLED versus OLED versus XLED versus? Thanks for providing so much information in one place. Without you, I would have bought the Samsung model thinking it was an OLED. It’s a good LED model, but it’s not what I am looking for. For truth in advertising, do LED televisions suffer from burn-in? If so, on what scale? My gut reaction is that Samsung is using similar terms in order to sell an updated LED TV, but not an OLED TV. They seem like the only company that didn’t release an OLED this year. Thanks rings.com for keeping our eyes open.
It's unlikely Samsung is trying to make people believe the QN55Q75FM is an OLED by advertising replacement in case of burn-in, but they may be trying to woo customers who are concerned about burn-in. It is possible for an LED TV to have burn in but it's very rare.
Samsung doesn't sell OLEDs, instead they're fast tracking development of their new electro-emissive quantum dot technology, which will likely be superior to OLED.
QLED and XLED are just marketing names: QLEDs are LED TVs with quantum dots in their backlighting to widen their color gamut, and XLED is Vizio's term that is mostly meant to advertise their 'Xtreme Black Engine Pro' full-array local dimming.

I cannot believe so many people are still considering OLED TVs after seeing this test. I was hopeful that OLED would finally allow me to upgrade my 10 year old plasma, but these results are pretty scary. Do you feel the burn in happens quicker than plasma? My TV has image retention which I find a minor annoyance but hasn't exhibited defined burn in like in your results. You will see vague shapes when looking at color patterns, particularly in the lower right corner due to logos. But it's 10 years old, I feel I've gotten my money's worth. If that happened after a few weeks, or even the first year I'd be pissed.
The main thing to consider about this burn-in test is that it's an accelerated torture test, meant to show multiple year's worth of burn-in in just a single year of testing. During normal usage we don't expect burn-in to be noticeable within 5 years, the test is more to determine how fast burn-in will happen in certain worst case scenarios like heavy news watching or playing a single video game for years. We'll know more as the test goes on, and we've started a new burn-in test on six C7s playing more realistic content, you can read more about it here.

About plasmas, their susceptibility to burn-in varied quite significantly from brand to brand and year to year; some burned in very fast, while others like yours barely burned-in at all; but in general the burn-in of OLEDs should be roughly comparable to the average plasma. If your plasma lasted this long then your usage habits seem to be low risk for burn-in, so you may be able to use an OLED for ten years without noticing much burn-in; but if you're not willing to take the risk then an LED TV with good local dimming may be best, like the Sony X930E.

Hello, I have an LG C7P 65" and I am worried about the contrast setting; if I set the contrast to 98 does that mean the TV is more susceptible to burn in or would the OLED light need to be maxed out?
Raise the 'Contrast' to '100', it'll only make the picture a little brighter and will hardly affect burn-in. 'OLED Light' has a much greater effect on burn-in because it makes the TV much brighter, but at normal brightness levels burn-in shouldn't be an issue for most use cases.

I've read in online forums that the reason the OLED got burn-in is because you run it for 20 hours a day and because of that, the compensation cycles don't run frequently enough to clear up the burn-in. Do you think that if the logos were on screen for only a few hours a day and other content mixed in for a few hours a day, and the TV ran for only 6-8 hours a day, that burn-in would still happen eventually?
Yes, burn in will still happen, though much slower than our 20-hours-a-day accelerated test. We contacted LG directly and asked if a 5 hours on, 1 hour off cycle will burn in less than our current 20 hours on, 4 hours off, and LG said there would be no difference in burn in. We run the TVs for 20 hours every day so that we can see results sooner, and we're confident that burn in is mostly determined by the total number of on-screen hours, and is less affected by whether those hours are spread out over months or years.

I've used TV screens as a computer monitor forever and burn in has always been a huge pain. A lot of times things like game UI's will be left up for numerous hours. I ended up going with the KU6300 as my last upgrade but I'm noticing some pretty big burn in after a couple of weeks playing various games. It goes away over time but it's very noticeable for things like wallpapers or UI elements. Any recommendations? I did check the settings to what were recommended here.
This is strange, we rarely ever find any temporary image retention on TVs with VA panels; this year our first X900E unit had bad retention but we consider this a rare case. Your KU6300 unit may be one of those rare cases, if you can still exchange it for a new one then that would be best. Otherwise, the best way to mitigate temporary retention is to vary what's shown on the screen so static sections aren't on screen for a long time.

I have the LG C6 oled and after 8 months of heavy usage I am noticing a vertical bar that runs from the top of the panel to the bottom of the panel that is roughly 3-4" wide and just off-center to the right a bit that appears to be brighter than the rest of the panel. It's not a big issue when watching movies and television but it's an eye sore when playing games because it's usually right where my character is, and in any game that is super bright this bar becomes easier to notice. Any ideas as to what could be causing this? I have tried clear panel noise and various stages of use.
This likely isn't burn-in, it sounds like a problem with the system that drives the pixels. Because it's not burn-in it may be covered under warranty.
8
Did you do the break in for 100-150 hours before the test?
No, our B6 had 86 hours of screen on time before we started the test, but that was from our initial testing and occasional retesting over the past year. The KU6300 probably had similar screen on time, while the UJ6300 likely had a little less because it's newer.

Hi! Thanks for your TV researches. I have some questions about LG long-term testing settings (not-OLED types of TV's are stable strong and not so alarming). Can you share starting values of OLED/Brightness/Contrast settings of LG (for your 175 nits checkerboard light target). Do you change that settings after time to gain a constant 175 cd/m²? Looks like you're used widescreen sample with black regions on top/bottom sides... They're OK on OLED - same brightness as center part. Does it mean that absolutely no "damage" has been noticed after all this time on gently working central screen regions?
On the B6: OLED Light 63, Contrast 100, Brightness 50. UJ6300: Backlight 100. KU6300: Backlight 7.
We will change the settings over time to maintain 175 cd/m², but we haven't noticed any brightness change in the center of the screen yet, as shown by our brightness tests. The only degradation we've noticed so far is that the logos have burned in on the B6; no brightness, color gamut or other uniformity issues have been seen. Our pattern has black bars only one third of the time, and it hasn't made a difference to uniformity.

I have been reading your forum on OLED Image retention / Burn in and I have a question. Several years ago when I bought a plasma TV I ran a 100 hour burn in cycle before calibration and normal viewing use, and have not had a single issue with image retention and/or burn in using it for both TV and gaming (anywhere from 4-8 hours at time). Would running a 100 hour break in cycle potentially eliminate the LG OLED image retention/burn in issues?
Unfortunately this is very unlikely for an OLED. One of the logos on our test clip is on the screen for less than half the time, so multiple hundred hours of normal video has played on that area, but it still has both permanent and temporary image retention. As well the center of the screen has had over a thousand hours of normal content played on it, yet it still has temporary retention when we do our measurements. Some plasmas had more image retention than others, so yours is likely one of the better ones.

I have an LG C7 55". How often should the pixel refresher be used? Also, the stock OLED light setting for game mode HDR is 100 and turning it down makes some games way to dim. Is having the OLED light that high a bad thing?
Hi and thanks for contacting us. Pixel refresher should be run if you notice retention or any uniformity issues. For most people, this will probably be once every few weeks at the most, and LG did confirm to us that is should not affect the lifetime of the TV itself. For OLED light at 100 when the TV is in HDR, it is not as bad as 100 OLED light in SDR since when in SDR, OLED light at 100 will raise the luminance of the TV to the maximum, and everything on screen is going to be brighter. When in HDR, the content is mastered in a different way than SDR, and even if you put the OLED light to maximum, the overall screen luminance won't be at the maximum, but only the small highlights (it could be a sun in the sky, an explosion or just a specular highlight from the reflection on a shiny surface). The problem with HDR games is that there are not all mastered the same way, and some games do look darker than other. In those occasions, you can turn on 'Dynamic contrast' for games that are a bit too dark and it should help considerably.

I have been reading a lot about burn-in and image retention for 2017 OLEDs. I watch cable news for 3-4 hours a day and am concerned an OLED TV may not be my best option despite the great picture quality. What are your top recommendations for an OLED alternative?
The Sony X930E is a great alternative to the OLEDs because of its good local dimming and well rounded performance. It also gets much brighter than the OLEDs, which is good for a bright room. The Sony X900E is a good cheaper alternative that's almost as good as the X930E. If you will often be watching in a bright room with a lot of reflections on the screen, the Samsung MU9000 may be best because of its great anti-reflective coating, though it's not as good in a dark room as the Sonys.

From the Sony X900E review, "The Sony X900E has some image retention, which is pretty unusual for a TV with a VA panel. The retention is really faint and not as strong has seen on some IPS TVs." I think this would be a great TV to add to your testing because of its measured results.
The models in the burn in test were chosen because they had average behavior for TVs of their type, so the results measured on them can be considered fairly accurate for any TV of their type. Because the X900E is an unusual case, any results we measure will only be accurate for it and similar unusual VA TVs.

The primary uses for my TV are watching movies and playing video games. Video games often have a static HUD somewhere on the screen which would be similar to the RTINGS logos you are using for this test. This test is running 20 hrs a day, 7 days a week (140 hrs a week). If I used my OLED TV for an average of 28 hrs a week, would it be fair to say 5 weeks of usage with my TV should show similar results of wear with your LG B6's in one week? If not, what would be a fair comparison or real-world benchmark?
Unfortunately since our test is a lot more intense than normal usage, because we want to see results more quickly, it's likely that our TVs will show burn-in after fewer total hours than a TV used for four hours a day. As such our test can be considered a worst case for burn-in, and most TVs will take longer to shown burn-in than ours. How much longer we unfortunately can't say.

If the brightness of the OLED makes a difference with burn-in, then it seems to me that users of the latest Apple TV 4K should be concerned considering that it keeps the HDR function on at all times, which means OLED brightness is always at its maximum.
While the setting itself is at maximum while in HDR mode, the brightness level of what is being displayed is not necessarily at maximum level. The HDR signal includes absolute brightness levels (i.e. this full red should be at 100 nits) in addition to basic color information, so the brightness of the interface depends on the brightness level Apple picks for each of the elements being displayed. If done properly, the SDR and HDR signal should look identical and therefore not cause faster degradation than other devices.

Hi, I just purchased the C7P and I watch a lot of sports; NHL, NFL and MLB. Two concerns: one is will I have a burn in issue with the logos or scrolling on the bottom of every NFL game considering games are 3+ hours each, and 2nd is how well will this TV display NHL games with primarily white screens? Thank you!
Because the scoreboards are different for different sports, and the network logos are translucent, you likely won't notice burn-in for three years at three hours a day of sports usage. Past three years it's hard to say. You will likely notice temporary image retention after every game, but this will go away after ~10 mins of watching something else.

About the NHL brightness, I just watched some NHL clips on the B7A and it was fairly bright even for our bright testing room; the ABL didn't dim the TV very much even with the screen being mostly white ice. It won't be as bright as some other TVs like the Sony X930E, but most people will be pleased with the OLED's brightness.

Thanks for your testing! I see the B6 has some pretty bad logo retention. Do you folks think the LG C7, or B7A, or for that matter, even the Sony 930e would have less burn in? Thanks.
We believe that the C7 and B7A are just as susceptible to burn-in as the B6; however keep in mind that our test is an accelerated torture test, and it's too early to draw conclusions as to whether the B6's burn-in susceptibility is a concern during normal usage. We're also soon starting a new burn-in test on six C7 units, you can read more about it here. The Sony X930E on the other hand is very unlikely to have burn-in over its lifetime, because it's an LED TV with a VA panel.

I think rtings.com along with every publication should remove any recommendation for the OLED TV's as a gamer device. Any gamer that looks to beat a game will burn their TV with just a few games. Look at the average time to beat a game here, https://www.howlongtobeat.com/game.php?id=1464 Then there are MMOs that REQUIRE lots of time and dedication in their virtual worlds along with their monthly subscriptions. To recommend OLED to gamers is irresponsible especially when the evidence is as clear, or burned-in, as day.
For burn-in to appear, the UI of the game needs to be in the same specific position, and the risk is drastically affected by the brightness of the static UI elements. Games will seldom use fully saturated colors for their interface, limiting the risk for burn-in. Since different games will have different HUDs of different colors and in different positions, the cumulative effect across titles will be insignificant, even for those that play lots of single player games (considering a normal playthrough of 5 to 50 hours) or a variety of multiplayer games. It is true however that gamers dedicated to a small set of (or single) games are at a higher risk, especially multiplayer games where it is not abnormal to dedicate hundreds of hours to over the course of a few years. We will adjust our articles when recommending OLED TVs to inform users about the risks associated with these types of usages. It is however important to note that burn-in still takes a few hundred hours for these static UI elements to be measurable, and considerably more time for these to be perceivable during actual use, further narrowing the subset of people at risk of encountering these problems.

Would be great if you did a follow up test to this one showing what happens to the burn in if you switch up your viewing and remove the all of the logos...maybe the existing burn in will fade with time? I have a 2017 OLED and use it only for Apple TV and am concerned 1-2 years from now burn in is inevitable.
Also, love your site!
Thank you!
We're fairly confident that the burn in is permanent because the subpixels themselves have aged and lost brightness. At the end of the test we may try a 100 hour retention clearing pattern but we doubt it'll do anything. Also you shouldn't experience burn in after two years unless your use is an extreme case like leaving the news on for hours every day. We'll be able to make a more educated statement when the test has run for a few more months, as we see the effects of brightness and color loss over time.

I have an LG C7 and I am using a brightness setting of 54, will raising the brightness setting contribute to burn-in? Also my OLED light setting is 32.
Raising the 'Brightness' setting will have a tiny effect on burn-in, but raising the 'OLED Light' will have a larger effect. We don't recommend raising the 'Brightness' setting above its default 50 as this will ruin the perfect blacks that make OLED so great; the 'OLED Light' setting is the one intended to make the TV brighter and darker, which is why it affects burn-in.
6
Will an extended warranty such as CPS or Squaretrade cover burn-in
Unfortunately, it seems like Squaretrade and CPS's terms and conditions confirm that their warranty does not cover burn-in.

It may be useful for the test pattern to include some black side-bars (to show the effect of displaying old 4:3 content). Some of the burn-in seen may be due to stress on the row & column addressing transistors (as opposed to the pixel transistors, etc.), and there may be a difference in the row vs column transistors that would not show up in the top/bottom side-bars.
While true that it would be interesting, due to the burn-in of OLEDs being almost entirely due to the aging of emissive components in the OLED which reduces its brightness output (looking at sub-pixels through a microscope, we should notice a few "holes" that form where parts of the OLED stop emitting light), we expect letterboxes to be representative enough to draw a conclusion of what it would look like with pillarboxes. It is true that uneven TFT output can cause issues, but these are most apparent during manufacturing and less prone to degradation over time.

Looking forward to the results of this long term test. I was wondering if you felt that there may be a use for taking a picture of the set's in the "off" setting. Some image retention/burn in can be seen when the set is off. As a matter of fact, some cases are more pronounced when the set is off. I know that I would be more irked if I saw an "after-image" when a set was off more so then when it was on because the brightness of an "on" set would blur/conceal/mask the after image. Please consider if you also feel that it may prove valuable. Thanx.
We don't expect the burn-in to be visible when the TV is off on these TVs due to the nature of how it appears on LCD and OLED TVs. On OLED most specifically, it is due to the pixels in a specific region outputting less light than those surrounding, creating a visible shape due to the contrast.
5
If this OLED burn-in is being caused by uneven wear of pixels, wouldn't that imply that if pixels become uneven in wear so quickly, then image quality is going to degrade relatively fast on OLED sets if pixels age so quickly.
The TV includes a few compensation algorithms that act in the background while the TV is shut off to help maintain the panel uniformity over time. Except for a gradual reduction in brightness, we expect this to be less of an issue with time than permanent retention caused by extended playback of static images using maximum saturation levels.

This is Awesome! I mean the testing, not burn in. Thank you all for doing this. I've seen a lot of opinion based videos and articles about the burn in issue with OLED and this is what I need to help make a decision. I was going to buy the C7 tomorrow and found this video this morning. Maybe I'll wait to see some more results. Also just a quick comment, I've heard the 7 series can deal with burn in better than the 6 series. I hope this is true. Either way, keep up the good work, and thank you
Thank you for your comments. According to LG, the 7 series has updated mitigation algorithms that allow it to detect static elements better and should have less risk of retention with real usage. The display panel itself however is supposed to be the same or almost identical, so the physical limitations are the same. We're going to start a new test soon using a set of 6 LG C7s displaying a variety of real content such as live CNN and sports channels. You can learn more about it here.

I just purchased an LG B7A 65 inch and so far l have not noticed any burn in but that is not to say that I am not concerned. My question is with normal use,3 to 5 hours a day with no gaming, how many months/years would it be before I noticed any kind of screen denigration and or burn in? Would you recommend that I return it for a Sony X930E or should I roll the dice on the B7?
If your usage is varied (watching different channels, different types of content) and has few static elements such as logos and layouts found on continuous news channels, it is likely that you will never see burn-in as specific shapes won't be shown on-screen for a very long time. Now obviously, your mileage may vary. News and sports channel are still fine to watch, but people whose consumption is centered around this type of content are the ones that are most at risk of encountering permanent image retention. If you spend most of your time watching series, movies or other types of variety TV, the risk is significantly reduced

Can you please publish the basic Brightness/Contrast/OLED-Light (or equivalent) settings as you recalibrate each week? It would also be great if you could take a reading from within the 100%/100% Top Left pattern from some semi-consistent point (100% red if there is a big-enough spot, perhaps centered on the top part of the white 'R' if there is not). While your weekly recalibration is presumably going to be using the center of the screen where pseudo-random content is displayed, readings from anywhere within the Top Left logo would provide some quantitative measure of the degree of accelerated aging associated with bright static (non-random) content... A weekly 100% white measurement from within the black letterbox bars would also be interesting (even if impossible to do without engaging ABL) - in theory, the black letterbox bars should age more slowly than the rest of the screen and so 100% white measurements should slowly increase as you recalibrate week-by-week...
Thank you for your request. We've started adding the current backlight setting in our weekly updates at the top of the article. Since our weekly measurement procedure already takes about 4 hours, we'll do a more extensive set of measurements about every quarter or so. Both of these measurements would bring interesting data, so we'll try to include them in our more extensive analysis procedure.

I can already see some permanent image retention in the purple uniformity slide from the week 1 tests, in the top right corner. The 'R' of the Rtings logo is already visible to me. Looks like by week 2, you can notice on the red slide as well, and more prominently in the purple slide. I play a lot of video games, and am looking to jump in to OLED. Currently, the B6/B7 are your highest rated and most recommended TV for video games. However, it looks like permanent image retention is a very real issue for OLED, especially regarding static elements, of which most video games have (Health bars, Ammo, etc.). Will OLED continue to be recommended for gaming, given these permanent image retention problems?
Yes, there is what appears to be permanent retention on the logos in the corners. For the time being, we will still recommend OLEDs for gaming as they still offer a clear performance advantage over LCDs due to their instant response time and exceptional picture quality. We will still make sure advise our readers about their durability limitations which can cause these issues. At the current state of our test, we consider this retention to be minor since it will seldom be seen with normal usage and it requires having the same static content on-screen for hundreds of hours for it to appear.

I'm curious if the OLED Light setting for the B6 has any impact on image retention/burn in. In other words, if the OLED Light is at maximum brightness, does this have any impact on image retention?
OLED light makes a massive difference to burn-in; when the OLEDs are brighter they burn in faster. To account for this we set all three TVs to the same brightness of 175 cd/m² on white, to simulate typical living room viewing.

On the back of the TV's, what are the screen sizes of each TV? What are the manufacturing countries, factory number, or batch production numbers? What is the manufacturing dates on the back? These may be relevant, because different screen sizes, batches, factories, and years have different quality controls. Obviously, there should be consistency in factories, but that is not always the case. In the reader provided pictures of "NBC logo" & also the other "Youtube screen" I don't see what the reader is talking about. I have purchased a New Old Stock OLED65C6P, so thank you for doing this test (I believe the B6P is the same as the C6P).

B6 label
UJ6300 label
KU6300 label

All three of our units are fairly standard for their model, none have odd panels.
The C6 has roughly the same panel as the B6, just curved.
The NBC logo photos and the YouTube screen photos show what looks like permanent burn in, most visible when the screen is showing red. Both cases have the burn in near the bottom of the screen, where static logos are most often shown. The burn in is visible as small darker areas; other uniformity issues in the photo are mostly camera artifacts.

Interesting that LG is still insisting there is no problem here, especially given the number of folks reporting issues: "However, with an LG OLED TV, any risk of burn-in or image retention have been addressed through the use of technology that not only helps protect against damage to the screen, but features self-healing properties so that any short-term image retention that may occur is quickly rectified. It is rare for an average TV consumer to create an environment that could result in burn-in." (www.lg.com/us/experience-tvs/oled-tv/reliability) The sets are great is no many ways, I'd hate to see all that sidelined due to the company's inability to address a class problem like this. It's sounding more-and-more like lawsuit material, just in time for CES. At home here, we are seeing a small green patch after just under a year of use, primarily due to hours of watching channels with bright logos and news-crawl lines across the bottom-third. No games or other extremes, just normal use... especially for those who fall asleep watching the news every night.
Thank you for your comments, it is indeed unfortunate that LG did not inform its consumers further about the inherent risks associated with burn-in.

"Burn-in on OLEDs unlike Plasma or CRT TVs is not caused by retention or stuck pixels, but instead due to cumulative degradation of the material through usage. This means that over time, OLED TVs will lose brightness across the whole screen progressively. Burn-in is simply a high contrast region of the screen where there was more usage than the surrounding area creating a visible shape. To see the burning-in of the shapes, we'll be taking pictures periodically and will post them on the article." Do you feel that this still applies considering OLED's seem to be a bit brighter and still have significant burnin?
While brightness does have an impact on burn-in, it is important to note that these results are under the most extreme conditions. We do not yet know how OLEDs will perform in the long run.

If burn in with the LG OLED is this bad, then would it be better to buy a Samsung Q7F, which you guys gave a lower rating score? I'm not willing to risk burn in.
The OLED panel on the LG B6 does carry a certain risk of image burn in. If you are unwilling to risk burn in than the Samsung Q7F is a very good TV, and our tests have shown no measurable image retention and almost no risk of burn in.

My 65” inch LG B7 is going to be delivered in probably the next hour! I picked it based on the great reviews it got from you but I never really knew about the burn in risk. Almost every network, every sporting event has static images so why is it rated so high? I’m likely returning this immediately as I don’t want to stress how I use my TV and I want it to last many years. Unless you are using it only for home cinema I don’t know why anyone would risk this unless they are rich enough to buy a top end TV every couple years.
These tests are designed to simulate many years of use in a much shorter time frame. There are many built-in protections on OLED screens to mitigate the impact of static content. At the moment our stance is that burn-in can occur, but most people shouldn't worry about it. As we investigate this issue further (and the test continues to run) we expect to be able to make a more concrete recommendation in the future.

Hello. I am planning on bying the LG Oled B7A. I game a lot but never over maybe 6 to 7 hours in a row. Would I need to worry about Burn in?
Depending on the type of games, some can be riskier in term of burn-in, but we usually suggest to go with an LCD based TV if you worry about burn-in, this way you will have peace of mind in the long run.

I am looking to buy the LG OLED 55inch B7A series. Can i use this TV as a computer monitor? For the whole day? On and off? Some people have told me I could do it, and some have told me that i will get burn in. If the TV has a screen saver built in, will it prevent the burn in from happening? If i use the computer for many hours a day will static images degrade the screen? If I use the image retention cleaner every week, will that prevent the burn in?
Using this TV as a computer monitor for an extended period of time is not recommended. The static nature of the taskbar, icons, menus and wallpaper are likely to cause burn-in issues over a period of a few years depending on usage. The screensaver will mitigate the effect when not in use but a blank screensaver would be a better choice. The pixel refresh feature will help compensate but will not fix or prevent the issue. If burn-in is a cause for concern for you, our current top performance/value for use as a PC monitor are LG SK9000 and Vizio P Series 2018.

Fantastic test thanks for doing this! My question is specifically related to the “break in” period. I don’t see much guidance on this anywhere - some people like to run different colored solid slides, etc. during the first couple hundred hours of use and others just follow normal use with varied content while paying close attention to avoiding static images. I was in the latter for my plasma - and completely avoided any static images during that period and never had any burn in even with hours and hours of multiplayer gaming. I just bought an lg C7 Oled. What specific guidelines can you give about this period - is it actually that critical to break it in for a certain number of hours, or will the pixels wear the same and still be subject to the same risk of burn in regardless? I’ve only been basically watching varied nature shows for the first 20 hours or so and am quite worried I’m not breaking it in even enough to avoid any potential problems. When can I go ahead and start gaming (to a reasonable degree) as well as watching movies with letterboxes? Thanks!
For the moment, we don't have any specific guideline to give about a 'Break-in' period for OLED TVs, as none is suggested in the official documentation, and we did not test this particular aspect of OLED TVs.

Hi, I'm considering buying a 55" B7. The thing is, the TV channel I watch the most - about 2 hours a day - has a very bright white fixed logo that never changes or disappears. I don't do gaming (not much at least). I watch almost entirely at night, in a dimly lit room (warm light behind the TV) and I'm disappointed with the blacks on my current 4K TV, especially when watching HDR. Based on these factors, should I buy the OLED or should I forget about it and purchase a LED (e.g. a Hisense LED)?
We are still very early in our burn-in tests, so we don't really know what the long term results are. Based on what we have seen in our previous test, you may see some burn-in from the logo but probably only after a long time. There are many built-in protections against burn-in such as the Image Refresher that runs automatically after 4 hours of continuous use, and more advanced options such as screen shift. The B7/B7A would be a much better choice than a Hisense LED (such as the H8C). Keep your back light low and you shouldn't have any issues.

I have four of the LG OLED 55" monitors. I use them on film shoots for the client to view what we are shooting. I developed a burn in on one of the monitors and I fixed it by clicking on the Pixel Refresher option in the Picture Settings. It worked for me much to my surprise considering I couldn't find a fix on any websites. Thank you! Charlie Westfall

Thank you for contacting us, and we're happy your problem is solved!

In general Pixel Refresher fixes a big part of the problem, but does not cure it completely as you can see from the results of the Real Life OLED Burn In Test on 6 TVs. This is a test that tries to simulate the Burn-In issue by simulating usage conditions closer to real life, than the 20/7 Burn-In test is. Stay tuned.

I appreciate these burn-in tests. It's great to have someone doing this. However, I do have some concern about OLED suffering the same demise as plasma. Early plasmas quickly earned a reputation for being prone to burn-in, among other things. When I bought one of the last gen Panasonic plasmas, people would comment on how amazing the picture is -- then tell me how crazy I was for buying a plasma. I game on it, I've used the computer on it, and I've watched letterboxed media. It's OK within reason. Years later, it's still burn-in free, because I understand not to stay on a static screen for very long periods of time. There have been occasions I've had image retention, but it goes away after time. Just before reading this, I saw an article posted about LG OLEDs used as displays in airports. They were installed by LG, and this BLEW MY MIND. That is a very poor use for OLEDS, and I'm shocked that LG didn't have the foresight to realize this is a bad idea that will cause negative publicity. I don't feel bad about LG refusing to warranty burn-in. I'm sure it's mentioned in the guide, and it's unfortunately inherent with the technology. I can also understand the frustration of owners. It makes it clear that more consumer education is needed. Maybe LG should have a quick tutorial of what to avoid during the initial TV setup? I will buy an OLED. I'm very excited about microled displays, but I feel it will be a long wait for them to reach my price point. It's unfortunate that even though it's been known for decades now that some displays can be damaged by high-contrast or static imagery, that media still continues to use them. Using "watermark," low contrast, or logos that are moved occasionally would resolve that issue. Having news/stock tickers that slowly fade to different colors would resolve that issue to make sure the wear is even. However, nobody seems to do this.

Glad you enjoy our tests! We haven't seen that particular case of OLEDs being used in Airports, but we're not surprised as LG is heavily marketing their OLED TVs.

While it is still too early to draw any definitive conclusions, OLEDs appear to be less prone to burn-in than plasma TVs, and there are built-in compensation algorithms on all OLED TVs that can even further reduce the possibility of burn-in. We expect that under normal usage, most people will never experience burn-in on an OLED TV.

It will probably be a while before MicroLED technology is ready for consumer TVs. The only TV announced so far is the 146" Samsung The Wall, and reception has been mixed so far. It is unclear if and when Samsung will be able to make the panels small enough for a 55" or 65" model.

It would be great if the media companies adjusted the static elements of their channels to help reduce the possibility of burn-in, but this is unlikely to happen any time soon.

Thanks for doing this extended burn in test. It is a fantastic gift to consumers. I have two questions.
Have you tested, or do you have any advice on the direct sunlight issue that is widely reported on LG OLEDs? Does Pixel Refresher always and completely remove it? Also, does running Pixel Refresher daily cause any unforeseen issues? I have a direct sunlight problem that is not easily physically fixed. I am hoping frequent use of Pixel Refresher will do the trick.

Thank you for contacting us.

No, we have not tested the direct Sunlight issue although we are aware of it.
Pixel Refresher measures how the pixels perform and makes the necessary adjustments to compensate for the "memory" effect that the pixels might have. You can use it as often as you like, we do not think it will cause any issues.
However, the damage caused to pixels from exposure to sunlight might not be fixed by Pixel Refresher as the way it affects the pixels is different from the way the prolonged exposure to an image does. You should protect your TV from direct sunlight to avoid permanent damage.

I am thinking about returning my Q7F QLED for a B7A OLED cause the local dimming and viewing angles on this TV are pretty bad and the OLED looks amazing, but will burn in be a concern if I keep my TV on for about 5 hours a day watching normal content?

Thank you for contacting us.

The LG B7A is a great TV with perfect blacks and wide viewing angles. Like all OLEDS it is prone to burn-in and image retention. Burn-in, however, only happens if you display a static image for a prolonged period of time (like chanel logos, news bars, or Game HUDs, etc.). For normal usage, burn-in should not be your concern, provided you don't display static content like the one mentioned. In the long run (lots of hours of usage) you are more likely to notice brightness degradation rather than burn-in.
If however, you find that you will be worrying too much about burn-in, and viewing angles are a big issue then maybe you look into getting an IPS panel TV, like the LG SK9000.
Keep us posted!

I too am experiencing image retention on my B6 and am very unhappy with it. I put up with the stuck pixel that LG wouldn't cover under warranty after three months, I accepted the motion blur that no setting could correct but I am drawing the line with this latest incident and calling this the Worst. TV. Ever. I watch(ed) CNN extensively in the background while I was working and now have a lovely burned in image of their logo and Breaking News chyron that displays on any reddish screen background. On the off chance that LG would do the right thing I called it in on 5-7-18 and after repeated call backs for status was finally able to speak to a Supervisor today (5-30-18). He was rude and sounded put out that I would dare call for such an issue given that the warranty explicitly says that burn in is not covered. It was apparent that this wasn't the first call he'd received on this issue and it almost felt like he was saying ‘Got you!, enjoy your lousy $4000 TV sucker!’. He even emailed me another copy of the warranty to rub it in. At this point I guess I’ll have to wait for the class action as this is clearly either a design flaw or defective hardware. This ‘you did it to yourself’ attitude may fly with a $200 TV but a TV that cost more than my first four cars combined should come with a reasonable expectation of durability. The LG LCD it replaced never experienced this after the same viewing habits over 8+ years so I really feel that LG should do some explaining, perhaps in court.
We are very sorry to hear that. Unfortunately, image retention is a flaw caused by the design of OLEDs and will probably not be fixed until the next display technology is developed. Since burn-in is caused by the individual pixels becoming dimmer with usage (A static logo, for example, will always turn on the same pixels which will wear out faster), LCD screens should not be subject to this problem as the light comes from the backlight and not the pixels themselves.
