Good value: IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.

Resolution : 4k

The Samsung Q9F is the brand's highest-end QLED LCD TV and offers excellent performance for mixed usage. In dark rooms, the high native contrast ratio and great local dimming result in deep dark scenes, and in bright rooms, the excellent anti-reflective coating and high peak brightness help to overcome glare. Unfortunately, when watching sports, some dirty screen effect is noticeable due to nonuniform areas of the screen and the image loses accuracy when viewed at an angle.

Note that this is a different TV to the 2017 QLED Q9F. The 2018 Q9FN is also called the Q9F or Q9.

This TV is currently our best 4k UHD TV - LED Alternative.

Pros
  • Very bright in both SDR and HDR
  • Very low input lag, even with interpolation
  • Great motion handling
Cons
  • Image loses accuracy when viewed at an angle

Update 6/8/2018: FreeSync has been tested and the Variable Refresh Rate box has been updated. The TV's flicker caused some problems with our input lag tool so we don't have VRR input lag measurements yet, but we expect them to be similar to the Q8FN. We'll update the review with input lag measurements soon.

Samsung Q9FN Design Picture
Curved : No

The design of the Samsung 2018 Q9FN QLED TV is excellent. It has a modern, simplistic design that will fit well in any decor. The One Connect box is bigger than last year's, but the cable now provides power as well, so when wall-mounted, the TV only has one very thin cable running to it that can be easily hidden. There are also two alternative stands available if you are looking for something more stylish.

Stand
Samsung Q9FN Stand Picture

The stand of the QN65Q9FNAFXZA is solid and well built. The design does not allow for a soundbar to be placed directly in front, but is designed for the One Connect box to fit neatly behind the TV. The TV is also compatible with replacement stands from Samsung if you are looking for something more stylish, like the Gravity Stand or the Studio Stand.

Footprint of the 65" TV stand: 18.7" x 14.4"

The One Connect box measures 15.4" x 5.2" x 2.6".

Back
Samsung Q9FN Back Picture
Wall Mount : Vesa 400x400

The back of the TV is very simple. There is only the One Connect cable running into the back. There is some flex in the back panel but this shouldn't cause any issues. There is a removable panel to install one of the alternative stands or for the Samsung No Gap Wall Mount.

Borders

Borders : 0.43" (1.1 cm)

The borders of the TV are thin and look good. There is a small gap between the inside edge of the border and the panel.

Thickness

Max Thickness : 1.61" (4.1 cm)

The Samsung Q9F is thin, it can sit flush with the wall when mounted. It is thinner than the Q8FN.

Excellent build quality. There is a lot of plastic, but the border and stand are metal. Like the Q8FN, there is some flex in the back panel but not enough for there to be any issues.

Picture Quality

Great picture quality on the 2018 Samsung Q9 QLED TV. It has an excellent contrast ratio and black uniformity, and the local dimming feature is very effective to improve dark scene performance. It is also one of the brightest TVs we have ever reviewed and has excellent reflection handling, making it a great versatile TV perfect for bright or dark room viewing. It has decent gray uniformity, but there is some dirty screen effect which is noticeable when watching sports. Like all VA panels, the viewing angle is narrow so the best seating is reserved for directly in-front. The Q9FN has a great wide color gamut, but color accuracy is not great out of the box.

Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
:
Full-Array

Great local dimming on the 65" Q9FN. The algorithm is very aggressive at reducing blooming, which creates excellent deep blacks, but some detail may be lost in very dark scenes.

Here is a side-by-side with the Sony Z9D on the left, the Q9FN on the right. The local dimming on the Q9FN is very aggressive even when set to low, so small details in the stars are lost. Those who like the deepest dark scenes may prefer the local dimming algorithm of the Q9FN, but those who are weary about losing dark scene details will prefer less aggressive algorithms.

Excellent brightness for SDR content. While brightness in our real scene test is not as bright as the Sony X930E or Z9D, it is a significant improvement of the 2017 Q9. Small highlights in dim scenes are extremely bright as shown by our 2%, 10% and 25% windows. The Q9FN is an excellent choice even for very bright rooms as the whole screen can get bright as seen in the 100% white window.

Excellent peak brightness in HDR. The Samsung Q9F is one of the brightest TVs we have tested. The TV's local dimming is very effective at producing extremely bright small highlights in dark scenes as shown by the 2% and 10% window brightness.

The Z9D, X930E and X940E are brighter in our real scene test, but small highlights on test patterns are not as bright as the Q9FN.

With the 'Dynamic' picture mode displaying our 10% window, the Q9FN is able to briefly (<5s) spike the brightness as high as 3392 cd/m², the highest brightness level we have ever measured.

The Samsung Q9F has a poor viewing angle, like other VA panels we've tested. Black levels shift significantly when viewed off angle, and the picture dims quite a bit. Colors shift when viewed off-axis, but the shift is not as noticeable. IPS-type LCD TVs like the SK9000 and OLED TVs like the C8 are superior in this regard.

Excellent black uniformity on the Samsung Q9FN 2018. There is very slight clouding around our test cross, but it shouldn't be noticeable and dark room viewing is excellent.

Out of the box color accuracy is poor. Greens and yellows especially are inaccurate. We took our readings with a 100% window, as the local dimming is very aggressive with our regular 18% window and cannot be disabled.

The overall color temperature is not too bad, and gamma is following a curve closer to 2.4 than our target 2.2.

Samsung Q9FN EOTF

The Samsung Q9F has an excellent color gamut, covering almost all of the SDR color space. HDR coverage is very good, the Q9FN displays a wide color gamut, but it is unable to reproduce some of the new green tones in the Rec.2020 color space, very few TVs can. The performance is almost the same as the Q8FN, and we expect that the differences are due to small panel variances.

The Game Mode and PC Mode EOTFs also follow the input stimulus well, which is good.

Update 05/24/2018: HDTVTest has shown that for lower brightness HDR infoframes (such as 1000 nits) the TV produces scenes which are brighter than intended (see his video here). You can see more about this in the Additional review notes.

The Q9FN has great color volume. It is able to produce very bright and very dark colors, across its entire color gamut. It is much similar to the 2017 QLEDs, and much better than the LG C7, B7A and C8.

The color volume on the Q9FN is very similar to that of the Q8FN. The difference should not be noticeable and is likely due to unit variance.

The Samsung Q9FN has great motion handling. It has an excellent response time, and there is very little persistence trail. Like the Q8FN, the backlight has been improved over the 2017 QLEDs, and now flickers at an imperceptible 480 Hz in most modes. It also has an improved optional Black Frame Insertion feature, which can now flicker at 60 Hz in Game Mode to help games appear more fluid and can interpolate lower frame rate content up to 120 Hz, even in Game Mode.

The Samsung Q9 uses PWM to dim the backlight, and it flickers regardless of backlight setting. Similar to the Q8FN, the backlight flicker changes depending on settings. In 'Movie' mode it flickers at 480 Hz which should not be noticeable to most people and doesn't cause any motion duplication.

The Samsung Q9FN can interpolate lower frame rate content up to 120 Hz to help reduce stutter. This function is commonly known as the 'Soap Opera Effect'. Some people find the effect strange, and in scenes with lots of motion there are artifacts. When motion gets too intense the Q9FN, like all Samsung TVs, will stop interpolating, preferring accuracy.

Interpolation is activated by setting 'Auto Motion Plus' to 'Custom'. The 'Judder Reduction' can be adjusted for low frame rate content, and the 'Blur Reduction' slider can be adjusted to help clear up motion on 60 fps content. When interpolation is enabled, the backlight changes to a 120 Hz flicker as seen on the Q8FN here.

The Q9FN is nearly judder free. When playing 24p content through a 60i source, like from a cable box, the Q9FN was inconsistent in removing judder.

The Samsung Q9F does not currently support a variable refresh rate. We tested with the Freesync 2 on the Xbox One S and with a PC with a Radeon RX 580 GPU.

Update 05/23/2018: Firmware version 1103 has added Freesync support. We are currently testing it and will update the review shortly.

Update 06/08/2018: FreeSync has been tested and the score has been updated. FreeSync was supported from our Xbox One S and our Radeon RX 580 GPU, in 1080p, 1440p and 4k resolutions. FreeSync is activated by enabling the TV's Game mode and FreeSync settings; PC mode is not required. We tested in Ultimate mode because it has the widest range, and we only recommend Basic mode when you experience problems with Ultimate.

Excellent low input lag on the 2018 Q9FN across all input resolutions, as long as Game Mode is activated. Excellent low input lag at 120Hz, which is great for gaming.

With Game Motion Plus enabled, input lag is 21.0 ms with 60 Hz interpolation, and 27.3 ms with 120 Hz interpolation.

Update 06/05/2018: Input lag of 1440p @ 120 Hz: 25.2 ms. This input lag was tested at the same time as the others, but was omitted from the review by mistake.

Update 06/11/2018: 1440p @ 120 Hz performance has improved as of firmware version 1103. The 1440p @ 120 Hz input lag is now 10.8 ms, down from 25.2 ms.

The frequency response of the Samsung Q9FN is about average. Low-frequency extension (LEF) is at 113Hz, which is mediocre, especially since the LFE worsens as the TV is put under more load. This results in a bass that's lacking considerable amount of punch/kick, and has no thump/rumble. However, the response above the TV's LFE is quite well-balanced, but since it doesn't have a room correction system, it wasn't able to remove out test room's modes around 200Hz. Also, this TV gets loud-enough for most use cases too, but there will be pumping and compression artifacts present as the TV approaches its limits.

Bottom right: Samsung Q8FN (QN55Q8FNBFXZA).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung Q9FN is a versatile TV that is excellent for a wide range of usages. It has some great features, but comes at a very high price. See some of our comparisons below for how it compares to other TVs on the market.

LG B8
55" 65"

The LG B8 is better than the Samsung Q9FN for mixed usage. If you like watching movies in a dark room the LG will provide you with a much better experience due to its true blacks. Also for those who love sports, the B8 is a better option due to its faster response time, better viewing angles and very good gray uniformity. The Samsung Q9FN can get much brighter which makes it suitable for brighter environments, and it doesn't have a risk of burn-in.

Samsung Q8FN
55" 65" 75"

The Samsung Q8FN is their mid-range QLED for 2018. It doesn't have the One Connect box included with the Q9FN, and the design is a little less advanced. It is a very bright TV, good for bright and dark room viewing, but the Q9FN is even brighter. The Q9FN is a better TV overall for those who want the best, but for most people, the Q8FN is close enough that it's worth saving the money.

LG C8
55" 65" 77"

The LG C8 is one of the latest OLED TVs for 2018. It has exceptional picture quality since the OLED panel is capable of producing true blacks. Compared to the Q9FN, the C8 doesn't perform as well in bright rooms, but it remains accurate when viewed at an angle. The Q9FN can also produce brighter and more vivid highlights in HDR. Overall the C8 is a bit better for dark scenes in a dark room, but if the possibility of burn-in is a concern then an LCD like the Q9FN is a better choice.

Samsung Q9F
65" 75"

The Q9F is last year's flagship QLED. It lacks the full array backlight of the Q9FN and isn't as bright. The 2018 Q9FN is better for dark rooms due to the high native contrast ratio, much better local dimming, and better black uniformity. It also has some neat gaming features through the 'Game Motion Plus' menu. The Q9FN is a better TV.

Sony Z9D
100" 65" 75"

The Sony Z9D is their flagship LED from 2017. It has a similar backlight structure to the Q9FN with similar brightness and picture quality. The Z9D doesn't handle motion as well as the Q9FN, and it has worse input lag for gamers. The best of the two will depend on usage, for gaming the Q9FN is the better choice, otherwise get the cheaper Z9D.

Score components:
Great TV for monitor use. The Samsung Q9 supports chroma 4:4:4 for clear text across all backgrounds. Also, the TV feels responsive due to great motion handling and low input lag. Unfortunately, the sides of the screen look a bit non-uniform due to the narrow viewing angles.

Additional Review Notes

The latest Samsung firmware at the time of testing (1056) had a few bugs with this TV:

  • Multiple times during testing the TV would freeze for ~3 seconds, and wouldn't respond to any remote inputs.
  • In the Movie picture mode, our 20% gray response time square would turn orange when set fullscreen, but when the TV's home menu was opened it went back to gray. To avoid this issue we tested response time in Standard mode rather than Movie.

Hopefully these issues are fixed in a future firmware update.

Based on the comparison tool and reading both reviews for the Q9FN and X930E. Is the improved quality (HDR movies and games specifically) worth the $1800 price difference?

The Q9FN is the best LED TV we have reviewed, if you want the best you can't go wrong with it. The X930E is also an excellent TV. For these specific ratings, the HDR Movies is getting a boost from the higher contrast ratio of the Q9FN, and HDR gaming is getting a score boost from the improved input lag, response time and contrast ratio. Unless you are watching/playing in a pitch-black room, the contrast ratio of the X930E is excellent, and the response time and 4k input lag are very similar between the two TVs. The X930E has much higher input lag for 1080p content though, so if you enjoy gaming on older consoles or games that haven't been updated for 4k yet, you might notice the higher input lag on the X930E.

In the end, it depends on what is important to you. If you want the best and are sensitive to differences in picture quality, get the Q9FN. If that isn't as important to you, you probably won't be disappointed by the X930E.

Hi, My name is Mike and I just purchased the Samsung 75 inch Q9FN TV. Earlier this evening I submitted a question regarding getting my TV professional calibrated. If don’t have my TV calibrated what settings can I try to reduce orange/reddish color of people’s faces in both standard and dynamic mode. Thanks in advanced for your assistance! Mike

Hello again!

For the specific problem (orange/reddish skin colors) try adjusting to a cooler color temperature and if possible set the color space to 'Auto' rather than 'Native'.
You can always go here to get information as to how to adjust the settings of your TV. Although it is not a professional calibration you will be able to adjust the picture to your preferences.
Drop us a note as to how it went! And enjoy your new TV.

Additional Review Notes

An issue was discovered around the way the Q9FN tone maps HDR content. Our testing was done with a simulated 10,000 cd/m² info frame, in which case the Q9FN follows our EOTF curve perfectly until it rolls of at the TV's peak brightness.

The issue is that with a 1,000 cd/m² or 4,000 cd/m² info frame, the Q9FN changes the tone mapping to either brighten or darken the frames, and some scenes don't look as the content creator intended. All TVs do this, but it was especially noticeable on the Q9FN since it is extremely bright and the tone mapping is a little more aggressive than usual.

We investigated this further, and found that the tone mapping could be improved by adjusting the backlight and contrast settings.

How many local dimming zones does the Q9FN have?

We measured 30x16=480 local dimming zones!

5
I noticed that you put the Q8FN in the comparison, highlighting that the Q9FN may not be worth the increase in cost over the Q8FN. Could the same be said about the X900F? Is it a close enough performer to the Q9FN when factoring in a $2200 price difference for the 75 inch model?
Yes, the same could be said for the X900F. The Q9FN is definitely an amazing TV, unless you are in an extremely bright room or it is important for you to have the best of the best, the X900F is a better buy.

Is there a significant difference between the 75" Q9FN vs. 75" or 85" X900F? I am considering the 85" X900F if it is a better value.

Thank you for contacting us.

Generally if someone is interested in TVs with similar performance, but with different sizes, we favor the larger one, provided the viewing distance is adequate.
The Q8FN and the Q9FN are slightly better that the X900F in almost all categories. However, the X900F seems like a better choice for you since you are considering the move to an 85". At this size the X900F is the best in its category and still cheaper that the Q9FN at 75"
You should go with the Sony and you will not be disappointed

Thanks to everyone on the team at RTINGS.com and all the hard work you do. It's greatly appreciated.
I purchased a 65" Q9FN, stunning picture. However, I've run into a few issues, as have a few others.

Receiver issue: from avsforum.com via a Denon rep:
"The core issue that is affecting the passthrough of 4K HDR content is attributed to an unsupported ALLM Mode with Denon receivers, particularly early 2018, 2017, and 2016. Even though the enumerated receivers do support HDMI 2.0, Samsung on their 2018 QLED's supports ALLM Mode which is HDMI 2.1."

The updates are slowly rolling out from Denon, with some models not receiving them until late Summer. The 2015 models and older (including myself) won't be receiving a firmware update. A few Anthem receivers are affected as well.

I can't use my 2015 AVR for my devices and home theater setup. Not Samsung's fault. But in this instance, maybe it is time to upgrade? However, that's another $2,000+ investment. If I were to exchange the tv instead, what alternative would you recommend?

Viewing Area: Softly lit, no windows. Can be pitch black, only when watching movies.
Main Usage: HDR Movies & occasional streaming content. And around 2 to 3 hours of HDR and 1080p gaming a week.

Thanks for your time.

We have seen mixed reports that all affected Denon receivers will be receiving the firmware update. If you decide to replace the TV, based on your usage an OLED TV like the LG B7A/C7 would be perfect for you. Overall picture quality is a bit better than the Q9FN, and they are especially well suited for dark room viewing since the OLED panel is able to turn individual pixels off. As with all OLED panels, there is always the risk of permanent burn-in, but based on your usage it is quite likely that you will never experience this.

Hi, Question is concerning your Additional Review Notes on the EOTF curve.

I can see, through your EOTF plot chart, that the EOTF curve can be adjusted to better follow the intended standard EOTF curve. I am curious in how those adjustments are helpful to someone who just uses the TV with and without calibration. Are these calibrations someone does on the fly? For example, let's say I watch UHD Dolby Vision Blu-Ray mastered at 1000 cd/m², then one mastered at 4000 cd/m² and then finally I watch a Netflix 4K Dolby Vision title. Would the above then require adjustments, for each one every time, to get the tone mapping closer to EOTF curve? If yes, that sounds tedious and is it even possible since the window highlight size changes from scene to scene.

Thank you,
Steve

P.S. Thank you for this wonderful site. My last TV purchase was based on your reviews and I have no regrets with my purchase.

Hi Steve,
Short answer, no, you shouldn't adjust this each time. In the end it depends on how close you want your viewing experience to be to the original content creator's intent. The tone mapping done by the Q9FN isn't bad, it just doesn't follow the original content. Some scenes might seem a bit too bright or a bit too dark, but generally most people shouldn't notice this. In a side-by-side comparison the effect is obvious, but without that comparison it isn't as noticeable. You're right, adjusting the settings on the fly would be extremely tedious and is probably not even realistically possible.

We've provided those EOTF curves so people can see what effect different settings have on the tone mapping. We don't draw any conclusions from them, that is up to each person to decide what is best for them.

Is it possible improve color accuracy Q9FN by firmware?

Thank you for contacting us.

Yes its is possible to change color accuracy by firmware. If Samsung were to choose a different image to use for calibration, then they could send a firmware update to include different image settings. It is highly unlikely that they would do this since it would entail changing their reference for their target gamma.

I was going to get the Q9FN however I've been told for the price it currently isn't worth it and have been advised to consider the Q8FN. However after reading your reviews I'm unsure as to whether the LG B7 or Samsung Q8FN both 65 inches is better for me. My usage is for PS4 Pro, PC gaming at 1080P, movies and TV shows probably split evenly (50% gaming 50% movies and TV) My concern with the LG OLED is it won't get bright enough but is this a valid concern? Thanks
For movies, the LG B7 is clearly better than the Q8FN due to its OLED panel, which creates perfect contrast and blacks by shutting off the emissive pixels when displaying black. The brightness of the B7 is good enough for most bright rooms, but it unfortunately has an Automatic Brightness Limiter (ABL) which lowers the brightness in very high average brightness cases. The ABL should be rarely noticeable during normal TV usage, but will considerably dim the screen when used as a PC monitor (When browsing the web/files with white windows). The LG B7 also performs better than the Q8FN during motion-heavy scenes due to its way faster response time. If your usage is centered around Gaming and Movies/TV shows, the LG B7 OLED would suit your needs the best. It is also important to note that there is a risk of burn-in on all OLED TVs. If you think that you will worry about burn-in, you may be better off going with the Q8FN for the peace of mind.

Vincent Teoh of HDTVtest just recently reviewed the Samsung Q9FN and found some incredibly bad conclusions concerning HDR reproduction on this unit.

Can you confirm whether or not the Q9FN does not track the HDR EOTF curve correctly on your unit? If so, will you be willing to reach out to Samsung for a comment? Thanks!

We were able to recreate the issue, and the good news is that it can be corrected by using different brightness and contrast settings. We have posted an update to our Q9FN review with our results.

Torn between upgrade decisions, maybe you can help.

Have an old V series 65" Panasonic Plasma, have had it for about 7+ years now. At its time it had the best picture quality of any production TV. Have waited to consider upgrading until I felt TVs have offered enough of an upgrade to warrant it (considering how much I spent on the Panasonic). I thought it would be when 4K + OLED combined (at a price compelling enough). With the B7 running $2600 retail (and spiking lower on some sales even) I'm wondering if it's the best choice.
Then this TV came out and it has me wondering about it. Also the X900F seems like a compelling option from Sony too.

I finally feel like there's enough 4k content (and now HDR as well) to warrant considering an upgrade. I love deep blacks and watch a lot of dark content (sci-fi etc), though I watch a variety of content. Watch lots of TV shows, varies in type.

I often work from home so I keep my TV running in the background all day some times. Some of what I watch now is e-sports (Overwatch & CS GO) and I watch a lot of game streaming for long periods of time (think of a 90+ hour games worth of backlogged content that I just keep going for that long over a few days.

Those static UI elements from the streamers and the game has me a bit worried about burn in with OLED. Especially if I plan to keep this for 7+ years again.

I tend to be pretty sensitive to visual quality. I notice the Image Retention I have with my current plasma (though it's not too bad and goes away) and I chose it since it was the best. I'm inclined to wait and get the best quality TV I can now too.

Another factor is I'm wondering if I should wait for hdmi 2.1. In particular 4k at 120hz and VRR. I have a gaming PC with a 1080 ti and run an ultrawide 34" 1440p monitor at 120hz (UW3418DW). I've gotten real used to high refresh rates and like the idea of my future TV being basically a big 4k 120hz monitor (and my rig has the chance to break 60fps in the right settings and games). So wondering if I should just wait for hdmi 2.1 TVs, get one now if a good deal comes along etc.

So many decisions, please help.

Thank you for taking the time to contact us.

Whether it is a good time to upgrade has a lot to do with personal preferences. In the last 7 years that you've had your TV, there have been some changes in TV technology due to the introduction of OLED panels and HDR. As with all new technology the initial implementations aren't perfect. OLED has the burn-in and the Image Retention issue, whereas HDR has yet to be fully exploited. There will always be a new technology just around the corner, but waiting to capture it will only make you miss out on current content.

For the choice of TV, you should consider the following

  • Watching conditions (Bright room? Wide viewing angles? Distance from TV?)
  • Usage
  • Budget
You mentioned 3 models, the LGB7, the X900F, and the Q9FN. All of them will perform well in pretty much any viewing conditions with the OLED giving you better viewing angles. If you compare them side by side using our, comparison tool you will see that the LG B7 is your best choice as it wins in almost every usage.
If budget is not an issue the LG C8 is even better than the B7
Finally if you find yourself worrying too much for the burn in then go with the Samsung Q9FN, and if budget is an issue then the Sony X900F will make you happy. Let us know what you decided.

You mention the remote requires line of sight to turn on, I assume it's IR then, correct? Do you know if the IR receiver is on the TV or the Connect Box?

Interested in getting one of these and I'm hoping I can bury my Harmony Hub in a cabinet with the Connect Box.

The IR receiver is under the TV behind the controls, you can see it here. There would be no problem hiding the One Connect box, there is even a longer fibre optic cable available if you need it.

Hello, First, thank you for the great job you are doing. You are by far the best TV reviewing site I know, hands down. Now, to my question. I understand that the included remote only uses the IR signal to turn the TV on/off, and the Bluetooth for everything else. Is it possible to control the other basic functions of this TV (like Channel up/down, Volume up/down,Inputs, etc.) with a separate IR remote, or the included Bluetooth control is the only option? It would be really nice to use a universal IR remote, if possible. Thanks, Eugene
Thank you for the kind comments! It is indeed possible to control the normal functions of the Q9FN with a linked IR remote. You will need to enter the correct code to sync your remote to your TV as you would do to link any IR remote to a device and you should be all set up. This site contains step-by-step instructions to set up your universal remote and a list of all Samsung 4-digit codes to synchronize your remote to your TV.

Responding to my question 22900. Thanks for the answer. So I after looking at your reviews again and the various other data and reviews out there I went with an LG OLED. Your answer pretty much sums it up, for my use cases the OLED is just better, especially because I keep my living room pretty dim, so the OLED really excels there.
Despite being worried about burn-in I ended up buying a floor model W7 that had burn in (so got it for $2000). The burn-in was minor and having it a few days I almost never see it and love the TV. I did get a warranty that covers burn-in though in case it gets worse or bothers me in the future. Though the image quality is amazing and even with 4700+ hours of screen 'on' time and some burn in (though not nearly as bad as I would've expected), it's just amazing. Also, the W7 form factor is pretty amazing. In an apartment and they let me have the display stand (since they were getting rid of it), which is basically a bit tall piece of thick plexiglass with frosted glass to hide the cord pass through in the back, makes the TV look like it's floating in air.

Thanks for the answer again and this great resource that helped me immensely in making my choice.

Hello,
I just purchased the Samsung 75 inch Q9FN TV. It’s a very nice TV, but the colors out of the box is off. I purchased the TV from Bestbuy in MD. Would you suggest going through Bestbuy to get the set professionally calibrated, or use another source? Thanks in advanced for your assistance! Personally I like the pic with some pop like in Dynamic mode, but that’s a little much. Will having it calibrated in dynamic mode lose the pop?
Thanks
Mike

Thank you for contacting us.

Picture calibration is performed to tune the settings so that your unit reproduces most accurate colors possible, and as you mentioned it is done by a professional with the right equipment.
In your case, however, you might just want to try and adjust the settings yourself. You can start by copying our recommendations. Then depending on the amount of pop you want you can increase the backlight, set the color space to native or use a cooler color temperature.
Let us know how it went.

How many local dimming zones does the 2018 Samsung Q9 have?
This is just an approximation, but our 65" has about 480 local dimming zones (30 columns x 16 rows). It is important to remember that the number of zones is not the only factor, the algorithms play a huge role in the effectiveness of the local dimming feature.

I was able through a Best Buy employee to get the 75" for less than $4200. Most of the time there is indirect sunlight, low light, controlled lighting at night. There are windows across from the TV and I watch DirectTV and Streaming Video (Netflix, Amazon Prime, Google Play) and game as well. At that price, does it pretty much remove all of your comments about getting for less money TVs like the Q8 or 900F?

That is a great price!

The Q9FN is definitely the best LED TV available. For most people, we don't feel that it is worth the price difference over the Q8FN or X900F, but at the end of the day it depends on what is important to you. Even at $4200 that is $500 more than the X900F, and most people won't see much of a difference between the two depending on how sensitive they are to certain things.

What are your pic settings recommendations for movies Samsung Q9FN.
Thanks a lot and keep up

Thank you for contacting us.

We were able to obtain excellent results after our calibration. The settings used can be found on our settings page.. For Movies make sure you chose the 'Picture Mode' to 'Movie' and follow the rest of the settings described in the page. Be sure to adjust the 'Backlight' to a comfortable level according to your viewing preferences. Don't forget to set the 'HDMI UHD Color' to 'on' for each HDMI input that will receive the HDR content. Otherwise you will not be able to enjoy HDR content. And finally one last note. Because each panel is different you might find that the settings are not perfect for you. Try to make small adjustments to match your liking and if it doesn't work, you might have to look for a professional calibrator.
Let us know how it went.

Did you guys notice any weird fluctuation with the local dimming in some dark content like credits at the end of a movie? It's almost like it can't decide what brightness to use. I've seen it in the new God of War game as well. If I'm in a dark cave with a little light the local dimming "flickers" to full screen and back to just the object it's highlighting. Not sure if I explained that correctly or not. It doesn't happen all the time but the issue is there.

We didn't have any similar issues. We tested it again with rolling credits of a movie and there were no issues. Unfortunately we don't have the new God of War and aren't able to test with that. What you are describing is related to the local dimming algorithms. We tested with the latest firmware which was supposed to improve the local dimming feature. Have you updated your Q9FN to the latest firmware and have you tried adjusting the level of local dimming? Another thing you can try is to disable all eco settings, as they can cause similar issues.

Recently bought the 75Q9FN and thinking maybe the 85X900F could have been a better choice for a bigger TV. Can you elaborate on what is the better choice and why? Thanks

Thank you for contacting us.

Generally if someone is interested in TVs with similar performance, but with different sizes, we favor the larger one, provided the viewing distance is adequate.
In your case the Q9FN is marginally better than the X900F in almost every usage category as you can see here, so It really comes down to personal preference.

There is a lot of confusing information out on the web regarding the number of local dimming zones on the Q9FN. Since on the Q8FN review you have stated that there are 40 such zones is it double on the Q9FN? 80? And do the number of zones increase based on the size of the television?

Thank you for contacting us!

We ONLY measured the number of local dimming zones of the units we tested. That is the 55" Q8FN where we found 40 local dimming zones, and the 65" Q9FN where we found 480 local dimming zones. For the units that we haven't tested we can not be sure of the number of local dimming zones they have. Usually the number of local dimming zones does increase with TV size, although this is not certain.

Local dimming is associated with the level of black a TV can produce. The number of local dimming zones is not the only factor that matters. Aggressiveness of the algorithm that performs local dimming is another to just name one. Please read our article on local dimming to find out more.

I haven’t seen a review from your site on the new Samsung Q6F Qled line. I’m deciding between this, the NU8000, or older MU8000 model in 65”. The prices range from $1000 for the MU8000 to $2000 for the Q6F. I will be using it primarily for 4K movie, Blu-ray, and some gaming, but still do watch standard definition channels. Any recommendations would help, thank you!

We've received the Q6FN in our lab, but haven't had a chance to review it yet. It should be done within about a month.

Between the NU8000 and MU8000, they are very similar, go with whichever one is cheaper.

What are the dimensions of the One Connect box?

The One Connect box on the Q9FN measures 15.4" x 5.2" x 2.6" (39 x 13.2 x 6.7cm). We've added a note in the review section.

The Q9FN has received stellar reviews from all notable TV review sites including this site, the only exception would be HDTV test, when Vincent has claimed that the Q9FN over brightens SDR and HDR content and doesn't follow the standard ETOF curve, thus it isn't a good product. Would you be so kind to give me your professional opinion on this matter?
We definitely wouldn't say that this isn't a good product. All TVs tone map to some extent, the Q9FN is just a little more aggressive than most. The good news is that this is easily corrected with the correct settings, we've added a note to our review here. While this issue is more noticeable when doing a side-by-side comparison like Vincent did, most people wouldn't notice it on its own.

Just and FYI: Samsung has unlocked the Freesync option in the Q9FN’s game settings menu. Also Microsoft unlocked the VRR option in the Xbox One X and Xbox One S options menu so you may want to update this review.
Thanks for the info! We are currently testing this as the feature has been added to all of the 2018 Samsung QLEDs and the NU8000.

Vincent from HDTVTest said the 2018 Q9 had a gradient smoothing feature hidden within its Digital Clean View like LG's 2018 MPEG Noise Reduction. Is this feature only on the Q9 or all 2018 Samsung TVs?

Thank you for contacting us.

We tested Digital Clean on the Q9FN and when we set it to Auto we did notice a gradient smoothing. The smoothing was not noticeable when Digital Clean was set to low. We also tested it with similar results on the NU7100, and thus we expect this feature to be available on all 2018 Samsung TVs

Does the Q9FN support eARC?

Thank you for contacting us.

No the Q9FN does not support eARC. No TV supports this protocol yet, and we have no way of testing it

What is the input lag with bfi turned on in game mode? Can bfi be turned on with input labeled pc?

Thank you for contacting us.

We measured the input lag with BFI on and in Game mode to be: 25.7ms
For your second question: Even if we turn BFI on and the label of the input of the TV shows PC, it is not in real PC mode since the color 444 is not shown.

I recently ordered and am waiting for my Q9FN 75 inch to be delivered. What are the specifications of the HDMI ports and what HDMI cables would you recommend for Apple TV 4K and Xbox One S ?
On the Samsung Q9FN, all 4 of the HDMI ports support HDMI 2.0 full bandwidth, which is required for high bandwidth signals such as 4k @60Hz with Chroma 4:4:4. If you plan on using a receiver with your Q9FN, note that only the HDMI port #4 can be used as Audio Return Channel (ARC), which will send the audio from your TV to the receiver. It is also important to note that only Dolby digital (Through both ARC and Optical) is supported on the Q9FN, DTS (Both ARC and Optical) is not supported on this TV. You will need HDMI 2.0 cables to transmit the bandwidth necessary for high resolutions.

I'm currently debating between buying the 65" Q9FN or the Sony 75" X940E. Is there a big difference in picture quality? I will be using it mostly for watching HDR movies, sports, and some gaming on the PS4 pro (FIFA 18). I could still get the X940E on amazon for the same price of the 65" Q9FN. Which one would you recommend?

Unless your seating area is farther from the TV and you need the bigger screen, get the Q9FN. You will really appreciate the much better motion handling, especially when playing FIFA or watching the World Cup.

0
Would you recommend the 75 in Q9FN or the 85 in 900F for mixed usage of 75% streaming 4k and 1080p content, and 25% gaming from a PS4 Pro?
While the Q9FN is a better TV than the X900F for your usage, it isn't worth the price difference. Between these two, get the Sony X900F.

What's your opinion of the lack of Dolby Vision in the Samsung Q8FN vs. the potential burn-in issues with the LG C8 that does support DV? It's a hard choice spending premium $ on a set that does not support Dolby Vision.
Thanks

Dolby Vision isn't enough of an upgrade to warrant spending more on a TV just to get it. If burn-in is a concern for you, get the Q8FN, most likely you will never even notice that it doesn't have DV.

I noticed the input lag with the interpolation is actually lower than without. Is this really the case?
Sort of; on this TV the input lag with interpolation was actually measured in game mode, because this year Samsung introduced a new Game Motion Plus feature that adds motion interpolation and optional flicker into game mode. Game Motion Plus's interpolation isn't as good as the out-of-game-mode Auto Motion Plus, but it has much lower input lag, even lower than the normal out-of-game-mode input lag.

In the photos of the under-TV controls I see two screws. If you remove them does the Samsung logo pop off? As petty as it sounds, I hate that it ruins an otherwise minimal border to the TV. Thanks!
Unfortunately, no. The logo is attached to a small plate that holds the IR receiver and the TV controls. The screws can be removed to remove this plate, but the TV won't function without it. The main bezel does not continue under the logo, so removing it would just leave an empty gap.

And I thought the score for local dimming on the Q8FN was a shill score. Wow. You scored this beast lower than the Z9D? I don't think you realize how absurd this seems. Do the comparison on your own site. Go to your local dimming score for both TVs. Now scroll up. Right above your local dimming score are the test results for contrast "with local dimming". Your results say that the Q9FN doubles the Z9D. And how about that black uniformity with local dimming where the Q9FN wins again. I get it. Subjective. Well isn't motion subjective? But we rely on your numbers for that. If this was one "subjective" score all on its own then this could be overlooked, but this score influences 3 other scores, movies, HDR movies and HDR gaming. Not to mention the stand alone score of picture quality. Your own numbers say one TV way way way outperforms the other, and yet you favor the sony. I'm sure this means nothing to lose one person from your fanbase, because I was part of that group for 3 years and have told many people about your site,but when other people catch on to how Sony biased you've become, you will lose more. Hopefully you make corrections where needed and are able to keep going. Best of luck.

Thank you for contacting us and pointing out your concerns.
Your comments show that you have read very thoroughly the test results. We did compare both TVs side-by-side for a significant length of time and on lots of different content before deciding on these subjective scores. We believe that the difference between expectation from these tests and the local dimming score is because these tests focus on one aspect of local dimming (how much it can darken dark scenes) but the local dimming test aims to capture the overall performance.

The local dimming of the Q9FN is very aggressive, and it tends to darken small highlights. This does look great on dark scenes, but when compared side-by-side with another TV it is apparent that significant areas of detail are lost. As an example, here is the Z9D on the left and the Q9FN on the right. The Q9FN is able to produce deeper dark scenes, but completely crushes most of the stars and details in the scene. This is why the Q9FN scores worse - the black crush isn't always apparent, but with small highlights significant details can be lost.
