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.
:
VA
Resolution : 4k

The TCL 6 Series (R617/R615) is a very good 4k TV for a wide range of usages. It has good dark scene performance due to the full-array local dimming and high native contrast so blacks appear deep even in a dark room. It is also great for HDR, as it has a great brightness. Although it can produce a wider color gamut than Rec. 709, it isn't as wide as other great HDR TVs. It also has an excellent low input lag for gamers, and unlike last year's TCL P607 it can flicker the backlight to clear up fast motion and interpolate low frame rate content.

The TCL 6 Series is also known as the R615 or R617 depending on the manufacturer variant.

This TV is currently our best Value for Size Under $1,000.

Pros
  • Very bright in HDR and SDR
  • Excellent low input lag for gaming
  • Good local dimming and native contrast produce deep blacks
Cons
  • Picture quality degrades at an angle
  • Uniformity could be better

Score components: Subjectively assigned
TCL R617 Design Picture
Curved : No

The design of the TCL 6 Series is decent, similar to most TCL TVs we have tested. The stand is wide but very stable, and the TV feels slightly bulky due to the square design of the TV's bezel. It will not stand out as a premium TV but is quite functional.

Stand
TCL R617 Stand Picture

Like most TCLs, the R617 has a stand that is nearly the full width of the TV. You will need a very wide table to put it on. It is made from metal and feels strong and sturdy. This change in material is nice from the plastic feel of older TCL models.

Footprint of the 55" TV stand: 47.8" x 10.6"

The legs can also be reversed, in which case the stand measures 28.5" x 10.6".

Back
TCL R617 Back Picture
Wall Mount : Vesa 200x200

The rear of the TV is simple. The top half is metallic and the body is plastic.

There is no cable management, so it can look a bit messy for those who enjoy clean setups with hidden cables.

Borders
TCL R617 Borders Picture
Borders : 0.47" (1.2 cm)

The borders of the TCL 6 Series look decent. They are metallic and have the same finish as the stand legs.

Thickness
TCL R617 Thickness Picture
Max Thickness : 2.95" (7.5 cm)

The TCL 6 Series is comprised of two sections: the electronics compartment and the panel section which is square and has a bulky feel to it. Even though the overall thickness is not bad, it will stick out a little if wall mounted

The TCL 6 Series stays quite cool. In fact, it scored one of the lowest average temperatures of the TVs we tested in 2017-8.

It has two big vents, one on the bottom and one in the back allowing the temperature on the screen to be fairly uniform.

7.0 Build Quality
TCL R617 Build quality picture

The build quality of the TCL 6 Series feels decent. There are no loose panels or gaps, and the TV seems to have a solid construction.

We have received many reports of varying gray uniformity issues between units, which may be indicative of the build quality or quality control.

7.9

Picture Quality

The TCL 6 Series has very good picture quality. The native contrast is excellent, and it has a decent local dimming feature that can further boost the black levels. While blacks aren't as deep as the P607, this is still a great TV for dark room viewing. The TV is much brighter than last year's P607, this is especially noticeable in HDR. Gray uniformity is decent, but we have received reports from many people with much worse uniformity. Like the P607, the viewing angle is bad. Out of the box, colors have good accuracy, and the calibration is easy and fast with the TCL app. Decent color volume, but deep dark colors aren't displayed very well.

The TV has amazing contrast. It matches many of the high end TVs we have tested. Although it does not reach the contrast levels of the TCL P607/605 models it certainly follows their legacy of excellent contrast.

The contrast increases with local dimming since the full array panel manages to darken the blacks without sacrificing much brightness. This is great for dark room performance.

Full-Array

The local dimming on the TCL R615/617 series is decent, and it can produce deeper dark scenes which is very noticeable especially when viewed in a dark room.

On the other hand, there is some obvious clouding around the moving objects. This is because of the inherent limitations of FALD technology and should not worry most people.

Update: The text has been updated to better explain why we see some clouding.

Great SDR peak brightness, it performs well in a bright room. The TV boosts the bright sections of the screen when other areas are dimmer. This is shown by how the smaller window tests are brighter than the larger ones.

This is an improvement from last year's TCL P605/607 and it is much better than the brightness of competing TVs like the Samsung NU7100 and Vizio M Series 2017.

The TCL R617/615 has great HDR peak brightness. Bright highlights in HDR content will be shown fairly bright, very close to the level of 1000-4000 cd/m² they're intended to be.

Overall the HDR brightness is much better than last year's TCL P605/607 which is great.

The gray uniformity of our TCL 55R617 is decent. Especially in the 50% image, clouding is present and there is some dirty screen effect, this is especially noticeable when there is a panning shot during sports.

Uniformity is better in the 5% image although the uniformity remains average. These are similar results to previous TCL models, but lower than the score of the Vizio M Series 2017 or the Sony X720E.

We have received many reports of gray uniformity issues with the TCL 6 Series. The results of our TV seem typical of this model, but many people have received TVs with worse uniformity. Gray uniformity results will vary from unit to unit.

The viewing angle is poor. Blacks and colors shift rapidly as you move away from the front, and the brightness drops quickly as the angle increases a few degrees.

As with most TCLs we have reviewed it is most suitable for a narrow viewing environment.

What it is: The color temperature is a measure of the color of light. A colder color temperature (7000K) will look bluer and a warmer color temperature (4000K) will look yellower/redder. 6500K is the standard color temperature use in the TV and film industry as program, film, and photography directors usually work on monitors calibrated on the 6500k color temperature and do their color correction base on what they see on those monitors.

The 617/615 has to calibrated with the TCL app. Calibration is very easy to do and both the white balance and the CMS respond very well to calibration. The blue dE was not as easy to correct, but remains accurate.

Post calibration, the TV is one of the most accurate TVs on the market. Gamma follows the target curve perfectly, and white balance and color dE are nearly perfect. The overall color temperature is a bit warm still, but very close to the target 6500K.

TCL R617 4k Picture

There are some artifacts visible with 4k content due to the sub-pixel dimming. This performs similarly to the P607 (see here), but shouldn't be an issue for most people and is mostly noticeable when used as a PC monitor.

This type of dithering is uncommon, and is only seen on some TCL TVs, including the S517 and R617. Most people won't notice it much, but occasionally it causes artifacts when it interferes with spatial dithering in games such as this green or purple shadow. (Note: the images are from the S517, but we expect them to be the same on the 6 Series.)

Update 29/05/2018: We have received a report that the 49" S515/S517 has similar crosshatching to the S405, as seen here and we expect this to be the same in the R615/R617. This will bother some people especially when used as a PC Monitor.

TCL R617 EOTF

The TCL 6 Series has a good color gamut, but slightly worse than last year's P607. It supports a wide color gamut, but it isn't as wide as other HDR TVs. HDR will look good, but bright outdoor scenes will lack some detail due to the TV's limited green reproduction.

Note that for this test, a PC was used as a pattern generator. Like many other TCL TVs, the TV detects the PC from the AVI infoframe and automatically switches to a PC mode which behaves a little bit differently. Using a HDFury Integral to mask the AVI infoframe results in a color gamut in the same ballpark, but slightly lower at around 65.8% Rec. 2020 uv.

The TV's Movie EOTF curve follows our input stimulus almost perfectly, but it rolls off sharply as it hits the TV's peak brightness. The PC and Game EOTFs are nearly identical, which is great.

The performance is comparable to the 2017 TCL P605/P607 model although not quite as good. There is some small banding visible in dark reds, greens and grays, but no major banding in any color. Those minor imperfections are not likely to ruin a good HDR movie watching experience.

The pixel structure is quite different from the P607, but there are still artifacts visible with native 4k content as seen in the 4k input box.

The TCL 6 Series has good motion handling. The response time is great, and motion appears clear and relatively flicker-free due to the high backlight refresh rate. It can reduce the backlight frequency to help reduce stutter, but this results in some strange duplications. Movies look great and are judder-free.

The TCL 6 Series has excellent low input lag, as long as Game mode is enabled. With Game mode disabled, input lag is extremely high. 1080p and 4k input lag is very similar. The TV is a 60Hz panel, as such 120Hz input is not supported.

For use as a PC monitor, the TV automatically detects when it is connected to a PC. If it doesn't automatically detect it, changing the input label to Computer will enable PC Mode. For the lowest input lag in PC mode, Game mode must also be enabled.

DTS passthrough doesn't work, which is unexpected since it did on last year's P607.

The frequency response is sub-par. The LFE (Low-frequency extension) is at 143Hz, which means this TV won't produce any thump or rumble, and not a lot of body and punch either. The response above the TV's LFE is relatively well-balanced, which is important for producing clear dialogs. However, since this TV doesn't have a room correction system, it wasn't able to remove the mode of our test room around 200Hz. Additionally, it gets loud enough for most situations, and doesn't produce an excessive amount of compression artifacts under heavier loads.

The distortion performance is about average. The overall amount of harmonic distortion is within good limits at 80dB SPL, but slightly elevated at max volume. This TV also produces high amounts of intermodulation distortion, which could translate to a less transparent treble. Both the effect will be subtle and won't be noticeable to most users.

The TCL 6 Series runs the Roku TV smart platform. The interface isn't as fancy as the competition, but it is very smooth and easy to use. The interface is remarkably fluid, and there are no frames drops or lagging. The Roku companion app is the best one out there, and the TV can cast the audio from native apps to your smartphone, great for late night listening.

Differences between Sizes and Variants

We tested the 55" (55R617). For the most part, we expect our review to be valid for the 65" version (65R617) as well. We have received wide reports of issues with gray uniformity. While we expect our results to be representative of most people's experience, results may vary.

If someone comes across a different type of panel or if their TCL R617 doesn't correspond to our review, let us know and we will update the review.

The variant found at Bestbuy (55R615) is the same TV, but it has a simpler IR remote that requires line-of-sight and does not have the voice control feature.

Warehouse outlets will sell the R613, which is identical to the R617 including the voice remote, but still does not include the private listening feature of the P607.

The TCL R617 is a great, versatile TV that offers excellent value. It outperforms most of the competition in the same price bracket.

TCL P607
55"

The TCL P607/P605 is the predecessor to the R617. It was one of the most popular budget 4k TVs in 2017 and is an excellent gaming TV. The R617 has added motion processing capabilities, including motion interpolation and black frame insertion. They both produce similarly good picture quality, but the TCL 6 Series is brighter. It also has slightly higher input lag, out of game mode, it is much higher, but overall it is still excellent. If you are looking for a new TV, the R617 is a better choice, but it isn't worth upgrading if you already have the P607/605.

Samsung NU7100
40" 43" 50" 55" 58" 65" 75"

The Samsung NU7100 is the entry-level premium LED TV from Samsung for 2018. It is a decent TV with a nicer design than the TCL, but overall performance is worse. The NU7100 has better uniformity, but a worse contrast ratio so dark room viewing isn't as good. It isn't as bright as the R617 and has worse motion performance. They both make great gaming TVs due to their low input lag. Between the two, the 6 Series is a better choice.

Sony X720E
43" 49" 55"

The Sony X720E is a decent budget TV released in late 2017. Overall performance is worse than the R617. It has a poor contrast ratio and no local dimming feature, so dark room performance isn't great. For sports, it is a trade-off between the two. The R617 is brighter, but the X720E has a better viewing angle and has fewer issues with gray uniformity, so it depends on your needs. For use as a PC monitor, get the X720E, otherwise, the R617 is better.

LG UK6300
43" 49" 50" 55" 65"

The LG UK6300 is a decent budget TV. The R617 is better than the UK6300 in almost every way. Similar to the X720E, the UK6300 has better gray uniformity and a wider viewing angle. If your main use is for sports or for use as a PC monitor, the UK6300 or Sony X720E are better choices due to the gray uniformity issues with the R617. Otherwise, the TCL is a better TV.

Good TV for use as a PC monitor. The TV supports chroma 4:4:4 when in PC mode, so text looks sharp and clear. It has low input lag and a good response time which keeps it responsive. The viewing angle is quite limited, so if sitting too close the edges of the screen might fade and lose detail. There are also many reports of uniformity issues, so use for web browsing might be a problem for some people.

Hey just an FYI, the legs can actually be put to face inward so it takes less space.
Thanks for the info! We've added a note in the review.

Just like OLED Burn-in, I don't think you should rate something based on what other people are saying. If your set has build issues or burn-in then rate it, but don't lower a score based on "reports of what other people" are saying. That's not how a review should work. A review should always be based on the reviewers own personal experience with a product.

Thanks for your feedback!

If there were only isolated incidents of this, we normally wouldn't mention this. Unfortunately that isn't the case as there are widespread reports of serious issues with uniformity and banding on the TCL R617, and this is indicative of the level of quality control. We have a responsibility to report this to our readers. Unlike the rest of our review, most of the design section is subjective in nature, and as such is not counted in the over rating for the TV or any of the usage scores.

A "7" for build quality? The TV is composed of more metal than most televisions and the plastic appears to be of high quality. I'm thinking if it didn't have a "TCL" badge stuck on it would have scored higher.

The build quality score was reduced mainly due to multiple reports of broken sets and bad gray uniformity. There appear to be more issues with build quality than usual, which could be indicative of poor quality control. The brand does not have any impact on our score.

Did you guys see the LED full array behind some of the lighter screens like some have reported?

Thank you for contacting us.

The R617 has only decent uniformity. On our unit however, it is not as bad as some we have seen. It should be noted here that uniformity varies from unit to unit.

You say the action smoothing has a low/med/high option, does the low option turn it off? I don't want soap opera effect!
Sorry this wasn't very clear in our review, there is of course an 'off' option. We've updated the review to better show this.

So this will be my first 4k HDR TV and I'm trying to decide if the 65 inch TCL 6-series TV is worth getting, or should I continue saving up for the Sony X930E? I'm trying to go for a TV that does both HDR and Dolby. I just don't know if the Sony TV is worth the $1,999.00 being asked.
Unless you are in a really bright room with lots of glare, the R617 is the better choice. The X930E is a better TV, but for most people the difference is not enough to be worth the price difference.

The 55" has 96 local dimming zones, the 65" has 120, would that lead to a difference in quality? There may be other panel differences as well that they haven't told us. I think the 65" is worth looking into.

We expect our review to be just as valid for the 65" model. The only known difference is the number of local dimming zones. In this case, the higher number of zones is offset by the area they must cover, and when we do the math it actually works that the 65" will have larger dimming zones than the 55", despite the extra backlights.

55": 1293 in² / 96 zones = 13.47 in² / zone
65": 1809 in² / 120 zones = 15.08 in² / zone

4

I'm surprised there was no mention about how the 65" version has more local dimming zones (120 zones vs the 96 zones in the 55" version you reviewed). I wish you had reviewed the 65" version or, better yet, both!

Thank you for contacting us.

We wish we had the resources to test all TVs and all size variances. Unfortunately, we have limited resources, since we buy our own models and we choose to test the most popular one (the 55''). We too have read that the number of local dimming zones on the 65'' is 120 vs 96 on the 55''. If this is true, the 55'' has a denser grid with only 13.46 square inch per dimming zone vs the 15.04 square inch per zone of the 65'' model. However, this should only show that the number of zones should not be the sole criterion when judging local dimming. The algorithm used is also very important and there have been cases where TVs have done a good job with fewer local dimming zones like the 55'' samsung Q8FN that has only 40.

The R617 has a decent local dimming.

The three alternatives mentioned in the review are all considered worse. What's the cheapest option if I want something that actually matches or outperforms this TCL?

Thank you for contacting us.

You can check the Sony X900E. As you will see in the comparison, the X900E is a better TV than the R617, but at a higher price.

To see how you can answer the question yourself, look at the review page of any TV, you will see at the top right hand side the table that shows the scores of the TV in the various usage ratings. Under each rating there are two lines. One reads "Recommended if under (USD)" and the other reads "Value for price beaten by". These two lines can help you choose if the value at which a TV is a good buy, and if there is another TV that performs better at the same cost. Please read the articles and let us know if they are helpful.

Is the Input Lag in Game Mode different(lower) in the other HDMI Inputs, SPECIFICALLY HDMI INPUT 3, as it was suggested in another review. Via Reviewed.com

Thank you for contacting us.

We measured the input lag on all three HDMI inputs (1,2,3-ARC) and found it to be identical. The image settings were the same and Game Mode was on.

I've seen multiple units that have some banding but hardly noticeable with normal content but does banding improve over time with the use of the tv or where the banding stay the same?
Unless the TV has recently suffered a dramatic change in temperature or has been moved around carelessly, which could worsen the banding for a short period of time, the banding on an LCD TV will not change over time.

Hello - there have been quite a few customer complaints of the new 6-series having vertical banding issues. Did you experience this at all with the set you tested?
The TCL 6 series R617 had decent gray uniformity in our most recent tests. It had some noticeable clouding and dirty screen effect. We have heard of customers receiving the R617 with terribly bad uniformity and even our model had some vertical banding. Keep in mind that every LCD TV will be different even if it is the same brand and model, with variations being seemingly huge in the case of the R617.

You may want to mention that you don't get HDR support on inputs unless you MANUALLY set the HDMI to v2.0. The 'auto' setting doesn't work, and obviously the v1.4 compatibility setting doesn't include HDR.
It is true that HDR needs HDMI 2.0 to work. However, we just tested the Auto setting with our Blu-ray player with CEC both enabled and disabled and the R617 would switch to HDMI 2.0 by itself to show HDR content. If your TCL R617 doesn't automatically switch from HDMI 1.4 to HDMI 2.0 to support HDR, the problem is likely caused by your input device.

Hello,
Thanks for doing this review! I have a couple of questions:
1) Would you say the sound is more for listening to dialog vs action sequences (explosions, gunfire etc)?
2) The viewing angle: how does it look if you were looking 'below' the tv at an angle, say you were laying in bed or something where you wouldn't be at eye level.

Thank you for contacting us.

1)Regarding the sound you are right. This TV will not produce good "deep" (i.e. low frequency) sounds. You can expect it to be ok for speech, but when it comes to explosions of gunfire the sound will be less "heavy". If sound is important then you should get a Soundbar.
2)As far as the viewing angle on the vertical axis, we have not tested it. With small angle changes (like the one you mention) we do not expect the image to lose much brightness or color accuracy. With higher angles, the image will deteriorate.

In the TCL R617 review, you have an overall rating of 7.9, but the 55R617 in the chart showing all TVs shows up as 7.7.
On the main TV page, there is a recommendation tool that is designed to help you create your custom rating. The 7.7 score you are seeing is based on the default custom rating settings, and is not based on the mixed usage score. If you adjust any of the sliders or add custom filters you will see that the 7.7 score changes.

TCL R617 TVs have a feature called IPQ ENGINE - Precision color performance tailored to deliver accurate color reproduction and optimized DCI-P3 color space coverage.

I believe this feature is supposed to auto-color-calibrate to give you accurate color automatically. Can you please give us more color (no pun intended) and your opinion on this feature? How well it works (or not works) and if this feature has any noticeable benefit.

Thank you.

The "iPQ Engine" is just TCL's proprietary name for the video processing engine found in the 2018 TCL 5-series and 6-series, like Sony's X1 Extreme or LG's α9 engine. Unfortunately there is no auto-calibration in the TCL R617. The only TV that can perform some sort of self calibration are the high-end Samsungs like the Q9FN, and even they require advanced colorimeter tools and special software.

We found very little difference in colors or video processing between the P607 and R617.

How does this TV compare to the Sony X900F?

The X900F is a better TV in most ways. While overall picture quality is similar, the 900F is better at displaying gradients. It also has better motion handling; it has a lower response time and the 120Hz panel can interpolate 60 fps content up to 120. The R617 has better input lag, but even then, the Sony X900F also has very good input lag.

In the end, it depends on what is important to you. The R617 looks good for most uses, but if you want something better, the X900F is definitely an improvement.

Should we worry about this TV not having HLG HDR Format cause it does have me a bit worry.

Thank you for contacting us.

You should not worry about the HLG HDR format for two reasons. A) there is not a lot of support out there for HLG content and it seems that HDR10 and Dolby Vision will be more widely adapted. B) There are ways to update the firmware and support HLG although this is not likely to happen.
As a final word it's more important that a TV shows HDR correctly and not so much which format it uses.

Checked out rtings on this and the 2017 vizio m series. Really torn. Some have the m series for 849.99. Is Tcl worth a bit more than vizio? I watch mostly sports and some gaming.
Get the R617. It is a significant upgrade over the Vizio M 2017, especially for gaming. The R617 has better input lag, is brighter and has better motion handling. There have been issues reported with gray uniformity, so depending on your specific panel this might be more noticeable when watching sports.

I tried last year's TCL P607 and its visual upscaling and motion handling wasn't as good a I had hoped. The game mode did have low lag time, but the motion wasn't as crisp. Since then I've tried the Vizio 55 P-E1, which had poor upscaling, and high lag HDR. I'm now using a Samsung NU8000 and have been impressed with how smooth the gameplay is, even with flicker turned off. The picture quality is better than either the Vizio (upscaling) and the P607. Is the TCL R617 a better t.v. due to local dimming, than the Samsung NU8000 with a 120hz native refresh rate (which I think has a better picture than the Vizio, for watching tv)?
Overall they both offer similar performance. The R617 has slightly better picture quality, mainly due to the better local dimming and higher peak brightness, especially in HDR. The R617 has some uniformity issues that are especially noticeable when watching sports, making the NU8000 a slightly better choice for sports fans. If you enjoy the soap opera effect, the NU8000 is a better choice as the 120 Hz panel can interpolate 60 fps content up to 120, whereas the R617 can only interpolate as high as 60 fps.

Can you enable HDR in game mode?

Thank you for contacting us.

Yes you can activate HDR in Game Mode.

So this is a 60 Hz tv with a backlight flicker to give the impression of a higher refresh rate? I find it strange that you guys give high scores to motion when it's only 60hz and it's noticeable.

A 60 Hz refresh rate for a TV is just fine, there is not a huge advantage to having a higher refresh rate. It mainly allows the TV interpolate motion up to higher frame rates (Soap Opera Effect), and to display 120 fps content, although that is extremely rare.

Overall, the R617 has good motion handling; there is very little motion trail and it doesn't stutter like some other TVs. The backlight flicker isn't there to give the impression of a higher refresh rate. The optional BFI mode reduces the flicker frequency to help reduce stutter and trick the eye into seeing smoother motion.

1
I see you recommend this over the NU7100 but would you recommend this over the NU8000? Mixed usage in both bright and dark conditions.
The R617 would be the better choice over the NU8000 since it has much better local dimming, which is a major factor when using the TV in a dark environment. The R617 also has better SDR and HDR peak brightness, which is especially important in bright conditions. However, there have been many reports of gray uniformity issues with the R617 due to panel variance, which would make the NU8000 a better choice if you don't want the potential hassle of a bad panel.

Does this TV support HDR10 or Dolby Vision or both?
The R617 does support both HDR10 and Dolby Vision.

Do any 4K TVs upscale non-4K content better than another? I will mainly be watching non-4K satellite TV, so I want the best "upscaled" image. Is this TV one of the best for that for the price?

Thank you for contacting us.

No TV does the perfect upscaling simply because when a TV upscales images, it adds the missing information by interpolation that leads to blur and artifacts.
The new models do a pretty good job. There really isn't any one that works so much better than the others. Also, you must take into account that upscaling from a lower resolution image to 4k will lead to more blur than upscaling a 1080p image. You can try to sharpen the image, but then you will end up with artifacts. Look here for more info.

This TV is the best for this price range.

When Game Mode is enabled, what are you compromising? Why not just leave Game mode on all the tome for the low input lag?

Thank you for contacting us.

Game mode introduces some restrictions on the settings that you are allowed to change. If that is not a problem you can operate the TV in Game mode.

I have a Pioneer Elite Kuro 60" Plasma. I've had my eye on TCL for a while and wanted a 65". Now that this model is out, should I replace the Kuro? Even though my TV is 9 years old, the plasma is still gorgeous.

Thank you for contacting us.

In the last 9 years a lot of things have changed in TV technology.
Resolution has reached 4K, HDR was introduced, input lag is better on most current TVs, and most TVs have turned into Smart Displays with many of them incorporating many Smart features and apps.
If none of the above is a priority or you are worried that you will be regretting your decision because the enhanced features (like HDR) are not justifying the switch then stay with the old one.
If you do decide to switch the TCL 6-series is a great performer and a bang for your buck.

Hello, Rtings. I've recently purchased the TCL 55R617 from Amazon and have it connected to my PC via a Display Port to HDMI cable. However, I can't get my GTX 1080Ti to output a 10-bit signal to it at 60Hz; I can get it to do so at only 30Hz. Is this an inherent limitation of the TV or is this an issue with my setup? I've noticed also that the only color format via which I can output a signal from my PC to the TV is YCbCr 4:2:0.

What resolution are you trying to output? With your setup you should be able to output 1080 @ 60 Hz @ 10-bit RGB, but you definitely won't be able to do the same with 4k. Most of these DisplayPort to HDMI adapters only support HDMI 1.4 (High Speed), and 4k output would be limited to 4:2:0 at 30 Hz with 10-bit color.

Your best option would be to connect with a straight HDMI-HDMI 2.0 cable, but even then the combination of 4k + 10-bit + 60 Hz + 4:4:4 is not possible with HDMI 2.0. You can mix and match but only 3 of the 4, so it could do 4k @ 60Hz with 10-bit color, but only at 4:2:2.

Hello,
I've had the TV for 3-4 weeks now and love it. A lot of the issues talked about in your review and other Reviews don't necessarily apply to me (believing I was very fortunate to have all the pieces come together to work nicely internally). However, I have seen reports of darker corners, and it's not giant by any means and is mostly ignored as I'm playing games or watching movies, but if I'm looking for it, I do see it. Is there anything that can be done to fix or improve that? Worth calling TCL Customer Support about?
Thank you for your time!

Thank you for contacting us.

There is really not much you can do about it. Uniformity is a problem of the thresholds quality control sets on the panel manufacturing process. The stricter the thresholds the more panels will be rejected and thus the more expensive the average cost per TV would be. Although TCL makes great TVs, we have been informed of uniformity issues. If you say that you are not bothered by this issue in the corners, you should just ignore it as you run the risk of getting another panel with another uniformity issue.
Do not worry about it and enjoy your new TV.

Hi in your review was vertical banding only slightly visible in greys and whites, or also in other lighter tones of red, green, blue - is this standard as tcl claims?

Thank you for contacting us.

As you can see from other responses regarding vertical banding issues, uniformity seems to be a big issue with this model. There is really not much that can be done as this is panel specific.
Having said that, in our panel we noticed some minor bandings, but nothing major. Of course what one considers major and minor is very subjective, and this is why we measure the standard deviation of the color differences (dE) between subsequent 10 bit change in shades of various colors and we post the results. This way we end up with an objective score that can be used to compare TVs.

I have an Xbox One X and now the NU8000 supports VRR and FreeSync. This adds an incredible value to the TV as 32+UHD monitors can run 600.00. I'm impressed with how well the VRR works. Shooter games like PUBG are much smoother and more responsive. I also wanted to add that the lag time seems to have gone down also. I frequently, while playing TPP and FPP games, find that I have a significant response time advantage that has really upped my gaming performance. I'm wondering if your testing has produced similar results?
We are happy to hear of your positive experience with your NU8000. The response time is not affected by FreeSync as response time is the time required by a pixel to transition from a color to another. However, with VRR (FreeSync) enabled, the input lag of the NU8000 has considerably gone down in 1440p and is slightly better in 4k and 1080p content. In short, VRR helps to produce a smoother image with more consistent input lag and no screen tearing, which will definitely improve the gaming experience on FreeSync-capable devices.

I'm trying to decide between 3 different TV's: The R617, the Samsung NU8000, and the Sony X900F. I've seen people and this site frequently recommend the older X900E, but it's lack of Dolby Vision or HDR10+ makes it not an option for me.

My main intended usage will revolve around 4k gaming on an Xbox One X, and watching 4k movies and shows via streaming. I've looked at OLEDs but the issues with image retention and burn in seem too risky for me to buy. I want the TV to have a decent viewing angle, low input lag, deep blacks, and the ability to take advantage of either Dolby Vision or HDR10+.

Between the 3 mentioned, which would you recommend to purchase? Is there a better option than those 3? My budget maxes out at about $1500. Thanks!

Go with the Sony X900F, although if you don't mind missing out on Dolby Vision then you could save quite a bit of money (or get a bigger screen) by going with the X900E.

Unfortunately all 3 TVs have VA panels with bad viewing angles. The X900F is marginally better, but the image still degrades significantly when viewed at an angle. The 900F also has the best local dimming feature of the 3, and while the NU8000 has lower input lag it also has worse motion handling. The NU8000 supports a few neat features with the Xbox One X like automatically swapping into game mode and variable refresh rates, and also has lower input lag.

The LG B7A would also be a good alternative, but if you are concerned about burn-in it might be best to stick with a LED TV.

While I found the review TCL 6 Series 2018 R617, since it clearly outperforms the other TVs in it's price range, the comparisons would be more useful if it included comparisons to higher end TV models.

Thank you for contacting us.

You are right. We usually choose to compare TVs with the models they are intended to replace and with models that are fairly similar in price range and release time. It just happens that the TCL is a great TV than could be compared to higher end models.
One interesting comparison is vs the Sony X900E. As you can see here,The Sony is a better TV for most usages (except gaming), but the TCL R617 is pretty close.

Wondering how the 2018 TCL R617 compares to the HiSense 55H9E Plus?

We haven't reviewed the Hisense H9E yet, so we can't really comment on how it compares to the R617. It does have a 120 Hz panel compared to the TCL's 60 Hz, so it will have a stronger motion interpolation feature and it might accept a 120 Hz input.

I have long desired a 65" TCL P series TV, however, I couldn't wait and purchased the Vizio P Series 2017 65". No reviews are comparing these two models (only the 2017 M-series). I debating on returning the Vizio for the TCL, but I can't help be see they are too close to call. Is the Vizio a little better?

Thank you for contacting us.

The Vizio P Series 2017 is better than the TCL P605 Series 2017, but you probably meant to compare the TCL R617 6 series 2018 vs the Vizio P Series 2017.

If you check them on our comparison tool you will see that they are very similar and the TCL R617 is trailing only by little in some categories.

We suggest that you go for the TCL R617. You are saving some money and you are getting a TV that will perform well in almost every situation.

Hello, I recently bought this TV and found that HDR works on my Xbox, but when I connect it to my PC it doesn't show HDR. I have a GTX 1070, and the latest drivers, can you guys help me? Thanks
Thanks for contacting us. Have you enabled HDR and WCG (Wide Color Gamut) in the Windows settings? These settings are located under Start -> Settings -> System -> Display, then HDR and WCG settings. You will also need to go in the NVIDIA Control Panel under desktop size and resolution and set the Output Color Depth to 10 bpc. You can also verify that your graphics card supports HDR by clicking the Windows Key+R then typing in dxdiag and selecting Yes at the prompt. Once that is done, select Save all information, then name and save the text file. Open the text file and look under HDR Support: It will say Supported if it is supported. If you still haven't found the problem, open the file you previously saved to check if the current display connection has an HDR signal. Under Display Color Space, the value should be DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020 if HDR10 is displayed and DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709 if the signal is sRGB and not HDR.

Hello,
Why does gray uniformity have such little influence in your Score/Recommendation/Review? It doesn't matter how good the picture quality/color gamut/HDR is if the screen is bathed in DSE. I know you guys use Hockey or Sports as an example of when it's visible, but it's visible on literally any content (especially games).
Another note, the pixel dimming that causes the purple and green artifacts should really tank your PC monitor scoring as most who have these TV's connected to a PC use them at closer distances where it's visible on any grey webpage. For example, It looks like a really bad cross hatch at the bottom of your very own webpage right now. It makes it unusable as a PC monitor when vegetation in games turns purple.

Thank you for contacting us.

Gray uniformity just like any other attribute can make the screen look bad when it has a very poor performance. Color inaccuracy, bad reflection handing, black uniformity issues, banding, etc. can make an image look really bad when they are way off. Our tests aim not to capture the extreme case when an attribute performs bad, but to try and reach a rating for the TV regarding a specific usage. Therefore we have assigned weights to these attributes according to what we think is the importance of each in each rating. Since we know that this is subjective we are allowing our viewers to create their own rating at the 'BEST TV OF 2018 FOR YOU' section of this page so that they can compare TVs in their own way.

Again this falls into the same category as before. Pixel diming causes artifacts only in very special situations. We are pointing this out in our review, and we show images of how it looks, but we think it would be an exaggeration to call the TV unusable as a PC monitor.

Is there a physical difference between the R615 and R617 (or P605 and P607), or is it just the remote? Are the R615 and P605 capable of working with an RF remote, even though they do not come with one?

Thank you for contacting us.

There is no physical difference between the R615 and the R617 (or P605 and P607). The only difference is the remote that comes along with the TVs. The R617 comes with a more advanced RF remote that does not use IR and can also perform a voice search and use voice commands. The R615 (and the P605) come with a plain IR remote that must have a direct line of sight to the TV to work. Since we only bought the R617 and P607, we have not tested either to see whether they operate with an RF remote. We expect them to work, but remember that with these TVs you can always use your smartphone to take advantage of their good capabilities.

Hi, I was just wondering about the KS8000 55 inch and the TCL 6 series...I have both but I just wanted your guys' expert opinion on both. Which one is better? And if they were both released on the market at the same time, which one would you recommend?.....I’m also maybe a little picky on which one I’m deciding to use as my gaming TV, HDR and everything matters. Thanks!
If you plan on using the TV in a bright environment, the TCL 6 series R617 would be a better choice than the KS8000 due to its higher SDR and HDR Peak Brightness. The input lag (While Game mode is enabled) is also shorter on the R617, but the difference with the input lag of the KS8000 should not be noticeable. However, the KS8000 has better color accuracy and a wider color gamut than the R617. The native contrast of the Samsung KS8000 is also higher than the contrast of the R617. Both of the black and gray uniformity are better on the KS8000. It is important to note that it is not possible to directly compare the results of the KS8000 and the R617 as they were not tested on the same testbench, but we can say that the KS8000 is superior to the R617. If both of these models launched at the same time, it would be hard to recommend one over the other since the price tag of the KS8000 is more than twice the price tag of the R617 and we could not say for sure that the improvement would be worth the price.

I bought the 55-inch M series and I like it but I'm second guessing myself, not super impressed when movies have a lot of dark images, looking into this but have concerns with the vertical banding and uniformity issues. Also the P607 is $100 cheaper than the R617, what is the difference? What do you recommend between the 3?
The TCL P607 2017 is the predecessor of the R617 2018 hence why the R617 is a bit more expensive than the P607. Compared to the Vizio M series and the P607, the R617 has remarkably better Black Frame Insertion (BFI) and much better input lag. The 6 series R617 also supports motion interpolation, which the TCL P607 and the Vizio M series do not. We recommend the TCL R617, but it is important to note that there have been reports of consumers receiving this model with serious uniformity issues caused by panel variance.

Love the site! I had to manually set the TV to HDMI 2.0 for HDR to work with the Xbox One X. No other setting will get HDR to work.
Thank you for the kind comments! It looks like there is indeed a detection issue with the Xbox One as the R617 did not switch automatically to HDMI 2.0 when we connected our Xbox One S. It is necessary to manually set the HDMI port to HDMI 2.0 to support HDR. We will update the review shortly.

I have purchased this 617 and I'm trying to figure out how to get into game mode and make my HDR come on? Also what settings do you recommend for the TV?

Game mode is activated by going into the "Advanced picture settings" menu, and enabling it as seen here.

You can see our settings page here, but in general the 'Movie' picture mode is the most accurate one, and set the color temperature to 'Warm*' In the companion app set the Gamma to 2.2. Brightness settings should be adjusted to your environment; these settings have no impact on picture quality.

Great video on the TCL 6 series but of course I have some nit picking. Although it's not PQ related you should have mentioned the Roku OS is much better than the Android OS, and the YouTube app is HDR capable on the R617, but not on the Sony 900E/900F.

Also, I still think you're missing the boat on the simple but elegant design of the 6 series.

Thanks for the nit picking, we enjoy it! As for Roku OS v. Android, that is really subjective. Many people don't like the limitations of Roku OS and the fact that many settings are only available in the companion app. You have a good point about the YouTube app, but that isn't too much of an issue as there are other ways to get YouTube in HDR on the Sony TVs.

The design of the R617 isn't bad, don't get us wrong! We agree that the design is simple, but elegant, but compared to other TVs out there it is somewhat basic and there are issues with quality control. In the end the design of the TV is highly subjective.

Are the two remotes for the two different models interchangeable? In other words, if I have purchased the 55R615, would I be able to use the slightly-more advanced remote that comes with the 55R617 model (assuming I could find one)?
You would be able to pair the remote, but we don't know for sure if it would work without line-of-sight. We tried pairing other TCL remotes with our R617, and they worked, but only with IR.

Checked out the TCL today at Bestbuy and the picture/number on screen looked jagged. I'll be using the TV as a monitor and was wondering if the LG C8 would be a better option. The B7 is going for $1,100 and the C8 is $1,600, they go on sale often here.
Both of the LG C8 and B7 have much better image quality than the TCL 6 series R617 since they use OLED panels (the R617 uses a VA panel). The C8 and B7 performed very similarly during our most recent tests, the main difference between them being that Black Frame Insertion (BFI) is only supported on the C8. The C8 obtained slightly better results than the B7 in all usages. We recommend the C8 as it has BFI to help clear motion, which is useful when using the TV as a monitor, but you should not be disappointed by the B7 if you don't want to pay the $500 upgrade cost. It is also important to note that since these are OLED panels, there is a risk of permanent image retention, or burn-in.

Under the local dimming section, you say, "On the other hand, there is obvious clouding around the moving objects; this is probably due to the limited number of dimming zones." This doesn't seem to make much sense in view of the fact that the set has a lot more dimming zones than most other sets and certainly more than comparable price-point models.

Thank you for contacting us.

You are right regarding the number of local dimming zones. The wording does give this false impression. We have updated the text to better explain.

What we meant to say is that there is obvious clouding around the object and this is the result of the local dimming algorithm that has only a limited number of zones to work with and thus has to decide which ones to leave on and which ones to switch off. No matter how many local dimming zones there are this will always be the case since there will always be bleeding. This is why only OLED technology gets a perfect score in local dimming.

I was debating between this TV, the Sony 850E and Sony 900E. For the price, what TV is the best value and does this TV not having 120 hz really hurt it?
The TCL R617 would be the best choice of the 3 for most people. The X850E is worse than the X900E and the R617 for roughly the same price. Between the Sony X900E and the TCL R617, the Sony has the advantage of having a 120 Hz panel and a faster response time. The 120 Hz panel isn't a significant upgrade, it mainly allows you to interpolate lower frame rate content up to 120 Hz instead of 60 Hz on the TCL. If you never use motion interpolation (soap opera effect), you're not likely to see much advantage to a 120 Hz panel. Ignoring the 120 Hz panel, the TCL R617 is brighter, has a better black frame insertion feature, and has much better input lag. If you are very sensitive to motion and don't play games, the Sony X900E would be a better choice. We would like to point out though that the TCL R617 has some issues with gray uniformity, if this concerns you then go with the Sony X900E as it is a bit 'safer'.

I'm wondering if you can comment on the local dimming behavior compared to the Vizio 2016/2017 P Series. Both TVs have a similar number of zones, but you rate the P Series very well and this TV gets the same results as last year's TCL P607. Is there really that big of a difference between the two local dimming implementations? Or is your criteria for good dimming evolving as FALD becomes the norm for high-end LED TVs?

Thank you for contacting us.

Unfortunately we no longer have the Vizio P series 2017 to compare side by side. The Vizio had a more aggressive local dimming algorithm than the TCL. The tradeoff is that more aggressive algorithms that dim more zones tend to lose details and small bright spots look dim, but have less clouding. On the other hand, a less aggressive local dimming algorithm will not dim small windows, but will also produce more clouding.
We keep the same criteria when testing within the same test bench so results can be comparable.

How does this compare to the HiSense 55H9E plus?
We haven't reviewed the HiSense 55H9E and there is very little information about the H9E available. The main difference we can see is that the HiSense has a 120 Hz panel.

I'd been waiting all year for this TCL refresh, I am kind of surprised by your sub-8.0 rating. I'm looking for a new 65" TV to be used in an average-lit room, mostly at night, for streaming video, movies, and 4K video gaming, and willing to spend up to $1500. I've been looking at the Sony X900E as well as the Samsung MU8000. But the Sony doesn't have Dolby Vision, and the Samsung I am mostly considering for the brand.

For this TCL, I notice you're only recommending if below $900, but the 65" isn't likely to hit that this year, right?

For your usage, the TCL R617 is probably the best choice. It is better than the Samsung MU8000 and the Sony X900E for video games, and has better dark room performance (better black uniformity and a better native contrast). The Sony X900E is slightly better for movies, but overall you will likely be pleased with the R617. Some people have reported issues with gray uniformity on the TCL R617, so if this concerns you, the MU8000 is a safer choice.

We don't know if the price will drop at all this year, typically there is very little fluctuation in the price of TCL TVs.

Per your own reviews the Sony native YouTube app does NOT support HDR. Please correct the answer to the question I submitted. BTW I meant to say TCL has the advantage in that its YouTube app does support HDR. My bad. Thanks!

p.s. the Android OS on Sony televisions really does really leave a lot to be desired. You do seem to be selective with complaints. Unless there is a scientific basis to evaluate complaints - which we both know isn't the case - you should just evaluate based upon your sample unit.

Thanks for the information! We've corrected the question and answer.

The Android OS may lack some of the polish that other smart OSs have, but in general it is one of the most popular. Thanks for the feedback!

Does CEC work for all HDMI ports or only on HDMI 3?
CEC will work on all HDMI ports. However you may encounter compatibility issues depending on your device brand or model as CEC isn't known for it's reliability.

Why is the 65" R617 not one of the recommended buys for budget category in 65"?
We have limited resources so we normally only update our recommendation articles a few times per year. Due to the popularity of the R617 we've added it now. We will be updating all of our recommendation articles with the latest recommendations in the coming weeks.

Does the built-in cast functionality work with Google Home assistant (i.e. can I say "Hey Google, play X on my TV" and have it play like it does in Chromecast and Vizio Smartcast)?
Unfortunately, this TV doesn't include a Chromecast functionality. It requires a phone, tablet or computer to cast content.

Hi, thanks in advance! I'm wondering which mobile apps you're referencing throughout the review. I'm not sure I see an official TCL app. Thank you.

Thank you for contacting us.

The app referenced in the review is: the Roku app that can be found here

Hi, where on the back of the tv could I attach anti-tip straps?
Safety Strap usually screw into the TV mounting points (VESA holes) which are the 4 screws located in the back center of the TV.

What is the distance between the feet if they are mounted inverted. I want to make sure it fits on my stand.
The 55" model outside dimension is 28 ¾" (73cm) when reversed.

I have a 55" TCL 617 and an HP Envy17 laptop. In trying to connect to movies or TV shows via Hughes satellite (newest generation) the TCL often fails when the laptop does not. Is the larger screen more sensitive to satellite latency than the laptop or is it just the hardware and/or software differences between the two that leads to this? Do dark rain clouds make it worse? Would the TCL be better in game mode? Thanks.
From the symptoms you're describing, it sounds like you may be using WiFi to connect your TV to the internet. If the weather were to affect your reception then the laptop would equally be affected. Your TV's location has a significant influence on the strength of the signal. If you can, try to temporarily hardwire the TV using a long Ethernet cable to see if you still experience the same problem. Another possible solution to is to move your router. Even a couple of feet might do the trick. Other solutions also exist to boost or extend your WiFi coverage.
