The TCL 6 Series 2019 55R625 / 65R625 is an impressive budget 4k TV with great picture quality. It has a low input lag that's great for gaming and delivers deep blacks in a dark room thanks to its outstanding contrast ratio, excellent blacks, and good local dimming support. It can get very bright in SDR and displays vivid color with bright highlights when in HDR. It has a fast overall response time and motion looks crisp, but some scenes have some noticeable motion artifacts. Unfortunately, the gray uniformity is just decent and most people will notice some dirty screen effect. Finally, the image degrades when viewed from the side just like with most VA panel TVs.

Update 11/20/2019: The TCL 6 Series R625 2019 was originally reviewed on October 16 2019. The text has been updated, but our overall findings haven't changed.

Our Verdict

8.1 Mixed Usage

Overall, the TCL 6 Series/R625 2019 is an impressive TV for most uses. It has a high contrast ratio and displays deep, uniform blacks in a dark room. It's also a great TV for use as a PC monitor or for playing games on a console thanks to its very low input lag. Although the TV is suitable for a bright room thanks to its high brightness levels, the image loses accuracy at an angle, which isn't ideal when watching sports with a group of friends or doing chores while watching TV shows.

See our Mixed Usage recommendations
8.5 Movies

This is a great TV for watching movies in a dark room. It has outstanding contrast, a good local dimming feature, and excellent black uniformity. It can remove judder from all sources, without introducing the soap opera effect. Blu-rays and other lower-resolution content is upscaled well and looks great. Unfortunately, there are noticeable uniformity issues, and the image degrades at an angle, so it isn't great for a wide seating area.

See our Movies recommendations
7.5 TV Shows

Overall, this is a good TV for watching TV shows during the day in a bright room. It can get very bright and has decent reflection handling, so glare shouldn't be an issue. It has a very large number of apps, called streaming channels, and it upscales lower resolution content well. Unfortunately, the image loses accuracy when viewed from the side, so it isn't great if you do chores while watching TV.

See our TV Shows recommendations
7.3 Sports

The R625 is a decent TV for watching sports, but it's best-suited for watching the game with only a small group of friends. It has decent reflection handling, great peak brightness, and a good response time, but some motion artifacts and duplications can be seen in fast-moving content. Unfortunately, the image degrades at an angle, so it isn't great for watching with a large group of friends, and the gray uniformity isn't great.

See our Sports recommendations
8.7 Video Games

Excellent TV for playing video games. The input lag is remarkably low and the response time is fast so that the image is crisp. It has an excellent contrast ratio and outstanding black uniformity, great for dark-room gaming. Unfortunately, some motion issues and artifacts can be seen, especially in dark content. Finally, there's no support for any advanced gaming features, like FreeSync.

See our Video Games recommendations
8.5 HDR Movies

This is an excellent TV for watching the latest movies in HDR. It has excellent contrast and outstanding black uniformity, resulting in deep, uniform blacks, and it has a good local dimming feature. It has great HDR peak brightness, so small highlights stand out, and it can display an excellent wide color gamut. Unfortunately, it has only decent gray uniformity, and some banding and dirty screen effect can be seen in some content.

See our HDR Movies recommendations
8.6 HDR Gaming

The TCL R625 is an excellent TV for gaming in HDR. It has outstanding low input lag and a fast response time, for a responsive gaming experience. It has an excellent contrast ratio, delivering deep, uniform blacks, and it can display a wide color gamut. Unfortunately, some motion artifacts can be seen in some content, including duplications in fast-moving content.

See our HDR Gaming recommendations
8.2 PC Monitor

The TCL 6 Series R625 is an impressive TV for use as a PC monitor. It has an exceptionally low input lag and a fast response time for crisp motion. It displays chroma 4:4:4 properly, so the text looks clear but only when sents a 4k input signal. If you sit up close you will notice some image uniformity issues at the sides due to the disappointing viewing angles. Finally, you should avoid placing it in a room with many lights as reflection handling is only decent.

Market Context

The TCL 6 Series 2019 replaces the TCL 6 Series/R617 2018. It's one of TCL's most popular models, and its main competitors are the Vizio M Series Quantum 2019, the Hisense H9F, and the Samsung Q70/Q70R QLED. Although it was TCL's highest-end model last year, this year they're releasing the TCL Q825, a high-end model designed to compete with premium models from other brands.

Design
8.0
Design
Style
Curved No

The TCL 6 Series 2019 has a great design. TCL has updated the design this year, adding a few nice touches, including a partial chrome finish on the feet and a glossy panel on the back. All of these changes add a premium look to this TV, and it feels solid and well-built. Unfortunately, there's still no cable management.

Design
Stand

The feet are attached to the side of the TV, which is unique, but this TV requires a wide table if it isn't wall-mounted. There are covers included in the box to hide the mounting slots for the feet when wall-mounted.

Footprint of the 65" stand: 56.7" x 12.6"

Design
Back
Wall Mount VESA 300x300

The back of the TV looks like last year's model, except that the top half has now a new glossy panel. This panel adds a premium look to the TV and appears to be purely cosmetic.

Unfortunately, like last year's TCL 6 Series 2018, there's absolutely no cable management.

Design
Borders
Borders 0.35" (0.9 cm)

The TCL 65R625's borders are thin and aren't distracting when watching TV.

Design
Thickness
Max Thickness 3.39" (8.6 cm)

The TCL 65R625 is thicker than most TVs we've tested, so it might stick out a bit when wall-mounted.

Design
Build Quality

Overall, the TCL 65R625 has good build quality. The stand supports the TV well with very little wobble. It appears to be well-built, with no obvious issues, but we have received a few reports of damaged screens out of the box.

The TCL 6 Series 2019's contrast ratio is excellent. It delivers deep blacks in a dark room and when local dimming is enabled the result is even better. This is an improvement over last year's TCL 6 Series 2018.

Backlight
Full-Array

The TCL R625 has a good full-array local dimming system, much better than last year's TCL R617. The dimming algorithms can be a bit too aggressive with some content, though, causing some areas to dim a bit too much, but most regular content looks good. There's some noticeable blooming around subtitles, but it isn't as bad as most Samsung TVs.

The 55" inch model has fewer local dimming zones (100 instead of 120), but we don't expect this to have a significant impact on local dimming performance.

Great peak brightness in SDR, more than bright enough for the most difficult environments. It's not quite as bright as the TCL R617, but this shouldn't be very noticeable with SDR content.

We measured the peak brightness after calibration, with the 'Brighter' setting, with the Backlight set to '100' (max) in the 'Movie' Picture Mode, as these are the most accurate settings. Unlike many TVs, these are also the settings that deliver the highest peak brightness.

Great peak brightness in HDR, but it isn't as bright as last year's TCL R617 or the Hisense H9F, so small highlights aren't quite as bright in some scenes.

We measured the peak brightness in HDR before calibration, with the 'Dark HDR' Picture Mode, which is the most accurate and the brightest setting.

Note 10/17/2019: Gray uniformity varies on a unit-by-unit basis, so if you buy this TV then let us know how your unit compares in the discussions.

Unfortunately, the TCL 6 Series 2019 has only decent gray uniformity. There's significant vertical banding across the entire screen, and the corners are darker than the rest (also known as vignetting). This is especially disappointing for sports fans, but it's noticeable in most content.

The TCL R625's viewing angles are disappointing but are still an improvement over last year's TCL R617. If you don't sit directly in front, then you should consider a TV with an IPS panel, like the Sony X800G where the image remains accurate for wider angles.

The TCL R625's pre-calibration color accuracy is sub-par. You don't have to be an enthusiast to depict most of the errors in the gray shades and some colors. The color temperature is warm and you'll notice some red and yellowish tint. Gamma doesn't follow the target curve, so most scenes are displayed darker than they should be.

After calibration, the TCL R625 has much better accuracy. There are still a few remaining inaccuracies, but most people won't notice anything.

TCL originally announced that the TCL 6 Series 2019 will have an auto-calibration function. Unfortunately, this feature hasn't been released yet, so we haven't been able to try it. Once the app is out we will reset the TV and test the auto-calibration, and post our findings in a discussion post below.

4k Input

4k content is displayed nearly perfectly on the TCL R625. Unlike the TCL R617, there's no sub-pixel dithering, but we noticed some minor cross-hatching in some content. It isn't very noticeable, though, and you have to be close to notice it. From a comfortable viewing distance, it shouldn't be an issue.

Update 10/17/2019: Added clarifications to text.

This TV has an outstanding color gamut, similar to most OLED TVs we've tested, like the LG C9 OLED, and very close to the Samsung Q9FN. This is expected, as the quantum dot color used to produce a wide color gamut was one of the main advertised features of this TV. It's a noticeable improvement over the TCL R617, and is important for more saturated colors with the latest 4k HDR movies.

Unfortunately, the EOTF (electro-optical transfer function) doesn't follow the target PQ curve, and most scenes are displayed brighter than they should be. 'Game' mode is a bit more accurate, as shown here.

If you find HDR too dark, check out our settings page to see how to make it brighter.

The TCL 6 Series 2019 has great color volume. It's mainly limited by the incomplete color gamut, as it can display dark saturated colors well, and most colors are as bright as pure white.

The TCL 6 Series R625 2019 has a good overall response time. However, some dark scene transitions are slow and this displays as ghosting which is noticeable and will distract some people. Also, the TV's backlight flicker, which can't be disabled, causes some duplications and some motion artifacts that can be annoying. This behavior is depicted in the above response time photo.

The TCL 6 Series 2019 can display chroma 4:4:4 properly, but only in 4k. When sending a 1080p or 1440p signal from a PC, it can't display chroma 4:4:4 properly, so text doesn't look clear. This is very surprising, as almost all 4k TVs can do this, so we expect it's a bug with the current firmware. We'll retest this with future firmware updates.
