The TCL 6 Series/R655 2022 QLED is a mid-range 4k TV released in 2022 that runs the Roku TV smart interface. It sits above the TCL 5 Series/S555 2022 QLED and replaces the TCL 6 Series/R635 2020 QLED. It's available along with the TCL 6 Series/R646 2021 QLED, which runs the Google TV smart interface instead of Roku TV. It has a few new features compared to the R635, including a faster 144Hz refresh rate and a Mini LED backlight that's designed to improve local dimming performance while increasing peak brightness. It's available in 55-inch, 65-inch, 75-inch, and 85-inch sizes, so there are options available for many different needs, and all sizes perform the same.

Our Verdict

8.3 Mixed Usage

The TCL 6 Series Roku TV is great overall. It's a versatile TV that looks great in both bright and dark rooms. It can easily overcome glare, making it a very good choice for watching sports or shows during the day, but it's a bit limited by its narrow viewing angle, as the image degrades from the sides. It's impressive for watching movies in the dark, thanks to its fantastic contrast ratio and decent local dimming. It has a wide color gamut and excellent gradient handling for HDR content. It also delivers an amazing gaming experience thanks to its low input lag, fast response time, and variable refresh rate support.

Pros
  • Fantastic contrast ratio results in deep blacks in a dark room.
  • Great selection of streaming apps.
  • Superb reflection handling.
  • High peak brightness.
Cons
  • Image degrades rapidly when viewed from the side.
8.3 Movies

The TCL 6 Series Roku TV is impressive for watching movies in a completely dark room. It has a fantastic contrast ratio and decent Mini LED local dimming feature, so blacks appear very dark and uniform in a dark room. Bright highlights stand out well in dark scenes, and blacks aren't washed out, but they're raised a bit by the local dimming feature. It automatically removes judder from any source, ensuring a smooth movie-watching experience. It upscales 1080p content, like Blu-ray movies, well, but unfortunately, DVDs aren't displayed properly.

Pros
  • Fantastic contrast ratio results in deep blacks in a dark room.
  • Great selection of streaming apps.
  • Automatically removes judder from any source.
  • High peak brightness.
Cons
  • 480p content isn't upscaled properly.
  • Some stutter in slow panning shots.
8.2 TV Shows

The TCL 6 Series Roku TV is very good for watching shows during the day. It has remarkable peak brightness in SDR and superb reflection handling, so it can easily overcome glare in a bright room. The built-in Roku smart interface has a great selection of streaming apps, so you can easily find your favorite shows. Unfortunately, it doesn't upscale 480p sources properly and has a poor viewing angle, so it's not a good choice for a wider seating arrangement as the image fades and looks washed out from the sides.

Pros
  • Great selection of streaming apps.
  • Superb reflection handling.
  • High peak brightness.
Cons
  • Image degrades rapidly when viewed from the side.
  • 480p content isn't upscaled properly.
8.1 Sports

The TCL 6 Series Roku TV is very good for watching sports in a bright room. It gets remarkably bright in SDR, and, combined with its superb reflection handling, it can handle a lot of glare if you're in a bright room. The response time is good enough that you won't see much blur behind fast-moving objects, and it has good gray uniformity. Unfortunately, it has a poor viewing angle, so it's not a good choice for a wide seating arrangement, as the image fades and colors look washed out when viewed from the side.

Pros
  • Great selection of streaming apps.
  • Superb reflection handling.
  • High peak brightness.
Cons
  • Image degrades rapidly when viewed from the side.
8.7 Video Games

The TCL 6 Series Roku TV delivers an amazing gaming experience. It has an incredibly fast refresh rate, resulting in clear motion with very little blur. It also has a great selection of gaming features, including low input lag and variable refresh rate support to reduce tearing in games. It supports 4k @ 120Hz gaming from new-gen consoles, and it supports HDMI 2.1 bandwidth on two of its HDMI ports. Unfortunately, although it's one of the only TVs on the market to support a 144Hz refresh rate, the input lag increases at 144Hz.

Pros
  • Fantastic contrast ratio results in deep blacks in a dark room.
  • Superb low input lag for a responsive gaming experience.
  • Extremely fast refresh rate.
  • High peak brightness.
Cons
  • Input lag increases at 144Hz.

It has a fantastic contrast ratio and decent local dimming feature, so combined with its high peak brightness in HDR, bright highlights in HDR content stand out incredibly well. It tracks the PQ EOTF well, ensuring it respects the content creator's intent and has a wide color gamut. It also has excellent gradient handling, with very little banding in areas of similar color, and it automatically removes judder from any source.

Pros
  • Fantastic contrast ratio results in deep blacks in a dark room.
  • Great selection of streaming apps.
  • Automatically removes judder from any source.
  • Wide color gamut with HDR content.
  • High peak brightness.
  • Great PQ EOTF tracking.
Cons
  • Some stutter in slow panning shots.
8.6 HDR Gaming

The TCL 6 Series Roku TV delivers an excellent gaming experience in HDR. It delivers an amazing gaming experience overall thanks to its fast refresh rate, low input lag, and fast response time. HDR content looks great thanks to its fantastic contrast ratio, decent local dimming feature, and wide color gamut. It also has amazing peak brightness in HDR, so bright highlights in games stand out well.

Pros
  • Fantastic contrast ratio results in deep blacks in a dark room.
  • Superb low input lag for a responsive gaming experience.
  • Wide color gamut with HDR content.
  • Extremely fast refresh rate.
  • High peak brightness.
  • Great PQ EOTF tracking.
Cons
  • Input lag increases at 144Hz.
8.2 PC Monitor

The TCL 6 Series Roku TV is very good for use as a PC monitor. It has low input lag and a fast response time, ensuring a smooth, responsive desktop experience. It also gets very bright and has superb reflection handling, so you don't have to worry about glare in a bright room. Although it displays chroma 4:4:4 properly for clear text from a PC, it can only do so at 60Hz; if you send anything higher, it'll just skip frames. Unfortunately, it has a narrow viewing angle, so the sides of the screen appear dull and non-uniform if you're sitting up close.

Pros
  • Superb reflection handling.
  • Extremely fast refresh rate.
  • Chroma 4:4:4 is displayed properly for clear text.
  • High peak brightness.
Cons

  3. Updated Nov 22, 2022: Early access published.

Differences Between Sizes And Variants

We bought and tested the 55-inch TCL 6 Series Roku TV, and our results are also valid for the 65, 75, and 85-inch models. There's another 6-series TV still available, the TCL 6 Series/R646 2021 QLED; it's a very similar TV but runs the Google TV smart platform instead of Roku. The larger sizes perform roughly the same, but they have a slightly better local dimming feature thanks to the increased number of dimming zones. The 85" model performs mostly the same, but it's limited to a 120Hz refresh rate and a slightly different design, with feet instead of the center-mounted stand.

Size Model Number Dimming Zones Max Refresh Rate
55" 55R655 240 144Hz
65" 65R655 288 144Hz
75" 75R655 360 144Hz
85"  85R655 448 120Hz

You can see the label for our unit here.

Compared To Other TVs

The TCL 6 Series Roku TV is a well-equipped TV that delivers impressive performance for the price, with better picture quality than most similarly-priced models. It offers better performance and picture quality than budget TVs while also costing less than most mid-range options. Although there are better TVs available, you'll have to pay considerably more for slightly better performance.

See our recommendations for the best smart TVs, the best TVs under $1,500, and the best 4k TVs.

Hisense U8H
55" 65" 75"

The Hisense U8H is better than the TCL 6 Series/R655 2022 QLED. The Hisense has a better local dimming feature, as blacks aren't raised as much in dark scenes and there's significantly less blooming, as the local dimming feature on the Hisense dims closer to bright objects in dark scenes, whereas the TCL tends to spread the highlights out across many zones. The Hisense also has a faster response time, making it a better choice for gamers.

TCL 6 Series/R646 2021 QLED
55" 65" 75"

The TCL 6 Series/R655 2022 QLED is slightly better than the TCL 6 Series/R646 2021 QLED. HDR content looks better on the R655 thanks to its higher peak brightness and better gradient handling. The R655 is also better for gaming thanks to its higher refresh rate, and its variable refresh rate feature works better at low frame rates.

TCL 5 Series/S555 2022 QLED
50" 55" 65" 75"

The TCL 6 Series/R655 2022 QLED is a noticeable step up from the TCL 5 Series/S555 2022 QLED. The R655 gets significantly brighter and has much better reflection handling, meaning it can handle more glare in a bright room. HDR also looks noticeably better on the R655 thanks to its higher peak brightness, and bright highlights stand out better. Finally, the R655 is a much better TV for gaming thanks to its faster refresh rate and HDMI 2.1 bandwidth, allowing for 4k @ 120Hz gaming from the latest consoles.

Hisense U7H
55" 65" 75" 85"

The TCL 6 Series/R655 2022 QLED is better than the Hisense U7H. The TCL has much better reflection handling and higher peak brightness, meaning it can handle more glare in a bright room. The TCL also has much better accuracy before calibration, which is great if you care about an accurate image. Finally, the TCL is better for gaming thanks to its higher refresh rate and faster response time, resulting in much smoother motion handling and less blur behind fast-moving objects.

Test Results

Design
Design
Style
Curved No

The TCL 6 Series Roku TV has a very premium design that looks great. Instead of the simple feet found on other TCL TVs, like the TCL 5 Series/S555 2022 QLED, it has a center-mounted pedestal stand that supports the TV well. The borders of the TV are thin, but there's a noticeable dead space between the borders and the first pixels. Note that the 85" model has a slightly different design, with more traditional feet instead of the center-mounted stand.

This TV isn't part of our accelerated longevity test, but its predecessor, the TCL 6 Series/R635 2020 QLED, is.

Design
Stand

Instead of the basic v-shaped feet found on most other TCL TVs like the TCL 5 Series/S555 2022 QLED, this TV has a center-mounted pedestal stand. It's thin, so you can still place a soundbar in front of the TV, and it supports the TV well.

Footprint of the 55" stand: 11.6" x 11". The stand lifts the screen 2.8" off the table, most soundbars fit in front of it without blocking the screen.

Design
Back
Wall Mount VESA 300x300

The back has a slightly premium design. The back of the stand has a removable cover, meaning you can use it for cable management. The inputs all face to the side, but they're cut into the back of the TV, so they're somewhat hard to access when the TV is wall-mounted.

The bottom half of the screen houses all the electronics and inputs, and it's thicker than the top half. The thicker section prevents the TV from sitting completely flush against the wall if it's wall-mounted.

Build Quality

The TCL 6 Series Roku TV has good build quality. Although it's pretty much all made of plastic, it seems well-built overall. The stand is pretty solid and holds the TV in place. Unfortunately, our unit gave off a bit of a burnt-plastic smell during testing, but there were no signs of melted plastic. We've heard isolated reports of this issue with other TVs, but it's unclear if this will fade over time or if it could cause other issues.

The TCL 6 Series Roku TV has remarkable peak brightness in SDR. It's bright enough to easily overcome glare even in bright rooms. There's very little variation in brightness with different scenes, but very large, bright scenes are quite a bit dimmer than smaller highlights. Very small highlights in near-black scenes are dimmed by the TV's local dimming feature, though.

These measurements are after calibration in the 'Movie' Picture Mode with the Backlight at '100' and TV Brightness set to 'Brighter'. Local Contrast was set to 'High', Contrast was set to '100', and the Color Temperature set to 'Warm'.

Picture Quality

Backlight
Full-Array

The TCL 6 Series Roku TV has a decent full array local dimming feature. It uses a Mini LED backlight with 240 dimming zones on the 55" model. Zone transitions are a bit noticeable, even in real content. The algorithms do a good job turning on zones at the right time, but it's a bit slow to turn off zones behind fast-moving objects, so there's a noticeable bright trail in some scenes.

Despite the small size of each zone, there's still noticeable blooming, as the TV averages bright areas of the screen across more zones than necessary. Some scenes don't look as good as they should because of this, and bright highlights don't stand out as well as they should. Since the TV averages out bright highlights across multiple zones, blacks appear raised in most scenes. This results in very little black crush, which is good, as fine details in near-black scenes, like a starfield, are preserved. This also results in a bit of noticeable blooming around bright objects in dark scenes, including with subtitles.

The larger sizes of this TV have more dimming zones and likely perform a bit better. Since the TV is averaging bright highlights across a large number of zones, the TV's processing plays a bigger role in the overall local dimming performance than the number of zones.

The TV has excellent PQ EOTF tracking. Shadow details are preserved well, but near blacks are dimmed a bit. With content mastered at lower peak brightness levels, there's a sharp cutoff near the TV's peak brightness, but content mastered at 4,000 nits has a slightly smoother roll-off, so fine details are better preserved in bright scenes.

Unfortunately, there's a bit of stutter when watching low frame rate content like movies. It's especially noticeable in slow panning shots.

The TCL 6 Series Roku TV has an extremely fast refresh rate. Along with the Samsung QN95B QLED, it's one of the only TVs on the market with a 144Hz refresh rate. It also supports variable refresh rate technology, ensuring a nearly tear-free gaming experience. It works across a wide range of refresh rates, and thanks to low framerate compensation, it remains nearly tear-free even if the frame rate drops low or if you're playing a game that's locked at a low frame rate. Note that the 85" model is limited to a 120Hz refresh rate.

The TCL 6 Series Roku TV has superb low input lag, ensuring a very responsive gaming experience. The input lag is also low in 'PC' mode, which is great as you can enjoy clear text and a smooth desktop experience. Oddly, though, the input lag increases significantly when running at 144Hz.

The TCL 6 Series Roku TV supports most common resolutions, but there are a few issues. Unfortunately, the 4k @ 144Hz feature doesn't work well with all sources, as it didn't work on our test PC with an RTX 3060, but it worked fine on a different PC with an RX6600XT. It supports chroma 4:4:4 with 60Hz signals, which is important for clear text from a PC. Unfortunately, with 1080p and 1440p signals chroma 4:4:4 isn't displayed properly at 120Hz. Chroma is displayed properly with a 4k @ 120Hz signal, but you have to be in either the 'Game' Picture Mode or have Game Mode enabled; otherwise, it skips frames, resulting in a 60Hz refresh rate.

The TCL 6 Series Roku TV has an okay frequency response. Like most TVs, there's very little bass response, with no thump or rumble in its deep bass. Dialogue is very clear, even at high volume levels, but like the TCL 5 Series/S555 2022 QLED, it can't get very loud and lacks a room correction feature, so it's not a good choice for noisy environments.
