The TCL Q6/Q650G QLED is TCL's lowest-tier Q-series TV in 2023, below the TCL Q7/Q750G QLED and TCL QM8/QM850G QLED. It's a simpler TV than its more expensive siblings, so it's better suited for someone who doesn't need any advanced features or capabilities. The TV has three HDMI 2.0 bandwidth ports with variable refresh rate (VRR) support and supports TCL's Game Accelerator 120 feature for up to 1440p @ 120Hz gaming, which it achieves through resolution halving. It supports Dolby Vision HDR and HDR10+ advanced video formats and can pass through some Dolby and DTS advanced audio formats. It uses the popular and easy-to-use Google operating system. It doesn't have hands-free voice control, but its remote has an integrated microphone through which you can interact with Google Assistant and Amazon Alexa. It has built-in Chromecast, so you can seamlessly stream your shows using your phone. It's available in 4 sizes: 55, 65, 75, and 85 inches.

Our Verdict

7.3 Mixed Usage

The TCL Q6 is decent overall. It's better when you can put its extremely fast input lag to good use, like when gaming or using the TV as a PC monitor. The TV's contrast is decent but is nothing special, and it lacks local dimming to improve it further, so it's decent for a dark room, but it won't blow your socks off. Its HDR brightness is good but not enough to make highlights pop, even when combined with the TV's wide color gamut. However, its SDR brightness is very good, and it has decent reflection handling, so it's better suited as a cheap TV to put in a bright room, like a living room with windows, a bright game room, or an office.

Pros
  • Great SDR peak brightness.
  • Decent reflection handling.
  • Decent contrast ratio.
Cons
  • Poor pre-calibration color accuracy.
  • Sub-par viewing angle.
  • Doesn't have local dimming.
6.9 TV Shows

The TCL Q6 is just alright for watching TV shows. It gets pretty bright in SDR and has decent reflection handling, so it can handle bright rooms with glare, although it's best to avoid placing lights or windows directly in front of the TV. Sadly, its processing capabilities are mediocre; it does an okay job when upscaling low-resolution content. However, its low-quality content smoothing is inadequate, leading to macro-blocking when watching streaming content. The TV's viewing angle is also sub-par, so it's not great if you like to watch shows with people sitting around the TV, as they won't see a consistent image.

Pros
  • Great SDR peak brightness.
  • Decent reflection handling.
Cons
  • Sub-par viewing angle.
  • Inadequate low-quality content smoothing.
6.9 Sports

The TCL Q6 is just alright for watching sports. It gets bright in SDR and has decent reflection handling, so it looks good in bright rooms, but it's still best to avoid placing lights or windows directly in front of the TV. Its response time is decent; it's good enough for a pleasant viewing experience when watching fast-moving sports, as the resulting blur isn't annoying and won't impact your enjoyment. The TV's gray uniformity is adequate, but with certain sports with large areas of uniform color, like hockey, there is noticeable vignetting and dirty screen effect. Sadly, the TV's viewing angle is sub-par; this is not a good TV to watch the game with friends sitting around the TV at various positions, as they won't see a consistent image.

Pros
  • Great SDR peak brightness.
  • Decent reflection handling.
Cons
  • Sub-par viewing angle.
7.9 Video Games

The TCL Q6 is very good for gaming. Its contrast is decent, and its SDR brightness is great, certainly bright enough for a well-lit gaming room. For particularly bright light sources, the TV's decent reflection handling can handle some glare. Regarding performance, the TV's input lag is superbly low and fast enough for even very competitive gamers. The TV also supports 120Hz refresh rates in 1080p and 1440p through resolution halving, further lowering the input lag, which is great for gamers more worried about performance than image quality. Sadly, the TV's response time is decent, certainly satisfactory by most standards, but it introduces some blur in fast action scenes, which isn't optimal for competition.

Pros
  • Great SDR peak brightness.
  • Wide VRR range at 1080p @ 120Hz and 1440p @ 120Hz.
  • Extremely low input lag.
Cons
  • Poor pre-calibration color accuracy.
7.2 HDR Movies

The TCL Q6 is decent for watching your favorite movies. It's better when watching content from high-quality sources, like Blu-rays, as its low-quality content smoothing is inadequate, so movies from streaming platforms have noticeable compression artifacts. Thankfully, its contrast is decent, but it lacks a local dimming feature to make its blacks dark and inky. Similarly, while it looks bright enough for a pleasant viewing experience, it would benefit from local dimming to make highlights pop next to other scene elements. The TV's PQ EOTF tracking is stellar; it respects the content creator's intent. Unfortunately, this TV's color accuracy is downright poor without being calibrated, so if you care about accuracy, you need to calibrate the TV.

Pros
  • Splendid PQ EOTF tracking.
  • Wide color gamut.
  • Supports Dolby Vision HDR and HDR10+.
  • Decent contrast ratio.
Cons
  • Poor pre-calibration color accuracy.
  • Inadequate low-quality content smoothing.
  • Doesn't have local dimming.
8.0 HDR Gaming

The TCL Q6 is very good for HDR gaming. It has good HDR brightness in Game Mode and decent contrast, so it's a good TV for some dark room gaming. Its input lag is superb and even lower if you use the TV's 1080p @ 120Hz or 1440p @ 120Hz modes, although the TV achieves those numbers through resolution halving. The TV's response time is decent; it introduces some blur in fast action scenes but is satisfactory for slower and immersive HDR titles.

Pros
  • Wide color gamut.
  • Wide VRR range at 1080p @ 120Hz and 1440p @ 120Hz.
  • Extremely low input lag.
  • Decent contrast ratio.
Cons
  • Poor pre-calibration color accuracy.
  • Doesn't have local dimming.
7.7 PC Monitor

The TCL Q6 is a good TV to use as a PC monitor. Its input lag is extremely low, even when the TV is in the 'PC' Picture Mode. It has very good SDR peak brightness and decent reflection handling, so the TV can handle a bright office well. Its response time is decent overall; nothing amazing, and there's some blur when moving windows around, but it looks fine overall. However, the response time is worse in dark scenes, so avoid dark mode on your operating system and in apps for an optimal experience. Unfortunately, the TV has a sub-par viewing angle, so the sides of the screen aren't consistent with the middle when you're sitting close to the TV.

Pros
  • Great SDR peak brightness.
  • Wide color gamut.
  • Decent reflection handling.
  • Superbly low input lag even in the PC picture mode with chroma 4:4:4.
Cons
  • Poor pre-calibration color accuracy.
  • Sub-par viewing angle.

Differences Between Sizes And Variants

We bought and tested the 65-inch TCL Q6/Q650G QLED, and these results are also valid for the 55-inch, 75-inch, and 85-inch models, as the larger sizes perform roughly the same. The 75-inch and 85-inch models have different feet and back designs compared to the 55-inch and 65-inch models.

Size Model
55" TCL 55Q650G
65" TCL 65Q650G
75" TCL 75Q650G
85" TCL 85Q650G

Our unit was manufactured in June 2023; you can see the label here.

Compared To Other TVs

The TCL Q6 is a decent TV for the price and is a solid performer for what you're paying for. It's particularly interesting to gamers due to its extremely low input lag and its ability to play games at 1080p @ 120Hz or 1440p @ 120Hz with resolution halving; this is a great option for competitive gamers who care more about performance than image quality and who are on a budget. There are better buys; particularly, the TCL 5 Series/S555 2022 QLED is better and cheaper than the Q6. If you'd prefer a Hisense TV, the Hisense U6H is just as good (except for gamers) as the Q6 for a slightly lower price, and the Hisense A65K, while being just a bit worse than the TCL Q6, is also much cheaper.

For more options, check out our recommendations for the best TVs, the best QLED TVs, and the best 4k gaming TVs.

TCL Q7/Q750G QLED
55" 65" 75" 85"

The TCL Q7/Q750G QLED is better than the TCL Q6/Q650G QLED. As a higher-tier model in the same lineup, the Q7 just does more than the Q6: more gaming features, better advanced audio format support, much better contrast helped by a decent local dimming solution, and higher HDR and SDR peak brightness. The Q7 is quirkier than the Q6, but all of its quirks are in features or performance capabilities beyond what the Q6 can do.

TCL 6 Series/R655 2022 QLED
55" 65" 75" 85"

The TCL 6 Series/R655 2022 QLED is much better than the TCL Q6/Q650G QLED. The Q6 is the lowest-tier TV in TCL's 2023 Q-series lineup, while the R655 is the highest-tier model in TCL's 2022 lineup, so ultimately the R655 just does more. It has a much better contrast, helped by a decent local dimming solution. It gets much brighter in SDR and HDR and has much better color volume. The older model even comes much better calibrated out of the box than the newer one, so you have less to do to make it look its best. Ultimately, the 6 Series offers more in every context than the newer and cheaper model.

TCL S4/S450G
43" 50" 55" 65" 75" 85"

The TCL Q6/Q650G QLED significantly improves over the lower-end TCL S4/S450G. The Q6 delivers much better picture quality overall and looks better in bright rooms thanks to its higher peak brightness. HDR also looks better on the Q6 thanks to its higher peak brightness and wide color gamut. Finally, the Q6 is better for gaming thanks to the addition of VRR support, ensuring a nearly tear-free gaming experience.

TCL 5 Series/S546 2021 QLED
50" 55" 65" 75"

The TCL Q6/Q650G QLED and TCL 5 Series/S546 2021 QLED are similar TVs with different strengths and weaknesses. The 5 Series has much better contrast than the Q6, helped by its local dimming feature, which the Q6 doesn't have. However, the Q6 has better overall peak brightness in HDR. Both TVs have bad color accuracy and are tough to calibrate, although the 5 Series is even worse than the Q6.

Hisense U6K
55" 65" 75"

The TCL Q6/Q650G QLED and Hisense U6K appeal to different users. The Hisense has local dimming, so it has much deeper contrast and can emphasize bright highlights next to dimmer parts of the image. The TCL can't emphasize highlights like the Hisense, but its overall image is always bright and vibrant, although dark scenes are washed out when bright highlights are present. Unfortunately, the TCL has poor color accuracy without calibration, and it's noticeable as colors often don't look quite right. The TCL is particularly interesting for gamers on a budget, as it can do 1080p @ 120Hz and 1440p @ 120Hz with resolution halving, with a wide VRR range to match.

Hisense U6H
50" 55" 65" 75"

The Hisense U6H is better than the TCL Q6/Q650G QLED, but they're very close. The Hisense has much better contrast, helped by its local dimming feature, so it looks better in dark rooms. It gets a bit brighter than the TCL in HDR and can emphasize bright highlights better, although the TCL, in turn, is brighter in SDR. The TCL offers more to gamers, with the option of playing in 1080p @ 120Hz or 1440p @ 120Hz with resolution halving and a matching VRR range. But of the two, the Hisense is the easiest TV to buy, install, and watch due to its vastly better pre-calibration color accuracy than the TCL.

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

The TCL 5 Series/S555 2022 QLED is better than the TCL Q6/Q650G QLED. The 5 Series has vastly better contrast, helped by its local dimming feature, which the Q6 doesn't have. It can reach higher peak brightness in HDR and SDR than the Q6, so it emphasizes bright highlights better than the newer model can, although it comes at the cost of more brightness variation on a scene-by-scene basis. The Q6 does offer more to gamers, however, with a wider choice of available resolutions. That said, the 5 Series is vastly more color-accurate pre-calibration; you can buy that TV and start watching it without worrying about calibration, unlike the Q6.

Hisense A65K
43" 50" 55" 65" 75"

The Hisense A65K and TCL Q6/Q650G QLED are similar TVs, although the TCL is slightly better than the Hisense. The TCL is brighter than the Hisense and offers more to gamers with the option of playing in 1080p @ 120Hz or 1440p @ 120Hz with resolution halving and a matching VRR range. The Hisense, however, is much more accurate even without being calibrated; it's a TV that you can just buy, install, and watch, while the TCL requires a fair amount of work to look its best, especially if you care about color accuracy.

The TCL 65Q650G has a set of plastic feet, which you can place at two distinct positions. The first position, pictured above, sets the feet in a wider position and has a footprint of 53.8" x 14.1". The narrow position puts the feet closer to the TV's center and lets you put the TV on smaller tables. In this position, the feet have a footprint of 36.9" x 14.1". The screen sits about 2.7" from the table, so some slimmer soundbars fit under it, but it's a tight fit. In the narrow position, the protruding feet get in the way of putting a soundbar directly in front. Note that the 75-inch and 85-inch models have different feet than the 65-inch model.

Design
Back
Wall Mount VESA 300x300

The back of the TV is a mix of metal and plastic. The TV's back has two distinct parts: the plastic bottom part, which protrudes from the back and hosts the inputs and power connection, and the thinner metallic upper portion. The metal is rigid and untextured, while the thick textured plastic on the bottom part has a lot of flex to it when you press on it. It's not worrying and feels normal for a budget TV.

The power cable comes out of the right side of the TV, while the inputs are on the left side. There are clips on both sides to help with cable management. The side-facing inputs are hard to reach without pulling the TV slightly forward when the TV is wall-mounted. Only the 55" and 65" models have this back; the 75" model has a more unified back panel with a slightly sloping upward section, while the 85" model has a different two-part back.

The TV has okay build quality. There's minimal flex in the metallic upper section of the back, but there's a fair amount of it in the bottom, thicker plastic section, although it's not worrying. The TV wobbles a bit on its feet, but again, nothing worrying.

Our unit has a pinch in the front lower right of the screen, which is noticeable in dark scenes. This could have happened during shipping, so it doesn't affect the build quality of this particular TV.

The TV has decent contrast. Its native contrast is excellent, so blacks are deep and true in dim and dark scenes. Since it lacks a local dimming feature, blacks are raised and appear washed out when very bright highlights appear on the screen. If you'd prefer something with better contrast, look up the Hisense U6K.

The TV has good HDR peak brightness. There's no variation in brightness between different scenes regardless of highlights, which is great, but it also means that bright highlights are not emphasized next to other elements of the scene. Still, the TV is bright enough to overcome glare in a bright room.

The TV has fantastic PQ EOTF tracking. Aside from significantly raised blacks and near-blacks, the TV's brightness closely follows the curve, so it tracks the content creator's intent well. There's a sharp cutoff with content mastered at 600 and 1,000 nits, leading to a loss of bright detail. It tone maps better with content mastered at 4,000 nits, preserving more fine details in really bright content.

The TCL Q6 has poor pre-calibration accuracy. Its white balance is terrible, with significant accuracy errors throughout every range of gray except blacks. The TV's gamma is overbrightened compared to the reference target of 2.2 for a moderately lit room. The TV's color accuracy is okay; saturated colors are accurate, but undersaturated colors show a fair amount of accuracy errors. Thankfully, the TV's color temperature is spot on the 6500K target, so it has neither a red nor blue tint.

The TCL Q6 has decent gray uniformity, especially on a very dark or near-black screen, where its uniformity is great. On brighter uniform colors, there's significant vignetting, banding, and dirty screen effect near the center of the screen. This is noticeable in certain content, like hockey with its all-white rink, as the sides and corners of the scene are noticeably darker than the rest.

The TV has inadequate low-quality content smoothing. While its detail preservation is decent, there's significant macro-blocking in dark scenes.

Picture Quality
Upscaling: Sharpness Processing

The TV has barely adequate upscaling capabilities. It manages to preserve some details, and text is clear enough, but upscaled content looks a bit muddy overall.

Sharpness processing was calibrated for low-resolution or low-bitrate content, with no over-sharpening, with the following setting:

  • Sharpness: 12

The TV uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional RGB layout. It doesn't cause any issues for video content, but if you plan to use this TV as a PC monitor, non-RGB subpixel layouts impact text clarity, and text looks slightly blurry. You can read about it here.

The TCL Q6 has a decent response time. It does struggle a bit more when coming out of dark states, so there's some black smearing in dark transitions. The TV doesn't have the response time quirks of the TCL Q7/Q750G QLED or TCL QM8/QM850G QLED when VRR is enabled.

PWM Dimming Frequency

The TCL Q6 uses pulse width modulation (PWM) to dim its backlight, and it flickers at 150Hz, which is low enough to be noticeable by users who are sensitive to it, especially as it doesn't flicker in time with the TV's refresh rate. Fortunately, the TV is flicker-free at these brightness levels and picture modes:

  • Movie, with brightness levels 26-100
  • Low Power, with brightness levels 60-100
  • Sports, Game Mode, and PC, with brightness levels 28-100
  • Smart HDR, always flicker-free

The TCL Q6 has a motion interpolation feature to interpolate 30 fps content up to 60 fps. As typical of this feature, it looks fine with slow scenes, but there are noticeable artifacts with fast-moving objects.

Due to this TV's only decent response time, it does a good job with stutter in movies. It's particularly fantastic with 60 fps content. It's only okay with 24 fps content, like movies, but you can compensate for this by enabling some of the TV's motion interpolation features, although that introduces other issues.

This TV supports every variable refresh rate (VRR) technology for a nearly tear-free gaming experience. The TV's VRR range is narrow at 4k, but when running at 1080p @ 120Hz or 1440p @ 120Hz, with resolution halving, the VRR range is much wider; great for competitive gamers who prefer a higher refresh rate and lower input lag over better visuals.

The TV supports all common resolutions up to 4k @ 60Hz. Even though the TV has a 60Hz panel, it can do 1080p @ 120Hz and 1440p @ 120Hz with resolution halving through TCL's Game Accelerator 120 feature. This impacts image quality as the TV halves the display's 4k vertical resolution to run at 120Hz. Still, it's a great option for competitive gamers who prefer having a higher refresh rate and lower input lag over better visuals.

The TV can't take full advantage of the PS5, as it can't do 4k @ 120Hz. However, it can do 1080p @ 120Hz and 1440p @ 120Hz with resolution halving. Unlike on the Xbox consoles, the TV has no issues playing HDR games in 120Hz on the PS5.

It also supports VRR and Auto Low Latency Mode (ALLM), so the TV automatically switches to Game Mode when it detects the console.

Note that when launching a Dolby Vision or HDR game at these resolutions, the console automatically sets itself to 4k @ 60Hz, as the Xbox only supports HDR with 4k content.

The TV also supports VRR and Auto Low Latency Mode (ALLM), so the TV automatically switches to Game Mode when it detects the console.

The TCL Q650G supports eARC, allowing you to pass high-quality, uncompressed audio to a compatible receiver. While the TV can pass DTS 5.1 through ARC and Optical connections, it can't pass the full 7.1 DTS:X or DTS-HD formats through eARC, which is disappointing as many UHD Blu-ray discs use these as their main audio track. However, it can pass Dolby advanced audio formats through eARC.

The TV has a middling frequency response. TVs tend to have awful bass, and this TV is no different; there's no thump and rumble at all. That said, the TV gets pretty loud and has surprisingly little pumping or compression artifacts at max volume. Otherwise, it doesn't sound great, with inaccurate sound reproduction across the board.

This TV's handling of sound distortion is decent. Sound is distorted at max volume, which sounds unpleasant, especially if you're sensitive to it. At lower volumes, however, it sounds good, and it's hard to notice any harsh or unexpected frequencies when listening at moderate volume levels.
