TCL Q6/Q650G QLED TV Review

The TV has a simple look: it's not overly slim, and it's good-looking without drawing too much attention to itself.

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 inches 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 and 85-inch models have different feet than the 65-inch model.

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. That said, it isn't 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 it slightly forward when it's wall-mounted. Only the 55 and 65-inch models have this back; the 75-inch model has a more unified back panel with a slightly sloping upward section, while the 85-inch 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 that's typical. It 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. However, 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 U6/U6K or Roku Plus Series QLED.

This TV doesn't have a local dimming feature, so there's no blooming around bright objects or subtitles in dark scenes. As the TV can't brighten highlights without impacting the rest of the image, dark scenes look washed out.

It doesn't have a local dimming feature, so it can't adjust the backlight of individual areas to brighten up highlights without impacting the rest of the image. This means that there are no distracting flickers or brightness changes as bright highlights move between dimming zones.

Switching to Game Mode doesn't result in any noticeable difference in dark scene performance, which is great.

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.

These measurements are after calibrating the HDR white point with the following settings:

• HDR Picture Mode: Movie
• Contrast: 100
• Brightness: 100
• Color Temperature: Warm -5

The TV's HDR brightness in Game Mode is good. There's no noticeable difference in peak brightness from 'Movie' mode.

These measurements are after calibrating the HDR white point with the following settings:

• HDR Picture Mode: Game
• Brightness: 100
• Contrast: 100
• Color Temperature: Warm -5

The TV has fantastic PQ EOTF tracking. Aside from significantly raised blacks and near-blacks, the TV's brightness closely follows the target 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. Its tone maps better with content mastered at 4,000 nits, preserving more fine details in really bright content.

The TV's SDR peak brightness is great. It gets bright enough to fight glare in bright rooms, and there's no variation in brightness between content.

These measurements are after calibration with the following settings:

• Picture Mode: Movie
• Brightness: 100
• Contrast: 96
• Micro Contrast: Off
• Gamma: 2.2
• Black Level: 50
• Dynamic Contrast: Off
• Black Stretch: Off
• Dynamic Brightness: Off

The TCL Q6 has a great color gamut. It has fantastic coverage of the commonly used DCI-P3 color space, although its greens and yellows are undersaturated. The TV adequately covers the wider, but not as common, Rec. 2020 color space.

The TCL Q6 has decent color volume in HDR. However, it struggles to represent dark colors and bright, saturated greens and yellows.

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 TV's accuracy after calibration is fantastic. Colors and white balance errors are significantly improved, and the gamma is better overall, though bright scenes are overly darkened. 

The TV is hard to calibrate, though. When adjusting settings, they sometimes don't affect anything, and then suddenly, you have moments where an adjustment impacts settings it shouldn't, so you need to constantly re-adjust your calibration to compensate.

See our full calibration settings.

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 TCL Q6's black uniformity is incredible, although there's some noticeable backlight bleed near the TV's bottom edge. There's no local dimming feature, so the entire screen is blueish and cloudy when bright highlights are on the screen.

The TV's viewing angle is sub-par and isn't a good choice for wide seating arrangements. There's significant color shifting and brightness loss as you move off-center, and the image looks increasingly washed out as you move further away to the sides.

The TV's reflection handling is decent. It does an excellent job with indirect reflections, like glare from a light source that isn't directly facing the screen. With direct reflections from sources placed directly in front of the screen, the reflections are noticeable when watching content.

The TCL Q6 has decent HDR gradient handling. There's very noticeable banding in dark grays and noticeable banding in dark reds, greens, and blues, but other color gradients have minimal banding.

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

The TV does an inadequate job of upscaling low-resolution content like DVDs or lower-resolution streams. Details are very soft, and finer details are incredibly hard to make out.

Sharpness processing was calibrated with no over-sharpening for low-resolution content 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. 

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. Thankfully, the TV doesn't have the response time quirks of the TCL Q7/Q750G QLED or TCL QM8/QM850G QLED when VRR is enabled.

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

This TV doesn't have an optional backlight strobing feature, commonly known as black frame insertion (BFI).

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.

The TCL Q6 QLED removes 24p judder from 24p signals, like a blu-ray player, and from native sources, but it can't properly remove judder from 60Hz sources.

This TV supports every variable refresh rate (VRR) technology for a nearly tear-free gaming experience. Its 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 has superbly low input lag in Game Mode. It's equally as good in the TV's 'PC' Picture Mode, which you need to set it at to get chroma 4:4:4 support for clear text when using the TV as a PC monitor.

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.

The TV can't take full advantage of the Xbox Series X or S, as it can't do 4k @ 120Hz. However, it can do 1080p @ 120Hz and 1440p @ 120Hz with resolution halving. 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.

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

This TV is limited to HDMI 2.0 bandwidth on its three HDMI ports and supports HDR10+ and Dolby Vision. The tuner is limited to ATSC 1.0, so you can't stream 4k content over the air.

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.

If you want a similar TV with DTS audio support, take a look at the 2024 TCL Q6/Q651G QLED.

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.

The TV uses version 11 of Google's popular Google TV OS. It's relatively easy to use and runs well, with a large selection of apps.

Like most TVs on the market, this TV has ads throughout the interface, and you can't disable them.

It has a great selection of streaming apps, with every popular streaming app being present. The interface is very smooth and pleasant to use.

The TV's remote is medium-sized and has a simple layout. It has a series of dedicated buttons for the most popular streaming apps. The remote has an integrated microphone for voice commands, and these work pretty well; you can change inputs, search within apps, and ask for the weather.

The power button is on the bottom bezel of the TV below the TCL branding. Outside of turning the TV on or off, you can also use it to change channels, the volume, or the inputs.
