The TCL QM6K is an entry-level TV released in 2025 and technically replaces the 2024 TCL Q6/Q651G QLED, although the newer model is a step up from the previous one due to its Mini LED panel and advanced gaming features, but at a higher cost. It supports both 4k @ 144Hz and 1080p @ 288Hz, with VRR, on its two HDMI 2.1 ports. It also has two HDMI 2.0 ports, one of which doubles as an eARC port with full Dolby and DTS advanced audio passthrough. The TV supports both Dolby Vision HDR and HDR10+ formats and runs version 12 of the popular Google TV smart interface, so it also has smart features like voice control and is loaded with a ton of streaming apps. We bought and tested the 75-inch model, but it's available in six sizes total: 50, 55, 65, 75, 85, and 98-inches.
Our Verdict
The TCL QM6K is a well-rounded TV, even if it doesn't excel in any particular area. Its strongest suit is its very good gaming performance, helped by its very low input lag, high refresh rate support, and numerous gaming features. Visually, the TV doesn't impress, although its black levels are quite good due to its impressive contrast and good black uniformity. Unfortunately, there's more blooming around bright highlights than you'd like, but it's alright. Its HDR brightness is mediocre at best, so the TV doesn't provide an impactful HDR experience overall. Still, it's a decent choice for reference conditions due to those black levels, good HDR brightness accuracy, and low amount of stutter. It performs better in SDR content due to its high SDR peak brightness, which is enough to overcome some glare from brighter rooms, just as long as you avoid placing any lights directly facing the TV.
Very good black levels deliver deep blacks no matter the room context.
Very accurate in HDR and SDR.
Bright enough in SDR to overcome glare from indirect light sources.
HDMI 2.1 bandwidth, up to 4k @ 144Hz and 1080p @ 288Hz, and VRR support.
Too dim in HDR to provide a truly impactful HDR viewing experience.
Visible glare when placed directly opposite bright lights or windows.
Image degrades somewhat when viewed from extreme angles.
The TCL QM6K is a decent choice for a home theater setup, mostly due to its good black levels. Its contrast is impressive, and its black uniformity is good, so it delivers deep blacks in darker scenes, even if there's a bit more blooming around bright highlights than you'd like. Aside from that, the TV is decent but unimpressive. Its HDR color volume is alright and does the job, but colors aren't vibrant, although they're accurate. The TV is not nearly bright enough in HDR to deliver impactful HDR highlights. The TV's PQ EOTF tracking is quite good, however, so the TV mostly follows the content creator's intent when it comes to HDR brightness. There's also little noticeable stutter due to the TV's relatively slow response time.

The TCL QM6K is a decent choice for brighter rooms due to its good SDR brightness, which is high enough to overcome some glare in well-lit contexts. Unfortunately, the TV struggles with direct reflections, so it doesn't fare well in rooms with tons of lights directly facing it. The TV's colors are decent, but they're not impactful even if they are mostly accurate. Thankfully, the TV's black levels don't noticeably raise in brighter rooms.
Bright enough in SDR to overcome glare from indirect light sources.
Visible glare when placed directly opposite bright lights or windows.
The TCL QM6K is a satisfactory choice for sports. It's bright enough in SDR to overcome glare from brighter rooms but make sure that your lights aren't directly facing the screen as the TV struggles with direct reflections. Its image processing is decent, so it cleans up a bit of macro-blocking when you're watching sports through streaming services, although its upscaling doesn't quite manage to significantly clean up low-resolution content. Its colors are quite accurate in SDR, so your favorite team's jerseys look as they should, although the TV's SDR color volume isn't good enough to make them pop out of the screen. Its viewing angle is mediocre, so it's not the best choice for a wide seating arrangement; try to keep your friends seated directly in front of the TV for the best possible experience.

The TCL QM6K's color is decent overall, mostly because of its strong color accuracy, especially in HDR. This isn't really a TV that most purists will feel pressed to get calibrated. Its color volume, however, is just alright in SDR and HDR. It's good enough for most people, but colors don't pop out of the screen.
Very accurate in HDR and SDR.
Note: We're in the process of improving our tests related to image processing, but this score should give you a general idea of how a TV performs overall with its image processing capabilities.
The TCL QM6K's image processing is decent overall. It mostly respects the content creator's content when it comes to its HDR brightness, even if most of it is a bit too bright overall. It cleans up low-bitrate content well enough, but there's still some noticeable macro-blocking. It doesn't do quite as good of a job with low-resolution content; it ends up looking a bit muddy when upscaled. Its HDR native gradient handling is alright, but there's some noticeable banding in some color gradients.
Follows the content creator's intent relatively well, if a tad overbrightened overall.
The TCL QM6K is quite responsive in Game Master. Its input lag is extremely low at any of its refresh rate modes. The TV supports 4k @ 144Hz but also 1080p @ 288Hz through TCL's Game Accelerator feature, a boon for any hardcore competitive player who wants to get the highest refresh rate possible from their TV. There's a wide VRR range, even at 288Hz, providing a mostly tear-free gaming experience. Its pixel transitions are decent at the faster refresh rates, although it's not quite as good at 60Hz. Still, overall, the transitions are fast for an LED TV.
Extremely low input lag.

Popular TV Comparisons
The TCL QM6K is a decent product, as it's rather well-rounded. Still, it falls in a similar price bracket to the TCL QM7/QM751G QLED and the Hisense U7N, both of which are much better than the QM6K, especially the QM7. They're both far brighter and more colorful overall, with better image processing, even if the QM6K has better black levels than the Hisense. Still, the QM6K serves as a solid LED gaming TV due to its advanced gaming features, relatively fast pixel transitions, and up to 1080p @ 288Hz support.

The TCL QM751G is better than the TCL QM6K in almost every way, as the QM7 is brighter, has better black levels, has better image processing, and is more colorful overall, delivering a more impactful viewing experience. The QM6K is, however, more accurate and follows the content creator's intent more closely than the QM7K51G does. It's also capable of gaming at 1080p @ 288Hz, while the QM751G tops out at 1080p @ 240Hz.
The TCL QM7K is better than the TCL QM6K. The QM7K is brighter, has much better contrast, and is more colorful than the QM6K, delivering a much more impressive experience overall. The QM6K is, however, more accurate, but it doesn't do much to offset the QM7K's performance advantage.
The Hisense U7N is mostly better than the TCL QM6K. The Hisense is brighter and more colorful overall, alongside having better image processing, delivering a generally more impactful viewing experience, even with the TCL's better black levels. The TCL does have some advantages, as it's more accurate, and has faster pixel transitions, alongside more gaming features than the Hisense.
The Hisense U8N is noticeably better than the TCL QM6K. The Hisense is considerably brighter, with deeper black levels and more vibrant colors, giving it a clear edge in image quality. Still, the TCL is much more accurate out of the box and offers better HDR brightness accuracy, so purists will want to calibrate the Hisense. Overall, the Hisense has superior image processing and reflection handling, further reinforcing its advantage over the TCL in most respects.
Test Results
The TCL QM6K has just mediocre HDR brightness. While it performs well in test slides, in real content its brightness is inadequate, so it can't display bright highlights with any real impact.

The TV's SDR brightness is good, and it overcomes some glare when watched in brighter rooms.
The TCL QM6K has impressive contrast. Its native contrast is very good, but with Local Contrast set to 'Low,' the TV displays very deep blacks that stay deep even when bright highlights are on screen. It has much deeper blacks than many other similarly priced models, such as the Samsung Q7F 2025.
The TV's lighting zone precision is alright. There's visible blooming around bright highlights or text when they're against a black background, making blacks look less deep.
The TV has decent lighting zone transitions. Still, there is some visible darkening on the leading edge of bright objects, with noticeable haloing.
There's no visible difference in dark scene performance when the TV is set to Game Master.
The TV's black uniformity is good, although there's noticeable blooming around bright highlights when local dimming is enabled. With local dimming disabled, the screen is more uniform, yet blacks are noticeably raised, although corners are brighter than the rest of the screen.
The TV's SDR color volume is okay. It lacks the color volume in DCI-P3 to fully display any color, but it's decent overall. However, the TV's color volume is middling in the BT.2020 color space; it struggles with fully displaying almost all colors, especially lighter colors outside of those close to pure white.
| Volume ΔE³ | DCI-P3 Coverage | BT.2020 Coverage |
|---|---|---|
| L10 | 88.67% | 66.49% |
| L20 | 88.61% | 65.09% |
| L30 | 89.31% | 65.64% |
| L40 | 87.27% | 65.40% |
| L50 | 85.84% | 64.43% |
| L60 | 83.88% | 61.32% |
| L70 | 81.07% | 52.24% |
| L80 | 80.21% | 49.46% |
| L90 | 80.13% | 49.85% |
| L100 | 84.72% | 63.52% |
| Total | 83.71% | 57.93% |
The TCL QM6K's HDR color volume is alright. Dark saturated colors are displayed well due to the TV's impressive contrast. Unfortunately, it struggles with displaying any bright colors due to its relatively low HDR brightness, and its overall color volume isn't as good as the Hisense U65QF.
The TCL QM6K's SDR pre-calibration accuracy is good. Its color accuracy is impressive, as most colors are on target, with only some color mapping errors in saturated reds, magentas, blues, and whites.
Unfortunately, its white balance is just mediocre, as reds and blues are overrepresented in most grays, more so for reds in brighter grays, while greens are slightly underrepresented in all grays. Thankfully, this doesn't negatively impact the TV's color temperature, as it's almost perfectly on target. As for gamma, darker scenes are too dark, while brighter ones are too bright, although most scenes veer slightly on the bright side.
The TV's SDR image accuracy is fantastic after calibration. White balance is now almost perfect, with no noticeable impact on the already outstanding color temperature. Color accuracy is also vastly improved, as only darker blues still have color mapping issues.
You can see our full calibration settings.
The TCL QM6K's HDR pre-calibration accuracy is great. Color temperature is very close to the 6500K target even if blues are overrepresented in brighter grays, while reds are slightly underrepresented in the same grays. Color accuracy is excellent, although blues, reds, and magentas deviate from what they should be.
The TV's HDR accuracy after calibration is fantastic. White balance is now excellent, and color accuracy is fantastic. Colors are now mostly on target, although there are still some minor color mapping issues in blues and reds. Color temperature is now perfectly on target.
The TCL QM6K has good PQ EOTF tracking. All mastered content is initially slightly too dark, more so for content mastered at 1000 and 4000 nits, but it's then slightly too bright for the rest of the curve. There's a roll-off near the TV's peak brightness to maintain details in highlights in all mastered content.
The TV's low-quality content smoothing is decent. It does a satisfactory job at removing macro-blocking from low-bitrate content, but there is some loss of detail in the process.
The TV does an alright job at upscaling low-resolution content like DVDs or lower-resolution streams. Details are somewhat clear, but finer details are noticeably hard to make out.
The TV's HDR native gradient handling is alright. There's noticeable banding in all grays and greens and in darker reds, but other color gradients have minimal banding.
The TV has very low input lag at all resolutions and refresh rate combinations when set to Game Master.
The TV supports all common resolutions up to 4k @ 144Hz on two of its four HDMI ports.
The TV supports all three types of variable refresh rate (VRR) technology to reduce screen tearing. Its VRR range caps out at 144Hz or 288Hz, depending on the resolution.
The TV's CAD at its maximum refresh rate is decent. There's a fair amount of overshoot when transitioning from black or dark shades to a brighter one, causing inverse ghosting. Still, overall, it provides consistent performance without excessive motion blur.
The TV's CAD at 120Hz is okay. Much like at its maximum refresh rate, it has some overshoot when going from a completely black frame to a dark gray shade, leading to inverse ghosting.
The TV's CAD at 60Hz is mediocre. There is no overshoot here, but unfortunately, most transitions are quite slow, leading to noticeable motion blur.
The TV is fully compatible with everything the PS5 offers, like 1440p @ 120Hz and 4k @ 120Hz, as well as HDMI Forum VRR. It also supports Auto Low Latency Mode, so you don't have to worry about manually switching to Game Master to get the lowest input lag.
The TV is fully compatible with everything the Xbox Series X|S offers, including 1440p @ 120Hz, 4k @ 120Hz, HDMI Forum VRR, FreeSync Premium Pro, and Dolby Vision gaming. It also supports Auto Low Latency Mode, so you don't have to worry about manually switching to Game Master to get the lowest input lag.
Due to the TV's relatively slow response time, there isn't much stutter when watching movies or TV shows, although you'll notice some if you're particularly sensitive to it.
The TCL QM6K automatically removes judder from 24Hz sources and the internal apps. To remove judder from 60p and 60i sources, like a cable box, Motion Clarity needs to be set to 'On' with sliders set to '0.'
The TCL QM6K has an okay response time. It really struggles when going from bright shades to many darker shades and from a completely black screen to a near-white one. This leads to noticeable motion blur in a wide variety of content, but it also means that the TV doesn't have a ton of stutter when watching movies.
The TCL QM6K uses pulse width modulation (PWM) to dim its backlight. Fortunately, it flickers at an incredibly fast 10,400Hz in all picture modes and at all brightness levels, so it's not noticeable.
The TCL QM6K TV has an optional backlight strobing feature, commonly known as black frame insertion. This feature is meant to reduce persistence blur and improve the appearance of motion. It works at both 60Hz and 120Hz, albeit with some obvious image duplication. Note that enabling this feature reduces the panel's overall brightness.
This TV has an optional motion interpolation feature to improve the clarity of motion, but it doesn't work very well. Even slower-moving scenes have some noticeable artifacts present. It really struggles with faster-moving scenes, as the interpolation seems to stop when the action gets too hectic, causing distracting artifacts.
The TCL QM6K has poor direct reflection handling. It barely reduces the intensity of direct light sources like a lamp placed opposite the screen, which is very distracting.
Black levels barely raise on this TV in a room with ambient lighting, so you still get deep blacks regardless of your lighting conditions.
The total reflected light of this TV is alright. Reflections are visible on this TV during dark scenes, and there's some distracting light banding, although it's not extremely noticeable.
The TV has okay color saturation in a bright room, but there's some color degradation in well-lit contexts.
The TV has a mediocre viewing angle, so it's not suitable for a wide seating arrangement. Its biggest weaknesses are its gamma shifting and raised black levels at an angle, so colors look off and washed out as you move further away to the sides, although the colors stay mostly accurate.
The TV has okay gray uniformity, but there's a noticeable grid-like pattern in the lower right portion of the screen, which is visible in some moving content.
The TV uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional RGB layout. For video or gaming content, this doesn't cause any issues, but for PC monitor use, it can be a problem as it impacts the text clarity, although not everyone will notice this.
The TV uses a KSF phosphor coating to produce red light, with high peaks on reds and blues. This model does have good separation between colors, giving it solid color purity and a wide color gamut.
The TCL QM6K has HDMI 2.1 bandwidth on HDMI ports 1 and 2, with both supporting up to 4k @ 144Hz. HDMI 4 has eARC but is limited to HDMI 2.0 bandwidth, which is nice as you're not losing on an HDMI 2.1 port when you connect a soundbar to the TV. Unfortunately, the TV doesn't support ATSC 3.0, so over-the-air broadcasts are limited to 1080p.
The TV supports eARC, which lets you pass high-quality, uncompressed audio to a compatible receiver or soundbar through an HDMI cable. It supports all major audio formats, so you don't have to worry about compatibility with external sources.
The TCL QM6K has a nice overall design, even if it's mostly made of plastic, including its adjustable feet.
The two feet are made of plastic and can be placed in two distinct positions. In the wider position, the footprint of the 75-inch stand is 56.7" x 13.4", while it's 28.3" x 13.4" in the narrow position.
The feet lift the TV about 3.5 inches above the table, so almost any soundbar fits underneath.
The back of the TV is made of plastic. All of the inputs except for the power connector are located on the right side of the TV when facing the front, and they're easy to access if you have the TV wall-mounted. The TV has clips on the back for cable management.
The TV has decent build quality. The back is made of plastic and flexes quite a bit near the middle, but it's not worrying.
Unfortunately, like almost all TVs on the market, the smart interface contains ads, and you can't disable them.
There's a single button on the bottom middle of the TV that you can use to switch inputs and power the TV on/off. There's also a small switch that you can use to turn on/off the TV's built-in microphone.
The TV has an okay frequency response. It has sub-par bass and has some compression artifacts when running the volume at or close to maximum, which is rather low, so this isn't a good TV to listen to in noisy rooms. However, when listened to at low to moderate volumes, the TV sounds good, and the dialogue is easily understood.
