TCL C7K / QM7K 55"-85" vs Samsung The Frame 2026 (LS03H)

In terms of brightness, the models from 55 to 85 inches in the C7K series are truly impressive. In the best testing conditions, the 65-inch screen achieved over 1200 nits, which practically means that the brightest scenes can dazzle with almost cinematic brilliance. These are not just dry numbers from measurements – during screenings, white skies, explosions, or light reflections on water looked incredibly striking, often giving the impression that the television exceeds its price class. This is particularly effective in scenes with a large area of illumination, where the screen is filled with intense brightness – such as in sun-drenched shots or during dynamic action sequences. Viewers looking for strong HDR will definitely be satisfied.

However, scenes requiring precise control of backlighting – with small points of light on a dark background – are more challenging. Here the C7K, despite having over a thousand zones, can still dim brightness to maintain deep blacks. The effect is that in films like Sicario 2 or Life of Pi, some details, such as a distant lantern or single reflections, can be less defined or blend in with the surroundings. This is a compromise inherent to MiniLED technology – it provides excellent image depth and blacks at a level that ordinary LCDs do not offer, but this comes at the cost of limited visibility of the smallest lights.

The Frame 2026 is genuinely a bright TV. Its peak brightness reaches about 650 nits and, importantly, similar values are maintained regardless of the type of scene being displayed. So it doesn’t matter much whether we’re watching a very bright full-screen shot or just a small bright element occupying part of the screen. The backlight always has a lot of power, so bright portions of the image are strongly illuminated. That gives The Frame a solid foundation for HDR. Bright highlights can stand out, and the picture doesn’t look flat or too dark. Unfortunately, this is not a solution without compromises. Because it lacks local dimming, the TV cannot darken the blacks next to very bright elements.

This is clearly visible, among other things, in scenes 2 and 4 from our test procedure. Bright areas look intense, but at the same time the blacks around them become noticeably lifted. The picture loses depth as a result, especially when watching in the evening. For that reason The Frame performs best with HDR in bright and moderately bright scenes. There the high backlight brightness works in its favor. In darker shots the situation is the opposite.

Colors

The Frame also performs well in terms of color. It’s a QLED TV, so it can display a wide color gamut and show richly saturated colors. DCI-P3 coverage is around 94%, and BT.2020 about 72%. Those are good numbers and you can see them while watching. Colors are vivid and do not look washed out. It looks best in bright, colorful scenes. Animations or cartoons with lots of saturated hues can look really good on The Frame. In such material the TV shows one of its stronger points.

The novelty in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now could be found in most competitive brands. This is great news because this mode is considered the most faithful to the original vision of the creators and is often recommended by enthusiasts of good picture quality. Unfortunately – as is often the case – the mere presence of this mode does not guarantee perfection. The Filmmaker mode in the TCL C7K is not free from flaws. One could point out the incorrect white balance, particularly the slight dominance of blue, which led to cool, somewhat grayish skin tones. But that was not the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible in the gamma and EOTF charts. The image was simply too bright, at times almost blown out, which affected not only the depth of scenes but also the overall viewing experience. Some details were simply lost, and the whole image looked as if someone had slightly overdone the brightness slider. As always – we decided to see what could be squeezed out of this after calibration. And that’s when things started to get really interesting…

To evaluate the out-of-the-box colors we chose Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to present a movie or series as faithfully as possible. The TV then turns off most additional picture enhancers, and the colors and luminance characteristics are meant to be as close as possible to what the content creators intended. I have to admit that the The Frame 2026 already performs quite well in this regard straight out of the box. The biggest deviation is visible in the white balance. As brightness increases, blue starts to drop off and green increases slightly. As a result the image shifts toward warmer tones. White is therefore not perfectly neutral, and in some scenes you can notice a slightly warmer overall cast.

The luminance response — gamma or EOTF — looks good. Across most of the range they stay fairly close to the target, though in the darkest parts of the image there is a larger deviation. In practice, some details emerging from black may therefore appear a bit more pronounced. That said, it’s not a flaw that jumps out during normal viewing. Overall, Filmmaker Mode is a good starting point here. However, the factory image is a bit too warm and not all hues land exactly where they should.

After calibration, the TCL C7K showed itself in a really good light, especially when it comes to SDR content. We managed to tune the white balance, color gamut, and brightness characteristics so precisely that color errors on the ColorChecker palette dropped below a value of 2. For the uninitiated – this is almost a perfect result, which means that the image is very close to what the creators intended. Unfortunately, it looked worse with 4K HDR content. Although we were able to slightly calm the white balance and correct its previous errors, it is still evident that the television has some "MiniLED traits," especially in brightness management. When we checked how the C7K handles the EOTF curve on actual film scenes, and not just on synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This affects the overall experience – black loses some depth, and the image becomes less contrastive than it should be. Despite these minor shortcomings in HDR content, the overall reception of materials – especially in SDR – is really very good. After calibration, the C7K can display an image that can successfully compete with much more expensive models. Good color tuning, natural skin tones, and pleasant brightness make movie sessions and everyday content viewing more than satisfactory.

After calibration we mainly managed to remove that warmer cast and better even out the white balance. We also smoothed the brightness response a bit, which made the image more neutral and predictable. However, there are things calibration won't fix. It's mainly the behavior of the blacks, which stems from the backlight design itself and the lack of local dimming. In some scenes blacks will therefore still be slightly lifted, and you'll just have to accept that. That's more a characteristic of this model than something that can be fixed with settings. HDR is also somewhat limited. Samsung doesn't give full freedom to work across the widest color gamut, so not all colors can be reproduced perfectly. In normal viewing you probably won't notice it, but it's worth being aware of.

TCL C7K features a function that, according to the manufacturer, is supposed to smooth out unwanted color transitions – something like a rescue for less successful tonal changes. It's called "Gradual Smoothing" and... well, it sounds ambitious, but in practice, it works very poorly. Regardless of whether we set it to low or high, the difference is minimal. Worse still – the function can cut out elements from the image that should remain. Fortunately, film grain remains untouched, so at least it doesn't smooth everything indiscriminately, but still – it's better to just turn this option off.

When it comes to scaling lower-resolution content, it's already better. SD and HD materials look quite decent, although sometimes we felt that the image loses sharpness and becomes too soft – as if something took away its clarity. Fortunately, with very low sources (e.g., 576p), there was no overscan effect, meaning the image was not artificially cropped – everything fit on the screen as it should.

As with many of Samsung’s newer TVs, this one also uses the NQ4 AI processor, only the older, second-generation version. And you have to admit it handles digital image processing quite well. Lower-resolution material is sharpened effectively, and after upscaling to 4K it still looks natural. The TV can also somewhat "tidy up" weaker sources, like older recordings or lower-quality broadcasts. That doesn't, of course, mean it will suddenly turn poor footage into 4K, but at closer viewing distances the difference compared with simpler models with weaker processors is easy to spot. Edges are clearer, and fine details don't get lost as much to signal compression.

Samsung also offers a few additional image-enhancing features, but as usual it's best to use them sparingly. At stronger settings, noise reduction can very effectively reduce posterization, but it also noticeably interferes with the image. The picture then simply starts to look very artificial, for example by heavily smoothing characters' faces. So it makes the most sense with really poor sources when various types of noise are seriously distracting.

The TCL C7K handles motion fluency really well. The panel used in it offers a refresh rate of 144 Hz, which in itself suggests that this TV is something more than just an ordinary "60 Hz" panel. Moreover, if we connect the C7K to a computer and set the resolution to Full HD. But we'll write more about that in the paragraph about gamers and PC collaboration. Back to everyday use – both sports and movies look very good here. Thanks to the fast panel and well-functioning motion smoother, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – blur reduction and flicker reduction – which allow you to tailor the smoothness effect to your own preferences. At lower settings, we get a more cinematic effect, with a slight stutter in motion. At higher settings – the image becomes more theatrical, smooth to the point of exaggeration. Everyone can set it up according to their liking.

Samsung again used a panel with a maximum refresh rate of 144 Hz here. Refresh rates up to 120Hz primarily offer more headroom for material with a lot of motion. The TV can use additional motion interpolation systems that can improve smoothness in sports and other fast-moving content. However, a high refresh rate alone does not solve everything. The Frame still uses a VA panel, which has a relatively slow response time, and consequently fairly pronounced motion blur. With fast-moving objects, especially on a dark background, motion trails are easy to notice. There's also a slight doubling of edges, which can be visible even with the additional motion processing systems turned off. We already saw similar behavior in last year’s The Frame 2025, and it’s a pity Samsung hasn’t fixed that element. The 144 Hz itself provides a good foundation, but the panel’s response time still limits this TV.

TCL C7K is a television that on paper looks like the dream equipment for gamers – and most importantly, it holds up well in practice. First, the good news: we have two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, taking full advantage of their capabilities. The panel itself supports a refresh rate of 144 Hz, which provides a significant advantage in dynamic games. Additionally, it comes with a full suite of gaming features: VRR (variable refresh rate), ALLM (automatic low latency mode), and support for Dolby Vision in games. There's also an HGiG mode that allows for HDR effects consistent with the creators' intentions. GameBar, which is an informative bar for the gamer. It operates quickly, looks clear (like the Nintendo console👌), and shows what’s most important: the current frame count, VRR status, and even HDR parameters.

In terms of gaming features, The Frame is practically on par with Samsung's top TVs. When you connect a console the TV automatically switches to game mode thanks to ALLM, so you don't have to change settings manually each time. There's also VRR, which matches the display's refresh rate to the frames being produced by the console or PC. During drops in smoothness this helps avoid the characteristic screen tearing. The Frame of course supports 4K at 120 Hz, so you can take advantage of the PlayStation 5 or Xbox Series X in games that offer higher frame rates. HGiG also works correctly. With HDR set up properly on the console the TV doesn't try to brighten the image on its own, so bright effects in games are shown as they should be. Samsung also includes a Game Bar. It's a handy menu you can bring up without leaving the game. There you can check things like VRR and the current frame rate, and quickly change the most important gaming settings. For PC use the options are even greater, since the mentioned Full HD mode allows raising the refresh rate up to 240 Hz. There is really only one feature missing that Samsung has already spoiled us with, and that's Dolby Vision Gaming. Xbox owners will notice this the most, because that console can use Dolby Vision in games. There's one more thing worth mentioning that applies specifically to this model. Its One Connect module has only one HDMI 2.1 port, so that's the only port you can use for a console or PC if you want 4K 120 Hz. Fortunately Samsung didn't tie that port to eARC. You can therefore connect a soundbar separately (3) and still have a full HDMI 2.1 port available for the console.
