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

In terms of brightness, the models ranging from 55 to 85 inches in the C7K series are truly impressive. Under the best testing conditions, the 65-inch screen reached over 1200 nits, which in practice means that the brightest scenes can shine with almost cinematic brilliance. These are not just dry numbers from measurements – during viewings, the white skies, explosions or reflections of light on water looked extraordinarily striking, often giving the impression that the television exceeded its price class. This is particularly effective in scenes with large areas of brightness, where the screen is filled with intense light – such as in sunlit shots or during dynamic action sequences. Viewers seeking strong HDR will definitely be satisfied.

However, scenes that require precise control of the backlighting – with small points of light on a dark background – prove to be more challenging. Here, the C7K, despite having over a thousand zones, still dims the brightness to maintain deep blacks. The effect is that in films like Sicario 2 or Life of Pi, some details, like a distant lantern or single reflections, can be less distinct or blend into the surroundings. This is a compromise inherent in 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 finest lights.

The Frame 2026 is a genuinely bright TV. Its peak brightness reaches around 650 nits and, importantly, it maintains similar levels regardless of the type of scene being displayed. It doesn’t really matter whether we’re watching a very bright full-screen image or just a small highlight occupying part of the screen. The backlight remains powerful, allowing bright parts of the image to stand out clearly.

This gives The Frame a solid foundation for HDR. Bright highlights can look impactful, and the picture doesn’t appear flat or overly dim. Unfortunately, there is a compromise. Without local dimming, the TV cannot darken the black areas surrounding very bright objects.

This is clearly visible in scenes 2 and 4 of our test procedure. Bright elements look impressive, but at the same time, the blacks around them become noticeably raised. As a result, the image loses some of its depth, especially when watching in a dark room. This is why The Frame performs best with HDR in bright and moderately bright scenes, where its high brightness works to its advantage. In darker scenes, the situation is quite the opposite.

Colours

The Frame also performs well when it comes to colour reproduction. As a QLED TV, it can display a wide colour gamut and produce rich, saturated colours. DCI-P3 coverage reaches around 94%, while BT.2020 comes in at around 72%. These are good results, and you can see the difference in actual content.

Colours look vivid without appearing washed out, particularly in bright and colourful scenes. Animations and other content with plenty of saturated colours can look really good on The Frame. With this type of material, the TV shows one of its stronger sides.

A new feature in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now could be found in most competing brands. This is great news, as this mode is considered the one that most accurately represents 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 it does not guarantee perfection. The Filmmaker mode in the TCL C7K is not without its flaws. One can point out the incorrect white balance, particularly the slight dominance of blue, which resulted in cool, somewhat greyish skin tones. But that was not the biggest issue. The main complaint was excessive brightness exposure, which was clearly visible on gamma and EOTF charts. The image was simply too bright, at times even overexposed, which affected not only the texture of the scenes but also the overall viewing experience. Some details were simply lost, and the entire image looked like someone had slightly overdone the brightness slider. As always, we decided to see what could be squeezed out of it after calibration. And that’s where it started to get really interesting…

For assessing the factory colour output we chose the Filmmaker Mode. If you’re encountering it for the first time, it’s a mode designed to reproduce a film or series as faithfully as possible. The TV then switches off most of the extra picture enhancement features, and the colours and luminance characteristics are intended to be as close as possible to what the creators of the material intended. And it must be admitted that The Frame 2026 performs really well in this respect straight out of the box. The biggest deviation is visible in the white balance. As brightness increases the blue starts to drop out and green increases slightly. As a result the picture shifts toward warmer tones. White is therefore not perfectly neutral, and in some scenes you can notice a slightly warmer cast.

The luminance response for both the gamma and EOTF curves looks good. Across most of the range they stay fairly close to the target, although in the darkest parts of the picture there is a larger deviation. In practice some details emerging from black may therefore be rendered a little more strongly. However, this is not an error that stands out during normal viewing. Overall Filmmaker Mode is a good starting point here. However the picture is a little too warm by default and not all hues land exactly where they should.

After calibration, the TCL C7K presented itself in a really good light, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics so that the colour errors on the ColorChecker palette fell below a value of 2. For the uninitiated – this is nearly a perfect result, indicating that the image closely resembles what the creators intended. Unfortunately, it looked worse with 4K HDR content. While we slightly managed to calm the white balance and correct its previous errors, it still shows that the TV has some “MiniLED traits”, particularly in brightness management. When we checked how the C7K copes with the EOTF curve on real film scenes, rather than just synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This affects the overall impression – the black loses some depth, and the image becomes less contrasty than it should be. Despite these minor shortcomings in HDR content, the overall reception of materials – especially in SDR – is truly very good. After calibration, the C7K is capable of displaying an image that can successfully compete with much more expensive models. Good colour tuning, natural skin tones, and pleasant brightness ensure that movie sessions and everyday content viewing are more than satisfactory.

After calibration we mainly managed to remove that warmer tint and better even out the white balance. We also smoothed the brightness response a little, which made the picture more neutral and predictable. There are, however, things calibration won't fix here. It's mainly the black behaviour, which stems from the backlight design and the lack of local dimming. In some scenes blacks will therefore still be slightly lifted and you simply have to accept that. It's more a characteristic of this model than something that can be fixed with the settings. HDR is also a limitation. Samsung doesn't allow full freedom when working with the widest colour gamut, so not all colours can be reproduced perfectly. In normal viewing it's probably hard to notice, but it's worth being aware of.

The TCL C7K features a function that, according to the manufacturer, is designed to smooth out unwanted colour transitions – a sort of rescue for less successful tonal shifts. 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. What's worse, the function can cut out elements from the image that should remain. Fortunately, the film grain remains untouched, so at least it doesn't smooth everything indiscriminately, but still – it's better to simply turn this option off.

When it comes to scaling lower resolution content, it’s much better. SD and HD materials look quite decent, although at times we had the impression that the image was losing sharpness and becoming too soft – as if something was detracting from 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 smoothness really very well. The matrix used in it offers a refresh rate of 144 Hz, which in itself suggests that this television is something more than a regular "60 Hz" panel. What's more – if we connect the C7K to a computer and set the resolution to Full HD. But we will write more about this in the section for gamers and cooperation with PCs. Returning to everyday use – both sports and films look very good here. Thanks to the fast panel and well-functioning motion smoother, the C7K is great for watching matches, as well as for film screenings. In the menu, we find two sliders – blur reduction and flicker reduction – which allow you to adjust the smoothness effect to your own preferences. At lower settings, we get a more cinematic effect, with a slight choppy motion. At higher settings – the image becomes more theatrical, overly smooth. Everyone can set it to their liking.

Samsung again used a panel with a maximum refresh rate of 144 Hz. Refresh rates up to 120 Hz primarily offer greater possibilities with material that contains a lot of motion. The TV can use additional motion-smoothing systems that can improve fluidity 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 fairly slow response time, and consequently fairly pronounced motion blur. With rapidly moving objects, especially on a dark background, trails are easy to notice. There is also a slight doubling of edges, which can be visible even when additional motion-enhancement systems are switched off. We saw similar behaviour in last year's The Frame 2025, and it's a shame Samsung hasn't addressed this issue. The 144 Hz itself provides a good foundation, but the panel's response time still limits this TV.

The TCL C7K is a television that on paper appears to be the dream equipment for gamers – and most importantly, it also holds up in practice. To start with the good news: there are two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, making full use of their capabilities. The panel itself supports a refresh rate of 144 Hz, which provides a significant advantage in fast-paced games. Additionally, it comes with a complete set of gaming features: VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and support for Dolby Vision in games. There is also an HGiG mode that allows for an HDR effect in line with the creators' intentions. GameBar, which is an information bar for gamers. It works quickly, looks clear (like a Nintendo console👌), and shows the most important information: the current frame rate, VRR status, and even HDR parameters.

In terms of gaming features, The Frame is practically on a par with Samsung’s top televisions. When a console is connected the TV automatically switches to Game Mode thanks to ALLM, so we do not have to change settings manually each time. There is also VRR, which matches the screen refresh rate to the number of frames produced by the console or PC. This helps avoid the characteristic screen tearing when frame rates drop. The Frame of course supports 4K at 120 Hz, so you can take advantage of the capabilities of the PlayStation 5 or Xbox Series X in games that offer higher frame rates. HGiG also works correctly. With HDR properly configured on the console, the TV does not try to brighten the picture further on its own, so bright effects in games are displayed as they should be. Samsung also includes a Game Bar. It is a handy menu you can bring up without leaving the game. There you can check VRR operation and the current frame rate, and quickly change the most important gaming-related settings. With a PC the possibilities are even greater, because the aforementioned Full HD mode lets you increase the refresh rate up to 240 Hz. There is essentially one feature missing that Samsung has already got us used to, namely Dolby Vision Gaming. Xbox owners will notice this most, as that console can use Dolby Vision in games. There is one more thing worth mentioning specific to this model. Its One Connect module has only one HDMI 2.1 port, so you must plug the console or PC into that port if you want to use 4K at 120 Hz. Fortunately Samsung did not combine this port with eARC. The soundbar can therefore be connected separately (3) and you still have a full HDMI 2.1 available for the console.
