TCL C7K / QM7K 55"-85" vs Samsung QN80H

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.

Samsung QN80H is without a doubt a bright TV. In synthetic tests it breaks the 1000-nit barrier, which on paper already promises a solid HDR effect. In practice the screen really shows its claws, though it can't fully spread its wings (or its backlight 🤔) in every situation. The best impression comes from bright, expansive shots. Sunlit exteriors or heavily lit scenes look really good on it. Brightness then stays around 700 nits, which gives a noticeable step up in quality over standard SDR. Problems start in dark scenes with small, pinpoint highlights. The QN80H tends to heavily dim them, doing everything it can to protect black levels. On one hand we gain better contrast, on the other... we lose some of the dynamics and the sparkle of fine HDR details. The TV therefore has considerable potential, but the dimming algorithm can be too restrictive.

Color gamut coverage

Colors are good too. The QN80H uses quantum dot technology, and in our measurements it covered 93% of the DCI-P3 space and about 70% of BT.2020. Today those results won't exactly blow anyone away, but in real-world use they're more than enough to deliver vivid, natural-looking images in most movies and TV series. Colors are properly saturated and, after proper tuning, don't look artificial or overly aggressive.

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…

The QN80H's factory settings were really good, especially compared with most TVs that come into our tests. Of course, we performed measurements in Filmmaker Mode, and that's the mode we recommend turning on right after the initial setup. In SDR material our unit was set up surprisingly well. The white balance was very even, colors looked natural, and the errors were so small they were hard to spot without measurement equipment. The only weak point was the gamma. In brighter parts of the image the TV brightened them a bit too much, so the picture sometimes lost a little depth. Even so, we'd like most TVs to look this good straight out of the box.

It was a bit worse in HDR. The white balance itself was still set correctly, so the problem wasn't with the colors but with how the QN80H managed image brightness. You could see that immediately on the EOTF chart. The TV brightened large parts of scenes too much, causing the brightest elements to blow out. Interestingly, at the same time very small points were often dimmed too much. As a result some fine detail simply disappeared. So the factory Filmmaker Mode in HDR isn't bad, but it's definitely not as well calibrated as in SDR.

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.

The biggest difference after calibration was in HDR Filmmaker mode. SDR was already very good out of the box, so we didn't have much work to do there. In HDR, however, we managed to tame the way the QN80H handled brightness, as it had been over-brightening most scenes. After calibration the picture is calmer, more natural, and much closer to how a faithful picture should look.

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.

Digital image processing in the Samsung QN80H is handled by the second-generation NQ4 AI processor. It's a chip we already know from earlier models and it still performs very well, especially with lower-resolution material. The image is effectively upscaled to 4K, but without excessive sharpening and without the feeling that the TV is forcing improvements on the source material.

The "Noise Reduction" feature also proves useful. It can noticeably reduce posterization and visible banding in poorer-quality material, particularly in low-bitrate streaming. However, it's important to remember that it doesn't work without side effects. It can remove some film grain and slightly smooth the image. So with a good-quality source we'd leave this feature off. If, however, banding and uneven tonal transitions bother you more than losing some grain, "Noise Reduction" can be a really useful addition.

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.

Motion blur and motion handling on the QN80H are really good, mainly thanks to the fast panel. In 4K the screen refreshes at up to 144 Hz, and when switched to Full HD and connected to a PC it can reach as high as 240 Hz. That's new for Samsung TVs and a nice bonus for people who want to use the TV for PC gaming as well. We were more interested, however, in how the QN80H performs at 120 Hz, since consoles use that refresh rate. Here it's really good. The panel doesn't have a big problem with the smearing typical of VA panels, and slight trails behind moving objects are mostly visible on dark backgrounds. This is nothing that would interfere with normal sports viewing or gaming. The TV also includes a motion smoothing system that Samsung calls "Image Clarity." You can adjust judder reduction and blur reduction separately, so it's easy to tailor its operation to movies, sports, or your own preferences.

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.

Samsung QN80H is a TV that scores very well on gamer-oriented features. The biggest new addition for 2026 is DLG mode, which allows refresh rates up to 240 Hz when the image is switched to Full HD resolution. This option is aimed mainly at PC users, but it also shows that Samsung is still heavily developing the gaming side of its TVs. That’s not the end of the list of advantages. The QN80H has four full-featured HDMI 2.1 ports, which in this price range still isn’t standard. You can therefore connect multiple consoles, a PC, or a soundbar at the same time without worrying which input supports the full picture capabilities. The TV also supports VRR, ALLM, and HGiG, so it’s hard to fault its basic feature set. One downside remains the lack of Dolby Vision, which may matter especially to Xbox Series X owners. That said, it’s not a flaw that rules out the QN80H as a gaming TV. Samsung includes a feature still missing from most manufacturers: its proprietary motion interpolator, Game Motion Plus. It’s a motion interpolator that also works in game mode, allowing you to improve the smoothness of titles running at 30 or 60 frames per second without a drastic increase in input lag. In practice, Game Motion Plus can make a much bigger difference than Dolby’s processing, especially in more demanding games that don’t offer a 60 FPS mode. The image becomes noticeably smoother while controls remain responsive enough. So despite the lack of Dolby Vision, the QN80H is still one of the best-equipped TVs for gamers in its class.
