TCL C7K / QM7K vs Samsung Q8F

TCL C7K is one of the brightest MiniLED TVs in its price class. Under optimal testing conditions, the screen can achieve over 1200 nits, resulting in impressive, at times dazzlingly bright scenes. And most importantly – this isn’t just a theory from measurements. In practice, even the brightest moments in movies can shine with true cinematic grandeur. Home HDR cinema fans should be really pleased.

The impression is fantastic, especially in scenes with large areas of brightness – a white sky, explosions, sun reflections, or magical sunsets can surprise with an intensity of light that rarely appears in this price range.

However, things get a bit worse when more challenging scenarios appear on the screen, previously described in terms of contrast – that is, images full of details, with small bright elements on a dark background. In such cases, the C7K often opts to preserve black at the expense of brightness. An example? Scenes from movies like Sicario 2 or Life of Pi, where small light sources (like a distant lantern) may become less visible, and details in the lights are simply dimmed or blend into the background.

For many viewers, this may be an acceptable compromise – as we achieve deep blacks and pleasant image depth. Nevertheless, it’s important to recognise that the visibility of small details in bright areas is not this model's strong suit. It’s simply a technological limitation that still exists – even with over 300 zones.

In terms of brightness, the Samsung Q8F performs surprisingly well for a TV without local dimming. It measures up to 500 nits, which in practice means that most movie and series scenes look pleasant, and it cannot be faulted for lacking the "HDR effect." In films like Life of Pi or The Meg, the screen can burst with bright light, delivering a level of lighting effect that is satisfying. It struggles more in challenging moments—such as dark scenes with single bright points. The global dimming used causes the TV to darken the image to maintain deep blacks, but at the expense of detail brightness. This is clearly visible in the scene from Sicario 2, where the brightness of the helicopter lights dropped to around 200 nits. This is a deliberate design choice that gives the impression of deeper blacks but takes some shine away from individual elements, and one should simply keep that in mind. Regarding colour reproduction, the Q8F uses quantum dot technology, which expands the colour gamut. A coverage of the DCI-P3 palette at 91% can be considered a decent result, although it is not a record-breaking figure compared to other QLEDs.

A new feature in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now has been found in most competing brands. This is great news, as this mode is considered the most faithful to the original vision of the creators and is often recommended by enthusiasts of quality visuals. 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 faults. There are issues with inaccurate white balance, particularly a slight blue tint that resulted in cool, somewhat greyish skin tones. But that wasn’t the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible on gamma and EOTF charts. The image was simply too bright, at times even blown out, which affected not only the texture of scenes but also the overall viewing experience. Some details were just lost, and the entire image looked as if someone had overdone the brightness slider. As always, we decided to see what could be squeezed out of it after calibration. And this is where things started to get really interesting…

We decided to check out the Filmmaker mode because right out of the box it gave us the best picture. However, that doesn't mean it was perfect. The white balance had too much of a blue and red tint, causing the whites to lean towards a slight purple-pink hue. Such imbalance affected the visibility of virtually all colours, which is clearly seen in the comparison photo below. The brightness characteristics in SDR content were quite well calibrated, although in HDR materials we noticed that the TV didn't always handle its global dimming well — at times the screen was too dim, while at other times it could suddenly brighten up. Fortunately, issues related to colours can be effectively corrected with calibration tools, so we decided to get to work.

After calibration, the TCL C7K showed 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, which means that the image is very close to what the creators intended. Unfortunately, it was a different story with 4K HDR content. While we were able to slightly calm down the white balance and correct its earlier errors, it was still evident that the TV has some "MiniLED traits", particularly in brightness management. When we checked how the C7K handled the EOTF curve on real film scenes, rather than just on synthetic test patterns, it turned out that the screen still had a tendency to slightly brighten the entire image. This affects the overall experience – the black loses some depth, and the image becomes less contrasty than it should be. Despite these minor issues with 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 colour tuning, natural skin tones, and pleasant brightness make movie watching and everyday content viewing more than satisfactory.

After calibration, we managed to correct the white balance to almost perfection. Older SDR content looks fantastic — most errors are within a value of 2, which is definitely below the threshold of human perceptibility. In HDR, we also brought the white balance to an acceptable level, but a different problem arises here. So why are there still relatively large errors in colour reproduction? This is mainly due to the limited colour palette and the way the television manages brightness. The global dimming technique used does not give the user control in the settings, so analysing the EOTF curve in HDR films, it's clear that the Q8F can modify luminance on its own. This can be seen as a limitation, but still, the image after calibration is much more enjoyable to watch than in the factory version.

TCL C7K has a feature that, according to the manufacturer, is meant to smooth out undesirable colour transitions – something like a 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. Worse still – the feature 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 even so – it's better to simply turn this option off.

When it comes to upscaling lower resolution content, it's already better. SD and HD materials look quite decent, although at times we had the impression 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 wasn't artificially cropped – everything fit on the screen as it should.

Let's see how the Q8F handles older content, which often has poor quality. Starting with the positives: the upscaling works really well. The TV performs nicely with both classic television and materials from YouTube, not giving the impression that we're dealing with something completely unattractive. It struggles more with content in very low resolutions, such as 576p — the image can be cropped, and unfortunately, the overscan phenomenon cannot be disabled. Moreover, the digital processing does not look great either. The noise reduction feature, instead of removing unwanted artefacts, smooths out almost everything: film grain (which many viewers desire) disappears along with the texture of the image, and actors' faces start to resemble characters from cheap Turkish soap operas. It's hard to consider this option useful — it's best left completely off. Perhaps Samsung will refine the function’s performance in updates, but for now, it’s difficult to view it as anything other than an unnecessary addition.

TCL C7K handles motion fluidity really well. The panel it uses offers a refresh rate of 144 Hz, which suggests that this TV is more than just a standard "60 Hz" panel. Furthermore, if we connect the C7K to a computer and set the resolution to Full HD. But we will write more about this in the paragraph on gamers and PC compatibility. Returning to everyday use – both sports and movies look very good here. Thanks to the fast panel and the well-functioning motion smoother, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – motion blur reduction and flicker reduction – that allow you to adjust the fluidity effect to your own preferences. At lower settings, we get a more cinematic effect, with slight judder. At higher settings – the image becomes more theatrical, fluid to the point of excess. Whatever your preference – everyone can set it their own way.

Due to the applied 60 Hz panel, it's hard to call the Q8F a television made for gaming or watching sports. The panel isn't particularly fast, making motion blur clearly visible. If you were expecting a spectacular, almost 'stadium-like' experience during broadcasts, you might feel a bit disappointed. Fortunately, for movies and series, Samsung hasn't given up on the motion smoothing function. It's nothing more than a smoother that allows for improved fluidity of productions recorded at 24 or 30 frames per second. This way, you can decide for yourself whether you prefer a more fluid, 'television-like' image or to retain the cinematic character. It all depends on the viewer's preferences, and the ability to adjust this parameter is undoubtedly a plus.

TCL C7K is a television that on paper looks like the perfect equipment for gamers – and most importantly, it performs well in practice too. Here's some good news: we have two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, using all 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 set 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 that align with the creators' intentions. GameBar, which is an information bar for gamers. It operates quickly, looks clear (like a Nintendo console👌), and shows what's most important: the current frame rate, VRR status, and even HDR parameters.

It's not entirely clear what Samsung has messed up this year with its TVs, but the Q8F isn't free from all the confusion with updates and shortcomings. While its older cousin, the Q67D, could still be recommended with a clear conscience to casual gamers, it's hard to find a reason to do so here. Aside from the automatic game mode and the attractively designed Game Bar, we get practically nothing that could appeal to gamers. The lack of proper HGiG implementation is a major issue, especially since the feature simply disappeared after the 1126 update. The situation with VRR is even worse. Even though it appears in the manufacturer's brochures and shows up in the Game Bar, we couldn't get it to work. The Xbox Series X console wouldn't allow it to be activated at all, and the option remained greyed out and inactive. It's difficult to praise such a TV even to casual gamers, which is a shame because Samsung has had a strong selling point in the gaming segment for years.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.
