Samsung U8000F (VA) vs TCL C7K / QM7K

While the U8000F with its VA panel can still be praised for decent blacks, there are no such accolades when it comes to brightness—particularly in HDR scenes. The television only achieves a maximum of just under 250 nits, which is simply too low to talk about any impressive light effects. Bright elements appear washed out, and scenes that should shine look rather flat. An interesting situation occurred during our testing of a scene from the movie Sicario 2— the screen noticeably darkened, as if the television was trying to hide its limitations in displaying blacks. One might get the impression that the device artificially darkens the image to improve contrast, but in practice, the effect doesn't make much difference, apart from the fact that we see less on the screen. Additionally, there’s the issue of colours—the U8000F doesn’t support a wide colour gamut, so one shouldn’t expect vibrant, saturated hues known from better models. The HDR image here resembles a slightly brightened SDR and... maybe that’s not such a bad thing. For this model, it’s not worth expecting a cinematic experience—better to treat HDR as a modest addition.

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.

Samsung U8000F has been tested by us in the best picture mode it offers out of the box – that is, Filmmaker Mode. This profile is supposed to theoretically provide a neutral, cinematic image, free of unnecessary enhancements and artificial beautifications. In the case of SDR content – mainly in HD or SD resolution – the television already presented itself surprisingly reasonably right out of the box. The only noticeable imperfection was brightness management. The gamma chart showed some deviations – slight brightening or dimming of certain tones – but in practice, this did not significantly affect the viewing experience. For a television in this segment, it performs quite well.

However, the situation in HDR mode looks significantly weaker. Although white balance was still acceptable, colour errors were very evident. In the Color Checker test, almost every sample was outside the target point, and the image itself appeared unnatural – colours were skewed, sometimes too cool, and at other times simply dull and lifeless. The main issue lies in hardware limitations – the U8000F does not support the wide colour gamut of DCI-P3, so it is physically unable to reproduce the colours that the HDR standard intends. Unfortunately, this is evident in almost every more demanding scene.

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…

Right out of the box, the U8000F offered a pretty decent picture in SDR for its price range. We managed to tweak it a bit further – we reduced a slight purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the TV still has a tendency to overly brighten the brightest details – the gamma chart shows a clear break that cannot be fully corrected.

On the other hand, in HDR mode, it’s noticeably weaker. It's hard to talk about any significant improvement – despite attempts to fine-tune the settings, the picture still presents considerable colour errors. A Delta E exceeding 7 indicates noticeable deviations that we couldn’t effectively reduce. Unfortunately, this is a limitation of the construction itself – the U8000F simply wasn't designed for serious HDR. In daily SDR viewing, it performs quite well, but for HDR content... it’s best not to have overly high expectations.

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.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup. This year’s model is equipped with a feature that improves the smoothness of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but still – it can be confidently said that it works effectively. However, not everything has gone perfectly. The U8000F has noticeable issues with slight image stuttering when watching very old content in very low resolution. If someone plans to play their old VHS tape, they must be prepared for the image to look slightly “choppy”.

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.

The Samsung U8000F comes with a 60 Hz panel, so right from the start, it's clear that you can't expect miracles. It's simply the standard in this class – sufficient for everyday viewing, but without any fireworks. The TV offers one motion smoothing slider – a function called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in films. Higher settings provide a more "theatrical" and smoothed effect, while lower settings maintain the original character of the film with a slight 24p effect. Interestingly, there is the "LED Clear Motion" feature, or BFI mode – which inserts black frames between the frames of the image to improve motion sharpness. However, in practice, the screen flickers significantly when this is activated, and it's best to treat this as more of an experiment rather than something that genuinely improves the gaming experience.

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.

[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.

Samsung U8000F offers a basic set of features for gamers, which can still prove sufficient for less demanding users. Here we have an automatic gaming mode – when a game is launched on the console, the TV switches to low-latency mode by itself, significantly improving response time. We also find the VRR feature, or variable refresh rate, which operates in the range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the 'tearing' effect on the screen – as long as we stay within this range.

Unfortunately, that's about it when it comes to advantages. Add-ons like Game Bar or higher refresh rates are reserved for higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG feature, which should adjust the HDR image to the intentions of game developers. Unfortunately – despite this feature appearing in advertising brochures and store materials – its setup on the Xbox console turned out, in practice, to be... impossible.

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.
