Samsung U8000F (IPS) vs TCL C7K / QM7K 55"-85"

Better does not mean good – and that perfectly summarizes the capabilities of the U8092F when it comes to displaying bright movie scenes in HDR mode. The brightness of the panel is just under 250 nits, which is definitely too little to enjoy any lighting effects. An interesting situation was noted during the measurement of the fourth scene from the movie Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which are still weak). One could even suggest that the device uses some form of "global dimming," but unfortunately, the results are still very poor. To make matters worse, the television does not support a wide color gamut – the coverage of the DCI-P3 space is about 80%, so there’s no hope for truly vibrant colors. HDR images here look rather like lightly brightened SDR, and that's the form we would suggest sticking to when it comes to this television.

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 Samsung U8000F was tested in the best possible picture mode built into the TV, which is Filmmaker Mode. This mode should – at least in theory – offer a cinematic, reference-quality image without unnecessary enhancements. For SDR content (mainly HD/SD), the TV performed surprisingly well straight out of the box. White balance errors hovered around a value of 3, which is roughly at the threshold of perception. The only complaint could be about brightness management – the gamma chart showed a slight tendency to brighten or darken certain areas, but overall it performed quite well for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance wasn't terrible, the TV had significant color errors – particularly noticeable on the Color Checker chart, where almost every sample landed outside the target point. The HDR image simply looks unnatural, and colors can be shifted, dull, or too cool. This largely stems from the fact that the U8000F does not support a wide color gamut (DCI-P3). The TV is physically incapable of displaying accurate colors in HDR standard – and this unfortunately shows in every more demanding material.

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…

Although the U8000F offered quite a decent picture in SDR right out of the box, we were able to adjust it a little more. We managed to eliminate a slightly purplish tint and calibrate the gamma to a more reasonable level. However, the television still tends to overemphasize the smallest and brightest parts of the image – the gamma chart shows a characteristic "dip" that is difficult to completely correct.

Unfortunately, the situation looks worse in HDR. It's hard to talk about any significant improvement here – the television is simply not designed for HDR content. We tried to adjust the picture in the advanced settings, but despite everything, the color errors remained quite large – a delta E above 7 indicates noticeable deviations. It's a bit of a shame, but that's the charm of a budget design. In SDR, the U8000F performs just fine, while HDR is simply not its league.

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.

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 function to improve the fluidity 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 even so – it can be confidently said that it works effectively.

However, not everything went perfectly. The U8000F has noticeable issues with slight frame cutting when watching very old content in very low resolution. If someone plans to play their old VHS tape, they should be prepared for the image to appear slightly “cut off.”

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.

The Samsung U8000F is equipped with a 60 Hz panel, so right from the start, it’s clear that we shouldn’t expect any miracles. This is simply the standard in this class – sufficient for everyday viewing, but without any fireworks.

The TV offers one motion smoothing slider – a feature called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in movies. Higher settings provide a more "theatrical" and smoothed effect, while lower settings help retain the original character of the film with a slight 24p effect. Interestingly, there is a feature called "Clear Motion LED", which is a BFI mode – that inserts black frames between the frames of the picture to improve motion clarity. However, in practice, the screen flickers significantly when activated, and it should be regarded more as an experiment than something that realistically enhances gaming comfort.

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 U8000F offers a basic set of features for gamers, which nonetheless may be sufficient for less demanding users. We have an automatic game mode here – when a game is launched on the console, the TV automatically switches to low latency mode, which significantly improves response time. We also find the VRR feature, or variable refresh rate, which operates within a range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the "tearing" effect, as long as we stay within this range.

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

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.
