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

Better does not mean good – and that is exactly how to summarise the capabilities of 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 light effects. An interesting situation was observed during the measurement of the fourth scene from the film Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which remain weak anyway). One might even suggest that the device is using some form of 'global dimming', but unfortunately – the results are still very poor. To make matters worse, the television does not support a wide colour gamut – the coverage of the DCI-P3 space is around 80%, so one cannot expect truly vibrant colours. The HDR image here looks more like a slightly brightened SDR, and it is this form that we would suggest sticking to when it comes to this television.

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 Samsung U8000F has been tested in the best possible picture mode built into the television, namely Filmmaker Mode. This mode should – at least in theory – offer a cinematic, reference picture without unnecessary enhancements. In the case of SDR content (mainly HD/SD), the television, out of the box, showed itself surprisingly well. Errors in white balance hovered around a value of 3, which is roughly on the edge of perceptibility. The only complaint could be about brightness management – the gamma graph showed a slight tendency to lighten or darken certain sections, but even so, the overall performance is quite good for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance was not terrible, the television had significant colour errors – particularly evident in the Color Checker graph, where almost every sample hit outside the target point. The picture in HDR simply looks unnatural, and the colours can be shifted, dull, or too cool. This largely stems from the fact that the U8000F does not support a wide colour gamut (DCI-P3). The television is physically unable to display correct colours in the HDR standard – and unfortunately, this is felt in every more demanding material.

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…

Although the U8000F already offered a fairly well-balanced image in SDR straight out of the box, we were able to refine it a bit further. We managed to eliminate a slight purple tint and adjust the gamma to a more sensible level. However, the television still has a tendency to overexpose the smallest and brightest parts of the image – the gamma chart shows a characteristic 'dip' that is difficult to completely straighten out.

Unfortunately, the situation is worse in HDR. It's hard to speak of any significant improvement here – the television is simply not designed for HDR content. We tried to correct the image in the advanced settings, but despite our efforts, the colour errors remained substantial – a delta E above 7 indicates very noticeable deviations. It's a bit disappointing, but that's the nature of budget construction. In SDR, the U8000F performs reasonably well, whereas HDR is just not its league.

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.

When it comes to how the Samsung U8000F handles lower quality materials, we must admit that Samsung has made progress compared to its predecessor from last year – namely the DU7192 model, which theoretically occupies the same spot in the range.

This year's model has been equipped with a feature that enhances the fluidity of tonal transitions, which has been implemented much better than last year. Yes, the television still uses fairly strong algorithms that can distort details or remove film grain, but despite that – 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 reckon with the fact that the image may appear slightly "choppy".

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.

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

The television offers a single 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. An interesting feature is “LED Clear Motion”, which is a BFI mode – that inserts black frames between frames of the image to improve motion clarity. However, in practice, the screen flickers quite a bit when this feature is activated, and it should be regarded more as an experiment than something that genuinely enhances the comfort of gaming.

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.

The Samsung U8000F offers a basic set of features for gamers, which may still prove sufficient for less demanding users. It includes an automatic game mode – upon launching a game on the console, the television automatically switches to low latency mode, significantly improving response times. We also find a VRR feature, meaning variable refresh rate, which operates within a range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the effect of screen tearing – provided, of course, we stay within this range.

Unfortunately, that is about it when it comes to advantages. Add-ons like Game Bar or higher refresh rates are reserved for higher models of Samsung's 2025 line. In theory, the television also supports the HGiG function, which should adjust HDR images to the intentions of game developers. Unfortunately – despite this feature appearing in brochures and retail materials – its configuration on the Xbox console has proven to be... impossible in practice.

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.
