Hisense U8Q vs TCL C7K / QM7K 55"-85"

When it comes to HDR, the Hisense U8Q shows its claws. On paper, meaning in synthetic measurement tests, the TV can "push out" nearly 4000 nits of peak brightness. This is a value that most models can only envy. In practice, this translates to very strong light effects in movies – in some scenes we managed to measure real levels from 1500 to 2000 nits, which is a level usually reserved for the absolute top-tier TVs on the market.

Of course, it's not always so perfect. In small, point-like elements, brightness can drop – a good example is scene number 4 from the movie Sicario 2, where instead of thousands of nits we get about 500. But it's worth noting that the effect doesn't disappear completely – the light is still visible, and the image doesn't appear artificially dimmed. This is a typical issue with Mini LEDs, so it’s hard to consider it a major drawback.

However, a huge plus has to be granted for colour reproduction. Thanks to additional coatings improving colour saturation, the U8Q almost covers the entire DCI-P3 colour space (98%), and for the wider BT.2020 gamut it achieved over 80%. This is an excellent result that makes HDR films look juicy, intense, and just very cinematic.

In terms of brightness, the models ranging from 55 to 85 inches in the C7K series are truly impressive. Under optimal testing conditions, the 65-inch screen exceeded 1200 nits, which in practice means that the brightest scenes can dazzle with almost cinematic brilliance. These are not just dry figures from measurements – during screenings, bright skies, explosions, or reflections of light on water looked incredibly striking, often giving the impression that the television exceeds its price range. This is particularly effective in scenes with large areas of illumination, where the screen fills with intense brightness – for instance, in sun-drenched shots or during dynamic action sequences. Viewers looking for strong HDR will definitely be satisfied.

However, scenes that require precise backlight control – with tiny points of light against a dark background – prove to be 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 lighthouse or single reflections, may appear 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 not offered by standard LCDs, but this comes at the cost of limited visibility of the tiniest lights.

We have to admit that when the U8Q arrived in our editorial office, we were slightly surprised… and in a good way. Usually, white balance in televisions immediately requires adjustment – it can be too warm or too cold, which immediately causes strange colour errors. Meanwhile, here the situation looks really good straight out of the box. Of course, we’re talking about our unit, so there’s no guarantee that every model will be tuned as well, but in our case, the first impressions were very positive. The only more noticeable issue was related to how the television manages brightness. Looking at the EOTF chart, it’s clear that the U8Q tends to brighten small elements on the screen. This, in turn, caused what we mentioned earlier – slight overexposure and the impression that the whole scene is a bit too bright. However, this is not a flaw that negates the picture, rather an effect characteristic of this model.

The new feature in TCL TVs 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 regarded as the one that best 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 could critique the incorrect white balance, particularly the slight dominance of blue, which caused cool, slightly greyish skin tones. But that was not the biggest issue. The main complaint was the excessive brightness exposure, which is clearly visible on the gamma and EOTF graphs. The picture was simply too bright, at times even blown out, which affected not only the richness of the scenes but also the overall viewing experience. Some details were simply lost, and the whole image looked as if someone had overdone the brightness slider a bit. As always – we decided to see what could be squeezed out of this after calibration. And that’s where it started to get really interesting…

Of course, we wouldn’t be ourselves if we didn’t make adjustments to the white balance. After calibration, we managed to level the SDR signal to near perfection – older films, YouTube content, and classic television looked nearly ideal on the U8Q. It’s truly an impressive level that shows this model can do a lot if given a bit of help. Unfortunately, the situation is different with HDR content. The colours themselves don’t pose much of a problem, but the biggest issue with the U8Q remains the EOTF brightness characteristics. In practice, the television tends to "shoot" above how the image should originally look. It’s this slight "blowout" we noticed earlier in comparisons with the best screens on the market. It’s a bit of a shame that this characteristic can't be completely tamed – if we could maintain equally good brightness control in HDR as we do in SDR, we would be looking at an absolutely reference-level image.

After calibration, the TCL C7K put on a really good show, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics, resulting in colour errors on the ColorChecker palette dropping below a value of 2. For the uninitiated – this is an almost perfect score, meaning the image is very close to what the creators intended. Unfortunately, things didn’t look as good with 4K HDR content. While we managed to slightly calm down the white balance and correct its previous errors, it still shows that the TV has some "MiniLED traits," especially in brightness management. When we checked how the C7K handles the EOTF curve on actual movie scenes, rather than just synthetic test patterns, it turned out that the screen still has a tendency to slightly brighten the entire image. This affects the overall experience – blacks lose 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 really very good. After calibration, the C7K can display an image that can successfully compete with much more expensive models. Good tuning of colours, natural skin tones, and pleasant brightness make movie sessions and everyday content viewing more than satisfying.

Hisense U8Q handles lower quality materials quite well. The television can smooth tonal transitions thanks to the “Smooth and Gradient Picture” feature – it works best on the Medium setting. It nicely dims unwanted bands and irregularities in the image, but importantly, it doesn't remove the film grain or fine details.

The upscaling itself is also at a good level. Image from lower resolutions appears smooth and soft, sometimes a bit too much – we get a plastic effect that may not appeal to everyone. Fortunately, this can be easily corrected with the sharpness slider, allowing you to adjust the image to your personal preferences.

TCL C7K comes with a feature that, according to the manufacturer, aims to smooth out unwanted colour 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. And worse still – the feature can cut out elements from the image that should remain. Fortunately, film grain is left untouched, so at least it doesn't smooth everything indiscriminately, but even so – it's best to just 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 felt that the image loses sharpness and becomes too soft – as if something had taken 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.

Hisense U8Q has a panel that can refresh the image up to 165 Hz in 4K resolution. In practice, this will mainly benefit PC gamers, but as they say – better to have it than not 😊. For movies and series, we have a built-in smoother called Ultra Motion Smoothing. In the settings, it can be easily adjusted to your own preferences – whether you want a more ‘cinematic’ frame rate or a smooth, theatrical spectacle.

TCL C7K handles motion smoothness really well. The panel used in it offers a refresh rate of 144 Hz, which alone suggests that this TV is more than just a regular "60 Hz" panel. Moreover, 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 PC compatibility. Returning to everyday use – both sports and movies look very good here. Thanks to the quick panel and the well-functioning motion smoothening feature, the C7K is great for watching matches as well as for movie screenings. In the menu, we find two sliders – blur reduction and flicker reduction – that allow adjusting the smoothness effect to personal preferences. At lower settings, we get a more cinematic effect, with a slight judder. At higher settings – the image becomes more theatrical, smoothly even to excess. Whatever your taste, everyone can set it to their liking.

In terms of features, the Hisense U8Q has practically everything one would expect from a modern gaming television. Thanks to the new processor, the manufacturer has managed to implement three HDMI 2.1 ports, so there’s no trouble connecting multiple consoles or a computer. On top of that, it includes all the key technologies – Game Bar with parameter previews, variable refresh rate (VRR), automatic game mode (ALLM)… in a word, a complete set.

But as often happens with Hisense, it’s missing just a bit from perfection. The biggest drawback remains the lack of support for the HGiG format, which allows the TV's brightness to be adjusted to the console and gets the most out of HDR in games. It’s a shame because if this feature were included, we’d have a device practically made for gamers. As it stands, the U8Q remains “only” a very good choice 😉

TCL C7K is a TV that on paper looks like the dream gear for a gamer – and most importantly, it also holds up in practice. First, the good news: we have two HDMI 2.1 ports with full bandwidth, so we can easily connect both a console and a computer, making use of all their capabilities. The panel itself supports a refresh rate of 144 Hz, which gives a considerable advantage in fast-paced games. On top of that, it comes with a full suite of gaming features: VRR (variable refresh rate), ALLM (automatic low latency mode), and Dolby Vision support in games. There’s also an HGiG mode that provides an HDR effect aligned with the creators' intentions. GameBar, which is an information bar for gamers. It operates quickly, looks clear (like a Nintendo console👌), and displays what matters most: the current frame rate, VRR status, and even HDR parameters.
