Hisense U7NQ vs TCL C7K / QM7K

The Hisense U7NQ 65 television showed considerable potential on the luminance chart, exceeding the 1000 nits barrier and easily achieving very high brightness results in the first, third, and fifth test scenes. However, as before, in the second and fourth test scenes, such as from the film Sicario 2, there are significant issues with maintaining brightness, and results around 200 nits are very disappointing. Despite a large number of dimming zones, the algorithm in the television responsible for controlling these zones fails to respond adequately — in this case, it significantly dims small elements such as the moon or the light from a helicopter. The bright light that should dazzle us is too dim to be considered HDR effect. Nevertheless, it is worth praising the television for its high coverage of the DCI-P3 colour gamut at 96%, which allows it to represent most film scenes well.

TCL C7K is one of the brightest MiniLED televisions in its price range. Under the best testing conditions, the screen managed to achieve over 1200 nits, resulting in impressive, at times almost blindingly bright scenes. And most importantly – this is not just a theory based on measurements. In practice, the brightest parts of films can shine with true cinematic grandeur. Fans of home HDR cinema should be truly satisfied.

The impression is excellent, 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 is rarely seen in this price range.

However, it gets a bit worse when more challenging scenarios appear on the screen, as described when discussing contrast – that is, images full of details, with small, bright elements on a dark background. In such cases, the C7K often decides to preserve black levels at the expense of brightness. An example? Scenes from the films Sicario 2 or Life of Pi, where small light sources (like a distant lantern) can 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 black levels and a pleasing plasticity of the image. Nevertheless, it is worth being aware that the visibility of small details in bright areas is not this model's strongest suit. It is simply a technological limitation that still exists – even with over 300 zones.

The Chinese manufacturer offers various picture settings in its televisions, but the best mode in this model is undoubtedly Filmmaker Mode. Despite its name, this mode has its issues: white balance, although roughly correct, is characterised by a strong dominance of warm tones due to the oversaturation of red, both in 4K and HD content. The Colour Checker test confirms these errors — deviations of samples towards inappropriate hues are visible. As for brightness characteristics, the gamma responsible for HD content shows values below 2.4, leading to some brightening of the screen. Meanwhile, the EOTF curve reveals the television's struggles with displaying small bright elements, as confirmed by the previously described paragraphs.

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 to be the truest 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 without its flaws. There can be criticism of the incorrect white balance, particularly a slight dominance of blue, which resulted in cool, somewhat 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 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 simply lost, and the entire image looked as if someone had slightly overcooked the brightness slider. As always, we decided to check what could be extracted from this after calibration. And that’s where it started to get really interesting…

Hisense televisions offer many image correction tools that allow users to adjust settings to their own preferences, which is why we decided to take advantage of these capabilities to bring the image quality closer to a reference standard. In terms of white balance, we were able to eliminate the dominance of the red colour, resulting in more neutral hues, which allowed for a more realistic image in both 4K and HD materials. We observed similar improvements in brightness characteristics. The gamma, which previously led to excessive screen brightness, was corrected, contributing to better detail reproduction in the darker areas of the image while maintaining a natural tonal balance.

However, the biggest challenge was calibrating the EOTF curve, which corresponds to brightness in 4K materials. At first glance, the EOTF value appeared nearly perfect, but detailed tests showed somewhat different results. When we examined it more closely — especially using the filter on the right side of the EOTF chart — we noticed how the television manipulated 4K film materials, often significantly boosting brightness. This effect was particularly noticeable in scenes from films such as Pan and Billy Lynn, where the television attempted to artificially increase the brightness of elements, affecting their naturalness. Despite these imperfections, the calibration yielded positive results, especially in terms of tonal improvement. For most users, the final effect should be satisfactory, particularly if they are keen on bringing the image quality closer to professional reference standards.

After calibration, the TCL C7K showcased 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 to the point that colour errors on the ColorChecker palette dropped 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, the situation was worse with 4K HDR content. Although we managed to gently stabilize the white balance and correct its previous errors, it was still evident that the television has certain "MiniLED traits," especially in brightness management. When we checked how the C7K handled the EOTF curve on actual film scenes, rather than just on synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This impacts 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 truly very good. After calibration, the C7K can display an image that can compete successfully with much more expensive models. Good colour tuning, natural skin tones, and pleasant brightness make movie sessions and everyday viewing of content more than satisfactory.

When it comes to smoothing tonal transitions, despite the presence of the "Smooth and Gradient Image" function in the test sequence, we did not notice that the function made any difference — we recommend turning it off. As for upscaling, the television handled our model reasonably well, and the branches in the background are not overly jagged — the image appears quite plastic. However, it was slightly cropped by the so-called overscan.

TCL C7K is equipped with a feature that, according to the manufacturer, is meant to smooth out unwanted colour transitions – a sort of rescue for less successful tonal shifts. It is called "Gradual Smoothing" and… well, it sounds ambitious, but in practice it works very poorly. Regardless of whether we set it to a low or high level, the difference is minimal. Worst of all, the feature can cut out elements from the picture that should be there. Fortunately, 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 is somewhat 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 definition. Fortunately, with very low sources (e.g. 576p), there was no overscan effect, meaning the picture was not artificially cropped – everything fit on the screen as it should.

Hisense U7NQ has a refresh rate of 144 Hz, which definitely contributes to smooth movement. For film enthusiasts, two functions are available: judder reduction and motion blur reduction. The judder reduction function minimises the effect known as judder, or unpleasant jumps in the image, particularly noticeable at lower frame rates. Meanwhile, motion blur reduction helps to sharpen fast-moving objects, which is useful when watching dynamic action scenes.

As for ghosting, the television has a good response time, meaning excessive ghosting is not visible, except in specific situations, such as the test with the little green man on a dark background. In such cases, slight artefacts may appear, but overall the television handles dynamic images well, providing satisfactory motion quality.

The TCL C7K handles motion fluidity really very well. The matrix used in it offers a refresh rate of 144 Hz, which in itself suggests that this television is more than just a regular "60 Hz" panel. Furthermore – if we connect the C7K to a computer and set the resolution to Full HD. But we'll write more about this in the paragraph about gamers and PC collaboration. Returning to everyday use – both sports and films look very good here. Thanks to the fast panel and well-functioning motion smoothing, 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 – which allow us to adjust the fluidity effect to our own preferences. At lower settings, we get a more cinematic effect, with slight stuttering motion. At higher settings – the picture becomes more theatrical, fluid to the point of excess. Everyone has their own preferences – anyone can set it to their liking.

Hisense U7NQ offers everything a gamer might need for comfortable gameplay. The television supports a refresh rate of 144 Hz, providing an incredibly smooth image, especially in dynamic action games. The VRR (variable refresh rate) feature ensures that the image adapts to varying frames per second, eliminating stuttering and screen tearing. Additionally, there is an ALLM (automatic low latency mode) feature, which automatically switches the television to game mode, minimising input lag.

The television also supports Dolby Vision, which is particularly important for gamers who appreciate high contrast and rich colours in games that support this format. The Hisense U7NQ also has a Game Bar feature that allows quick access to the most important settings during gameplay, as well as support for G-Sync technology, further reducing screen tearing effects.

Unfortunately, despite a wide range of features, it lacks support for the most popular HDR format in gaming — HGiG. This may be disappointing for gamers who expect optimal detail reproduction in HDR scenes. Nevertheless, the other features make the Hisense U7NQ a solid choice for any console gaming enthusiast.

The TCL C7K is a television that on paper appears to be the dream equipment for gamers – and most importantly, it holds up in practice too. To start with good news: there are two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, taking advantage of all their capabilities. The panel itself supports a refresh rate of 144 Hz, which gives a significant advantage in dynamic games. There is also a complete set of gaming features: VRR (variable refresh rate), ALLM (automatic low-latency mode), and support for Dolby Vision in games. There is also the HGiG mode, which allows for HDR effects consistent with the creators' intentions. GameBar, an information bar for gamers. It works quickly, looks clear (like a Nintendo console👌), and shows what matters most: the current frame rate, VRR status, and even HDR parameters.
