Hisense U6NQ vs TCL C7K / QM7K 55"-85"

Hisense U6NQ offers a stable HDR effect, which is a rarity in TVs with local dimming. On most streaming platforms, in films and series recorded in 4K, the television delivers consistent performance – in every tested scene, regardless of difficulty, the brightness is around 450 nits. This is a pleasant surprise, as in many models of this class, there are notable differences – some scenes are well-lit, while others are heavily dimmed by dimming algorithms. However, the Hisense U6NQ prioritises maintaining higher brightness, which comes at the expense of black levels, as mentioned in the contrast test paragraph.

The HDR effect on the U6NQ is satisfactory, offering a noticeable "burst" of light in bright moments, although it is worth noting the previously mentioned blooming, which may be visible in more challenging scenes. In terms of colours, the television also performs decently – the coverage of the DCI-P3 palette is 89%, and BT.2020 is 71%. Although these are not results that would impress more demanding users, for beginners in the world of high-quality materials, the U6NQ serves as a solid choice. Therefore, it presents an interesting proposition as an "entry-level" television for home cinema.

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.

Hisense U6NQ in Filmmaker mode offers really decent colour reproduction, although it's worth noting that differences between individual units can be noticeable. The model we tested was pleasantly surprising, especially with HD content in SDR quality. The white balance was correct here, and errors around 3–4 ΔE should be acceptable for the average viewer. The television performed slightly worse with colour reproduction in 4K HDR materials. The dominance of blue shades led to unnatural cool tones on the Colour Checker chart, giving the image a "store-bought" character. Combined with issues in brightness characteristics – gamma and EOTF curve caused some parts of the image to be too dark – the Filmmaker mode loses some of its credibility in this case. Although the factory settings of the tested unit deserve praise, especially in SDR, there were still minor shortcomings that would require correction to fully exploit the capabilities of the television.

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 factory settings of the Filmmaker mode on the Hisense U6NQ were quite good, we decided to carry out a calibration to fully assess the capabilities of this model. Only after such an adjustment can one see how the television performs under ideal conditions. In the case of SDR content, which was already at a high level, we managed to further improve the white balance. However, the most significant change came from correcting the brightness characteristics – the gamma was optimised and no longer causes excessive dimming of the image, which improves its naturalness.

For 4K HDR content, the calibration also produced positive effects. We eliminated the blue dominance issue, resulting in a more balanced and natural image. However, managing brightness in HDR materials remains a more complex matter. The EOTF curve, while having problems with dimming the image in the 10–30% brightness range in laboratory conditions, reveals other shortcomings in real scenes. The television tends to excessively brighten the smallest elements on the screen. As a result, this leads to visible halo effects around bright objects. This phenomenon, which we mentioned earlier in the context of contrast and HDR, arises from the technological limitations of the particular model and is often difficult to eliminate.

In short: although the Filmmaker mode with factory settings performed decently, calibration allowed us to extract an even better effect – minor adjustments resulted in a more balanced image, especially in HDR content. For users seeking the highest quality picture, calibration will be a beneficial step.

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.

With high-quality materials, such as 4K, tonal transitions on U6NQ look really good – the colours blend nicely, and the image is coherent. Unfortunately, when we move to content in lower resolutions, the television does not offer any additional features that could improve this aspect. An example is the test with the light bulb, where it is clearly visible that the television has a problem with rendering subtle tonal transitions.

However, digital processing performs quite well. The image looks pliable, is pleasantly soft, and free from excessive banding. Moreover, thanks to the sharpness settings, it can be adjusted according to personal preferences – whether towards a softer or sharper image. Overall, although scaling lower quality materials could be better, the television handles image processing effectively.

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.

Hisense U6NQ offers native 60 Hz refresh rate at 4K resolution, but the manufacturer has added a feature that allows the refresh rate to be increased to 120 Hz, at the cost of reducing the resolution to Full HD. This solution, which we have seen before in TCL televisions, such as the C655 or C655 PRO. This gives the user the choice – higher motion fluidity or full resolution. This is a sensible approach, especially considering that many games on next-generation consoles do not achieve full performance in 4K at 120 Hz.

As for movies, the television is equipped with a motion smoothing feature that allows you to adjust the motion characteristics to your own preferences. This allows for a more cinematic effect or increased fluidity in dynamic scenes. Overall, Hisense U6NQ offers reasonable solutions in terms of motion fluidity that should satisfy both gamers and movie enthusiasts.

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.

Hisense U6NQ offers the option to choose between 4K at 60 Hz and Full HD with a refresh rate of 120 Hz. This solution may appeal to gamers who want to decide what is more important to them – higher resolution or smoothness. The television supports features such as ALLM and VRR, which help in achieving smoother gameplay. A nice addition is the GameBar – an easy-to-use panel that allows you to quickly change picture settings and check statistics. There is also a Dolby Vision Game mode, which operates with low input lag, which is a big plus for console enthusiasts. Unfortunately, it lacks HGiG, which could further enhance HDR quality in games. Nevertheless, the Hisense U6NQ performs quite well as a gaming television, especially for those who play occasionally and do not require the highest refresh rates in 4K. It is a solid choice for less demanding users.

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.
