Hisense U7NQ vs TCL C75B

The Hisense U7NQ 65 television showed impressive capabilities on the luminance chart, surpassing the 1000 nit barrier and achieving very high brightness scores effortlessly in the first, third, and fifth test scenes. However, just like 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 the large number of dimming zones, the algorithm in the television that controls these zones is unable to respond adequately — in this case, it strongly dims small elements like the moon or the light from a helicopter. Bright light that should dazzle us is too dim to be considered an HDR effect. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 colour gamut, at 96%, which allows it to accurately render most film scenes.

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

The Chinese manufacturer offers various picture settings in its televisions, but the best mode in this model is undeniably the Filmmaker Mode. Despite its name, this mode has its issues: the white balance, although roughly correct, is characterised by a strong dominance of warm tones due to the prominence of red hues, both in 4K and HD material. The Colour Checker test confirms these errors — deviations in samples can be seen in improper shades. As for brightness characteristics, the gamma responsible for HD material shows values below 2.4, which leads to some screen brightness. Meanwhile, the EOTF curve shows the television's problems with displaying small light elements, as confirmed by the previously described paragraphs.

TCL C75B offers various picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the TV struggles with certain colour reproduction issues. In tests, we noticed that the image had a noticeably pinkish hue compared to what could be considered correct. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit of this phenomenon turned out to be the white balance, characterised by an excess of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was reproduced. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described in the next section.

Hisense TVs offer a range of image correction tools that allow you to adjust settings to your own preferences, which is why we decided to use these capabilities to bring the image quality closer to reference standards. In terms of white balance, we were able to eliminate the dominance of red, resulting in more neutral colours, which allowed for a more realistic image in both 4K and HD content. We noticed a similar improvement in brightness characteristics. The gamma, which previously led to excessive brightness on the screen, has been corrected, contributing to better detail reproduction in darker areas of the image while maintaining natural tonal balance.

However, the biggest challenge was calibrating the EOTF curve, which is responsible for brightness in 4K content. At first glance, the EOTF value looked almost perfect, but detailed tests revealed somewhat different results. When we looked closer — especially using the filter on the right side of the EOTF chart — we noticed how the TV manipulated 4K film content, often significantly boosting brightness. This effect was particularly noticeable in scenes from films like Pan and Billy Lynn, where the TV attempted to artificially increase the brightness of elements, impacting their naturalness. Despite these imperfections, the calibration yielded positive results, especially in terms of tonal improvement. For most users, the end result should be satisfying, particularly if they are looking to bring image quality closer to professional reference standards.

After calibration, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant to watch.

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

TCL C75B has a feature for smoothing tonal transitions, but unfortunately, we cannot praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature wasn’t working at all. It’s hard to say anything positive about it, as in practice it seems completely useless.

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

Hisense U7NQ has a refresh rate of 144 Hz, which definitely enhances motion smoothness. For movie enthusiasts, there are two features available: judder reduction and motion blur reduction. The judder reduction function minimises the effect of so-called judder, that is, unpleasant image jumps, particularly noticeable at lower frame rates. Meanwhile, motion blur reduction helps to sharpen fast-moving objects, which is useful when watching dynamic action scenes.

When it comes to trailing, the television has a decent response time, which means excessive trailing is not visible, except in specific situations, such as the test with the alien on a dark background. In such cases, slight artifacts may appear, but overall the television handles dynamic images well, providing satisfying motion quality.

TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

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

The TV also supports Dolby Vision, which is particularly important for gamers who value high contrast and rich colours in games that support this format. The Hisense U7NQ also features a Game Bar, allowing quick access to key settings during gameplay, as well as support for G-Sync technology, further reducing image tearing.

Unfortunately, despite its 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 remaining features make the Hisense U7NQ a solid choice for any console gaming enthusiast.

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.
