Hisense U7NQ vs TCL C655 Pro

The Hisense U7NQ 65 television demonstrated significant capabilities on the luminance chart, exceeding the 1000-nit barrier and achieving very high brightness results without issue in the first, third, and fifth test scenes. However, as before, in the second and fourth test scenes, for example from the film Sicario 2, there are significant problems with maintaining brightness, and the results around 200 nits are very disappointing. Despite a large number of dimming zones, the algorithm in the television responsible for controlling these zones is unable to react appropriately — in this case, it significantly dims small elements like the moon or the light from a helicopter. The bright light that should blind us is too dim to be called an 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 accurately reproduce most film scenes.

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

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

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with the TCL 655 PRO model.

In the case of HD content, the white balance clearly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation looks better, but there is a tendency to excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

Hisense televisions offer many tools for image correction, allowing users to adjust settings to their preferences. Therefore, we decided to utilize these capabilities to bring the image quality closer to reference standards. In the case of white balance, we managed to eliminate the dominance of red, resulting in more neutral colours, which allowed for a more realistic image in both 4K and HD materials. A similar improvement was noticed in the brightness characteristics. Gamma, which previously led to excessive screen brightness, was corrected, contributing to better detail representation in the darker areas of the image while maintaining a natural tonal balance.

However, the biggest challenge was the calibration of the EOTF curve, which is responsible for brightness in 4K materials. At first glance, the EOTF value appeared almost perfect, but detailed tests showed a slightly different outcome. Upon closer inspection—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, especially if they aim to bring image quality closer to professional reference standards.

After calibrating the TCL 655 PRO television, a noticeable improvement in white balance can be observed, having completely eliminated the tendency for the screen to have an excessive pink hue, which was previously visible in factory mode. The image has taken on more natural tones, especially in white and bright elements, positively affecting the overall perception of the picture. As for brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image look washed out. Nevertheless, there are still some issues with the EOTF curve that are difficult to eliminate due to the design of the television and its limited number of dimming zones. These limitations prevent achieving ideal results in this regard. However, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high image quality and very good color reproduction.

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 well, and the branches in the background are not excessively jagged — the image seems quite plastic. However, it was slightly cropped by the so-called overscan.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

Hisense U7NQ has a refresh rate of 144 Hz, which definitely contributes to smooth motion. For movie enthusiasts, there are two features available: judder reduction and motion blur reduction. The judder reduction feature minimizes the effect of so-called judder, which is the unpleasant stuttering of the image, particularly noticeable at lower frame rates. On the other hand, motion blur reduction helps sharpen fast-moving objects, which is useful when watching dynamic action scenes.

As for motion blur, the TV has a decent response time, so excessive blurriness is not visible, except in specific situations, such as the test with the little green alien on a dark background. In such cases, slight artifacts may appear, but overall, the TV handles dynamic images well, providing satisfactory motion quality.

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

Hisense U7NQ offers everything a gamer might need for comfortable gameplay. The TV 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 changing frames per second, eliminating stuttering and tearing. Additionally, there is an ALLM (Auto Low Latency Mode) feature that automatically switches the TV to game mode, minimizing input lag.

The TV also supports Dolby Vision, which is particularly important for gamers who value high contrast and vivid colors in games that support this format. The Hisense U7NQ also has a Game Bar feature that allows quick access to essential settings during gameplay, as well as support for G-Sync technology, which further reduces image tearing.

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

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.
