Hisense U7NQ vs TCL C655 Pro

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.

In the HDR effect quality category, the television TCL 655 PRO shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoying HDR effects, which can be clearly seen in scenes such as the first one from the movie Life of Pi or the final shot from The Meg. However, the limited number of dimming zones causes some issues. 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 more. The dimming algorithm aims for deep blacks, but at the cost of brightness – which at those moments can cause a drop in brightness of even half. In these more challenging scenes with small elements, it's hard to find any praise, and the HDR effect resembles SDR. Nevertheless, the coverage of the colour palette deserves recognition, which, like in the version without the PRO suffix, is at a very good level.

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.

Each of our TV tests is conducted in movie mode, which usually offers the best colour reproduction. However, even this mode is not free from issues, as we noted in 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 overly emphasise the colour blue. As a result, the image can give a sense of artificial sharpness, which proves to be uncomfortable for the eyes over a longer period. The brightness characteristics also leave much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, making the overall presentation appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we have detailed in the paragraph regarding HDR effects.

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 calibrating the TCL 655 PRO television, there is a noticeable improvement in white balance, where the tendency for the screen to be overly pink has been completely eliminated, which was previously noticeable in factory mode. The picture has taken on more natural tones, especially in white and bright elements, which positively affects the overall image perception. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image appear washed out. Nevertheless, there are still some issues with the EOTF curve, which are difficult to eliminate due to the television's construction and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. However, despite this minor fault, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour 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 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.

The TCL 655 PRO television handles tonal transitions quite well in lower-quality material. The "Gradual Smoothing" feature at low settings effectively smooths tonal transitions, but this comes at the cost of losing some essential details, such as the texture of objects. On the plus side, it doesn't negatively affect film grain, which helps maintain a natural look to the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a bolder image. However, individuals who favour a softer, more subtle look may find this a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and cuts off the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

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.

The TCL C655 PRO television is equipped with a 4K display with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows for adjusting the smoothness of the picture, giving the user the choice between smoother motion and a cinematic, frame-by-frame effect. Furthermore, the television performs well with lower resolution content, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will surely appeal to gamers who can enjoy a smoother image, 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 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.

The TCL C655 PRO TV offers an almost perfect set of features for gamers, supporting all key technologies that significantly enhance gameplay comfort. The ALLM feature automatically switches the TV to low-latency mode, improving responsiveness and minimising signal delay – particularly important in fast-paced titles. VRR synchronises the screen refresh rate with the frame rate generated by the console, eliminating screen tearing and ensuring smoother gameplay.

Support for Dolby Vision in game mode enables more detailed colour and contrast representation in games that support this format, while the Game Bar provides quick access to essential settings, such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for high refresh rate enthusiasts.
