Hisense U7NQ vs TCL C655 / C69B (55"-85")

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.

Overall, the quality of the HDR effect in TCL C655 / C69B looks quite promising. The average value in the test patterns is around 450 nits, which already allows you to feel the light effects and better image dynamics. However, as mentioned earlier, this effect may be somewhat subdued by slight differences in bright and dark shades, resulting from the lack of local dimming technology. However, the DCI-P3 colour gamut coverage of 94% deserves high praise, and this is possible due to the use of a quantum dot (QLED) panel. This makes the colours vibrant and well-reproduced when watching HDR content.

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.

The TCL C655 / C69B television offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has quite a few errors that the director would certainly not want to see when filming their work. Starting with image analysis, it's worth looking at the white balance – both in HD content and 4K HDR, the white balance has significant issues. In both cases, the red colour dominates, resulting in colours that are too warm, with an overall pink or yellow tint. This can be seen in the image below from the film "Star Wars." The Colour Checker test confirms these errors – the colour samples stray into incorrect shades, affecting the overall colour fidelity. The brightness characteristics are a lesser issue. However, they are not without flaws either. The gamma chart shows a strong spike at the beginning, which can cause the image to be overly bright, and the EOTF curve responsible for brightness in 4K HDR content also has significant fluctuations – it's evident how the television tries to maintain appropriate brightness, but it doesn't always succeed effectively.

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 movie mode of the television TCL C655 / C69B , the white balance has been adjusted, and the colours look as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really good, which ensures that the television shouldn't have any issues with brightness in low-resolution material. Unfortunately, a similar EOTF characteristic is still noticeable, which is a natural occurrence in televisions that do not have local dimming – they simply struggle to "shine" brighter in a given part of the screen. Despite this design limitation, which cannot be bypassed, we recommend making adjustments in the settings, as the overall colour presentation looks really very good.

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.

Television TCL C655 / C69B handles tonal transitions in low-quality materials fairly well. The "Gradual Smoothing" feature on low settings effectively smooths out tonal transitions, but it also blurs important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps to maintain the natural look of the image. In terms of digital processing, the television adds artificial sharpness, which some users who prefer a sharper image might appreciate. However, for those who prefer a softer look, this may be a drawback. Another downside is that the image has been significantly cropped due to the so-called overscan, which reduces the field of view and cuts off the edges of the image.

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 television C655 / C69B is equipped with a 4K@60 Hz panel, which means it's best suited for watching movies and less dynamic content. It also features a "Flicker Reduction" function, allowing users to adjust the smoothness of the image – they can choose whether they prefer smoother motion or a more cinematic, frame-like effect. The television can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will surely please gamers by offering a smoother image at the cost of resolution. It’s worth noting that this feature is available in sizes starting from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

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 / C69B TV offers an almost perfect set of features for gamers, supporting all the key technologies. It has an ALLM feature that automatically switches the TV to low latency mode, significantly improving responsiveness and minimising signal lag, which is especially important during dynamic gameplay. The VRR feature allows synchronisation of the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay.

The TV also supports Dolby Vision in gaming mode, ensuring better colour and contrast reproduction in games that support this format, and the Game Bar enables quick access to gameplay-related settings, such as response time, latency level, and other parameters. Unfortunately, the C655 / C69B does not support 4K resolution at 120 Hz (the 98" variant is the exception), which may be disappointing for more demanding gamers seeking the ultimate smoothness in high-resolution games. However, if we can forgo 4K, the TV offers support for Full HD and 2K at 120 Hz, providing a smoother image and serving as a great alternative for those who prefer higher refresh rates at the expense of resolution.
