TCL C655 / C69B (55"-85") vs Hisense U7Q PRO

Generally speaking, the quality of the HDR effect on the TCL C655 / C69B looks quite promising. The average value in the test charts is around 450 nits, which already allows one to feel the light effects and better image dynamics. However, as previously mentioned, this effect may be partially subdued by slight differences in bright and dark colours, resulting from the lack of local dimming technology. However, the coverage of the DCI-P3 colour palette at 94% deserves high praise, and this is made possible by the use of a quantum dot (QLED) matrix. As a result, colours are vivid and accurately represented when watching HDR content.

U7Q PRO is truly a bright television. In synthetic tests, it achieved over 1500 nits, which is an outstanding result for this price range. Such brightness – at least in theory – allows for HDR content to be displayed as intended by the creators, even in more demanding scenes with strong lighting. In practice, it is often very good, but not always perfect. In bright scenes with large areas – like the test chart with intense sunlight from the movie "Pan" – the U7Q PRO makes a huge impression. It can almost dazzle with its brightness, which is definitely an advantage in the context of HDR content. Unfortunately, it doesn't always manage to maintain this when many small bright details appear on a dark background. In such moments, the local dimming algorithms choose to dim some bright elements to maintain good black levels – and the side effect is that some details simply disappear from the frame. This is a classic compromise in mini-LED televisions – and the U7Q PRO is no exception. However, with such a large number of dimming zones, one could have hoped for a slightly more mature algorithm responsible for their control. Fortunately, the overall perception of HDR content is decidedly positive. The U7Q PRO is not only bright but also colourful, thanks to the PFS LED (QLED) coating, the coverage of the DCI-P3 colour palette is at 95%, while BT.2020 is around 73%.

The television TCL C655 / C69B offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has several errors that a director would surely not want to see when recording their work. Starting with image analysis, it is worth examining the white balance – both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red colour dominates, causing the colours to be too warm, and the overall result takes on a 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 veer into incorrect shades, affecting the overall colour fidelity. A less significant issue is the brightness characteristic. However, this is also not without its flaws. The gamma graph shows a strong peak at the beginning, causing the image to be excessively brightened, and the EOTF curve responsible for brightness in 4K HDR material also has substantial fluctuations – it is noticeable how the television tries to maintain the appropriate brightness, but it does not always succeed effectively.

We tested the U7Q PRO in the best possible picture mode offered by this model – Filmmaker Mode. And indeed, this mode performs the best in terms of colour reproduction. However, that doesn't mean it's perfect. In our test unit, both in SDR and HDR content, the image had a slightly cooler tone. The white balance was skewed towards blue, giving the overall impression of being a bit "colder". It may not be glaring, but it is definitely noticeable – especially on white backgrounds, which seemed slightly bluish rather than neutral. Additionally – as we mentioned earlier – the television has a tendency to slightly brighten and oversaturate the image, which is also confirmed by the gamma and EOTF graphs. All this together means that without calibration, the image can appear somewhat unnatural – too cool, with slightly exaggerated dynamics. Therefore, we decided to carry out our own calibration – and you can see its effects and graphs below.

After calibrating the television's film mode TCL C655 / C69B , the white balance has been adjusted, and the colours are presented as they should be – confirmed only by slight deviations in the Colour Checker test. The gamma is really quite accurate, which means the television should not have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still visible, which is a natural phenomenon in televisions that do not have local dimming – they simply struggle to "shine" more in a given area of the screen. Despite this inherent limitation that cannot be bypassed, we recommend adjustment in the settings, as the overall colour presentation looks really very good.

Thanks to the calibration, we managed to tame the white balance in SDR and HDR content. In the case of SDR materials, the effect is really very good – the image becomes neutral, cohesive, and simply pleasant to take in. Everything looks as it should.

HDR performs a bit worse. Although the white balance appears correct and the image overall gains in naturalness, unfortunately, the delta E errors remain noticeable. Why? Because Hisense does not give us full control over how the television manages brightness in HDR mode with the U7Q PRO model. This is where the limitation comes into play. When we look at the EOTF curve for HDR content, we can clearly see what we mentioned earlier – at the beginning of the graph, there is a distinct drop, meaning the television darkens the smallest areas more than it should. On the other hand – the brightest elements can sometimes be overly bright. As a result, some details get lost, others are too aggressive, and overall control over brightness does not always match what we are trying to achieve during calibration.

Does the image look better after calibration? Definitely yes, in terms of colour. But when it comes to managing brightness in HDR, we have to accept that the Hisense U7Q PRO will do it in its own way.

The television TCL C655 / C69B handles tonal transitions fairly well in low-quality materials. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, it simultaneously blurs significant details, such as the texture of objects. On the plus side, it does not negatively impact the film grain, allowing the natural appearance of the image to be preserved. As for digital processing, the television adds artificial sharpness, which may appeal to some users who prefer a sharpened image. However, for those who prefer a softer look, this could be a disadvantage. A notable downside is that the image has been quite significantly cropped due to what is known as overscan, which reduces the field of view and trims the edges of the image.

If someone happens to come across older materials where the colour banding issue occurs – Hisense has a solution for that. In the U7Q PRO, we find a function called "Smooth and Gradient Image". Set to the "Medium" level, it works really well – removing most issues with gradation while not smoothing out the entire image, like blurring in Photoshop. 😉 Film grain remains, details do not disappear – this is exactly how it should work. Well done on the implementation!

As for upscaling weaker materials, it is simply good. It is not at the level of the most expensive televisions with advanced upscaling, but older content looks good. There is minor aliasing at very low resolutions, but this is completely normal and hard to avoid. On the plus side – even with the oldest materials, there is no overscan effect, the image is neither cropped nor artificially stretched.

The television C655 / C69B is equipped with a 4K@60 Hz panel, which means it works best for watching films and less dynamic content. It also features a "Flicker Reduction" function that allows for the adjustment of image smoothness – the user can choose whether they prefer smoother motion or a more cinematic, frame-by-frame 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 is worth noting that this feature is available in sizes from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

“Speed” – this word came up most often during our tests of the U7Q PRO. The television is equipped with a 165 Hz panel, which is impressive in itself – especially since we are talking about a model in the mid-range price category. Of course, PC gamers will benefit the most from its full capabilities, but even with everyday viewing, it's clear that this is a fast and efficient panel. Like most modern televisions, the U7Q PRO can also enhance the fluidity of films that were originally recorded at 24 frames. In the menu, we find a slider that allows us to adjust the effect to our own preferences – from a more cinematic look, with subtle motion, to stronger smoothing with the characteristic “telenovela effect.”

The TCL C655 / C69B television offers nearly the perfect set of features for gamers, supporting all the most important 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 the screen refresh rate to synchronise with the frame rate generated by the console, eliminating screen tearing and providing smoother gameplay.

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

The Hisense U7Q PRO is a television that seems almost designed with gamers in mind. It has practically everything one could expect from a gaming display: variable refresh rate (VRR), automatic low latency mode (ALLM), and as many as four HDMI 2.1b ports with full bandwidth of 48 Gb/s. Additionally, there is a clear and quite functional Game Bar, as well as a well-implemented Dolby Vision GAMING mode that works seamlessly with Xbox Series S and X consoles.

Sounds like perfection? Well, almost. Unfortunately, Hisense has still not implemented the HGiG feature, which means the system limitation of tone mapping on the television side. This means that when configuring HDR brightness on the console, we do it "by eye" or search for settings in online guides, as the display does not show the actual range of its brightness. It’s a pity – because HGiG indeed makes it easier to match the console to the television and helps avoid overexposure or overly dark scenes in HDR games.

Fortunately, the other features work very well. Input lag is low, responsiveness is excellent, and the handling of other functions is impeccable. And while not everything worked perfectly, the U7Q PRO can still be recommended to gamers without hesitation.
