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

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.

U7Q PRO is truly a bright television. In synthetic tests, it achieved over 1500 nits, which is an outstanding result for this price bracket. Such brightness – at least in theory – allows it to display HDR content as intended by the creators, even in more demanding scenes with strong lighting. In practice, it performs very well, but not always perfectly. In bright scenes with large areas – like the test screen with intense sunlight from the film "Pan" – the U7Q PRO makes a huge impression. It can even dazzle with its light, which is definitely an advantage in the context of HDR content. Unfortunately, it doesn’t always manage to maintain this when there are many small bright details on a dark background. In such moments, the local dimming algorithms tend to dim some bright elements to maintain good blacks – and the side effect is that some details simply vanish from the frame. This is a classic compromise in mini-LED televisions – and the U7Q PRO is no exception. With such a large number of dimming zones, however, one could have hoped for a slightly more mature algorithm responsible for their control. Fortunately, the overall perception of HDR content is very 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%, and BT.2020 around 73%.

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.

We tested the U7Q PRO in the best possible picture mode that this model offers – Filmmaker Mode. And indeed, this mode performs the best in terms of colour reproduction. But 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 shifted towards blue, which made the overall image feel a bit "cooler." It may not be glaring, but it is definitely noticeable – particularly on white backgrounds, which instead of being neutral, seemed slightly bluish. 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 charts. All of this together means that without calibration, the image may appear somewhat unnatural – too cool, with slightly exaggerated dynamics. That’s why we decided to perform our own calibration – and you can see its effects and charts below.

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.

Thanks to calibration, we've managed to tame the white balance in SDR and HDR content. For SDR material, the effect is really quite good – the image becomes neutral, cohesive, and simply pleasant to watch. Everything looks the way it should.

HDR performs a bit worse. Although the white balance looks correct and overall the image gains naturalness, unfortunately, the delta E errors are still noticeable. Why? Because Hisense's U7Q PRO model does not give us full control over how the television manages brightness in HDR mode. And this is where the limitation arises. When we look at the EOTF curve for HDR content, it clearly shows what we mentioned earlier – at the beginning of the graph, there’s a noticeable drop, meaning the television darkens the smallest portions more than it should. On the other hand, those brightest elements can be overly bright. As a result, some details are lost, others are too aggressive, and overall control over brightness doesn't always align with what we’re trying to achieve during calibration.

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

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.

If someone happens to come across older materials where the banding issue arises – Hisense has a solution for that. In the U7Q PRO, we find a feature called "Smooth and Gradient Picture". Set to the "Medium" level, it works really well – eliminating most gradient problems without smoothing the entire image like a blur in Photoshop. 😉 Film grain remains, details don't disappear – that's exactly how it should work. Well done on the implementation!

As for scaling weaker materials, it's simply good. It's not at the level of the most expensive TVs with advanced upscaling, but older content looks good. There is some minor banding at very low resolutions, but that's perfectly normal and hard to avoid. On the plus side – even with the oldest materials, there is no overscan effect, the image isn't cropped or artificially stretched.

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.

“Speed” – this word was most frequently mentioned during our tests of the U7Q PRO. The television is equipped with a 165 Hz panel, which in itself is impressive – especially considering we’re talking about a mid-range model. Of course, PC gamers will benefit the most from its full capabilities, but even during everyday viewing, it’s clear that this is a fast and efficient panel. Like most modern televisions, the U7Q PRO can also enhance the smoothness 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 feel, with subtle motion, to a stronger smoothing with the characteristic “soap opera effect.”

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.

Hisense U7Q PRO is a TV that seems to have been designed with gamers in mind. We have practically everything that can be expected from a gaming screen: variable refresh rate (VRR), automatic mode (ALLM), and as many as four HDMI 2.1b ports with full bandwidth of 48 Gb/s. Additionally, there’s 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 the ideal? Well, almost. Unfortunately, Hisense has still not implemented the HGiG feature, which is the system's tone mapping limitation on the TV's end. This means that when configuring HDR brightness on the console, we do it “by eye” or look for settings in online guides, as the screen does not display its actual brightness range. It’s a shame – because HGiG makes it easier to match the console to the TV and helps avoid overexposed or too dark scenes in HDR games.

Fortunately, the other elements work very well. Input lag is low, responsiveness is excellent, and the handling of other features is faultless. And although not everything worked perfectly, the U7Q PRO can still be confidently recommended to gamers.
