TCL C655 Pro vs Hisense U7Q PRO

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.

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%.

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.

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 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.

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.

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.

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 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.

“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 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.

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.
