TCL P755 vs Hisense U7Q PRO

TCL P755 provides average HDR effect quality. The maximum brightness of the TV is slightly below 300 nits. Such brightness limits the intensity of bright areas in HDR content. In practice, this means that bright elements may not be sufficiently pronounced, affecting the overall impression of contrast. However, the TV offers wide coverage of the DCI P3 colour gamut, reaching about 93%. As a result, colours are vibrant and saturated, significantly improving colour reproduction quality in HDR content. Despite the limited brightness, the wide colour range allows for richer and more realistic shades.

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 colour reproduction in the P755 in "Cinema" mode, although it is the best factory setting, leaves much to be desired. The biggest issue is the white balance, where the chart clearly shows a spike in the red colour and a drop in the green colour. This leads to a shift in colours towards red, causing the colours on the screen to appear less natural and may look incorrect, especially in scenes with a white or neutral background. This is confirmed by the "Colour Checker" test, which reveals that the colours are indeed shifted towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows significant fluctuations, particularly in the dark areas of the image, where values drop below the optimal level of 2.4. As a result, darker areas may be displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, sits slightly above the reference curve. The graph shows a slight increase in brightness to about 50%, after which there is only a minor drop. This leads to excessive brightness enhancement in the mid-range of the image and may result in loss of detail and distortion in brighter scenes.

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 calibration, the colour reproduction on the television significantly improves when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the dip at the beginning of the graph to the values is still present, the overall accuracy of colour reproduction is much better. The “Colour Checker” test shows that most colour samples have errors below level 2, indicating improved colour fidelity. A few deviations are present, but generally, the colours are now more realistic and consistent with reality.

Calibration also brings improvements in HDR content. The white balance has been corrected, translating to more natural colour reproduction. The EOTF curve, although now closer to the reference curve, still shows a slight boost in brightness at the beginning of the graph. This leads to minor distortions in very bright scenes, but the overall tonality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and preserving more details.

Although the image from the device does not achieve full perfection, calibration brings significant improvement. After adjusting the settings, the television performs much better, offering more realistic and accurate colour reproduction in SDR and HDR content. While some shortcomings can still be noticed, calibration effectively eliminates many previous issues, ensuring better image quality and more natural colours.

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 “Gradual Smoothing” function works quite well, effectively eliminating visible boundaries between different shades of the same colour. Thanks to it, tonal transitions are smoother. Unfortunately, this function is not available in HDR mode, which can affect the quality of tonal gradation in higher dynamic range materials.

In the case of image scaling, the television does not perform its best. There are noticeable edge cut-offs, particularly evident on the model's figure and the branches of trees. The blurring of details in these areas affects the overall sharpness of the image. This may be noticeable when watching content in a lower resolution. Additionally, SD quality image is displayed with slight cropping at the top as well as the bottom.

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 offers decent, though not perfect, results in terms of motion smoothness. In the case of movies, the television has a "Flicker Reduction" feature that allows for adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the image appearance to cinema or more theatrical preferences (with lower or higher speed).

“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 device offers a range of features useful for gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the TV to low latency mode, significantly improving responsiveness to commands from the controller and minimising input lag. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating the tearing effect and providing smoother gameplay. Dolby Vision for gamers enhances picture quality by offering better colour and contrast reproduction in games that support this format. The Game Bar feature allows quick access to game settings and monitoring of key parameters such as response time.

However, the TV has some limitations. The 60 Hz panel prevents the display of signals with higher refresh rates at different resolutions, which may affect the fluidity of the image in dynamic games. Additionally, the lack of support for G-Sync technology for PC may impact the quality of gameplay on a computer. It is also worth noting that the HGiG mode, which aims to improve image quality in HDR games, does not work correctly on this model, negatively affecting the visual experience in HDR-supported games.

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.
