TCL P755 vs Hisense U7Q PRO

TCL P755 provides average HDR effect quality. The maximum brightness of the television 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, which affects the overall impression of contrast. However, the television offers a wide coverage of the DCI P3 colour gamut, reaching around 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 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 colour reproduction in the P755 in "Movie" mode, although it is the best factory setting, leaves much to be desired. The biggest problem is the white balance, where the graph clearly shows a spike in red and a drop in green. This leads to a shift in colours towards red, making the colours on the screen less natural and potentially looking 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 skewed towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows considerable fluctuations, particularly in dark areas of the image, where values drop below the optimal level of 2.4. This results in darker areas being displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, is slightly above the reference curve. The graph shows a slight boost in brightness to around 50%, followed by only a minor decrease. This leads to excessive brightness enhancement in the mid-tones 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 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 calibration, the colour reproduction on the television improves significantly when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the drop at the beginning of the graph to value 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 improvement in HDR content. The white balance has been improved, resulting in a 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 tonal quality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and retaining more detail.

Although the device's picture does not achieve complete perfection, calibration brings significant improvement. After adjusting the settings, the television presents itself much better, offering a 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 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 "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 may affect the quality of tonal gradations in higher dynamic range materials.

When it comes to image scaling, the television does not perform at its best. There are noticeable edge cuts, particularly evident on the figure of the model 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. Moreover, SD quality images are displayed with slight cropping at the top as well as the bottom.

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 offers decent, although not perfect, results in terms of motion fluidity. For films, the television features a “Flicker Reduction” function that allows for motion fluidity adjustment on a scale from 1 to 10. With this option, we can customise the appearance of the image to a cinematic or more theatrical preference (with a slower or faster pace).

“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 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 television to low latency mode, significantly improving response 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 screen tearing and providing smoother gameplay. Dolby Vision for gamers enhances picture quality, 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 reaction time.

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

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.
