TCL P755 vs Hisense A7NQ

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.

We checked how the Hisense A7NQ performs with HDR, and there's no surprise here. The luminance chart showed a maximum brightness of 370 nits. The result? Exactly what one could expect – average. At around 350 nits, HDR doesn’t stand out much compared to SDR. Sure, there’s a subtle difference in more brightly lit scenes, but it’s not a show-stopping effect. In terms of wide colour gamut coverage, the result was 92% for DCI-P3 and 70.2% for BT.2020. These are decent values for a TV in this class, which uses a PFS coating – the same one that’s sometimes promoted as QLED. The colours look alright, but don’t expect something that competes with the best screens on the market. HDR on the Hisense A7NQ is more of an add-on than a "game changer". For those looking for solid image quality on a moderate budget – it’s definitely acceptable. However, if we expect full HDR capabilities, it’s worth looking at models from the higher price range.

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.

When testing the Hisense A7NQ in Filmmaker mode, we hoped for alignment with the manufacturer's intentions, but unfortunately, reality looks different. The main issue, as with most TVs, is the white balance. In the case of the A7NQ, we noticed a clear dominance of blue, which affected both lower-quality materials and 4K HDR content. The Color Checker test results confirm this, and the comparative images speak for themselves – the lead actress in "factory" mode looks cool and pale. It appears as though she has been stripped of life.

As for brightness characteristics, both gamma and the EOTF curve show that the image is overly bright. As a result, everything seems flat, lacking depth and contrast. This state of affairs certainly does not work in favour of the A7NQ and makes the image reception in factory mode leave much to be desired. If we expect natural colour reproduction and appropriate image depth, the A7NQ in Filmmaker mode is unlikely to impress us. It’s a TV that requires significant adjustment to bring out its potential.

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.

Hisense A7NQ offers several tools that allow you to improve image quality, so we decided to take matters into our own hands and do some "digging" in the settings. Thanks to professional tools and measurements, we managed to correct the white balance, eliminating excessive dominance of blue in both HD and 4K content. This is a significant step forward, as in the Color Checker test, the errors in colour reproduction in lower-quality content dropped to a much more acceptable level. Unfortunately, 4K content still falls short of perfection – colour distortions are significant here and stem from the limitations of the television.

As for the gamma, we managed to set it at the correct level, which significantly reduced the excessive brightening of the image. However, the issue with the brightness characteristics in 4K content remains unresolved – the EOTF curve still shows excessive brightness across the entire screen. It's possible that a proper implementation of dynamic tone mapping could make a difference here, but as we mentioned earlier, this feature in Hisense A7NQ works rather poorly, instead of helping. Nevertheless, the calibration significantly improved the overall image perception. The director's vision is now much better represented than in the factory settings, which more demanding viewers will definitely appreciate.

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.

The Hisense A7NQ impresses with its smooth tonal transitions in 4K content, but unfortunately, we won't find any features here that improve this aspect in older, lower-quality materials. In such cases, colour transitions become more noticeable, which can slightly detract from the overall picture quality, especially in scenes with a lot of gradients.

When it comes to upscaling, the television performs surprisingly well. The image is clearly improved, though it comes with certain compromises. It can be seen that the TV adds a touch of artificial sharpness, and background elements, like branches, tend to exhibit slight "jaggies." However, these are details that will mainly catch the eye of those who pay attention to such nuances.

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).

The Hisense A7NQ is equipped with a 60 Hz panel, which means that dynamic scenes – for example in sports or gaming – come across as rather average here. This is standard in this class of equipment, but it's worth noting that watching more intense, fast-moving content can leave a lot to be desired. However, when it comes to movies, the TV offers a motion smoothing feature that works on a 10-point scale. The "judder reduction" option allows you to adjust the smoothness of the image to your own preferences. At the lowest setting, you get a natural film frame rate, which will appeal to cinema purists. Conversely, the maximum setting provides a very smooth, theatrical image, which may be appreciated by those who prefer a more "smeared" motion.

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 A7NQ is a piece of gear that may pleasantly surprise gamers, although it's not without its flaws. The fact that it has a 60 Hz panel immediately suggests that the TV is not designed for the most demanding gaming scenarios. The motion blur we mentioned earlier can also be a drawback, especially in fast-paced games.

However, there are a few things worth praising. The TV supports ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), which is not always standard in this price range. The biggest surprise, however, is that the A7NQ can display visuals at 120 Hz – albeit only in Full HD resolution, but it's still a significant nod to gamers. This provides the option to choose between smoothness and resolution, which is not obvious in TVs at this price.

A nice addition is the Game Bar, which is clear and practical – all the essential features are at hand without having to dig through the settings. However, it lacks support for HGiG, which could be a disappointment for gamers seeking perfect HDR in games.
