TCL P755 vs Hisense A7NQ

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.

We checked how the Hisense A7NQ performs with HDR, and there are no surprises here. The luminance graph showed a maximum brightness level of 370 nits. The result? Exactly what one could expect – average. At around 350 nits, HDR does not particularly stand out compared to SDR. Indeed, there is a subtle difference in more brightly lit scenes, but it is not an effect that leaves you stunned. As for the coverage of the wide colour gamut, 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 is sometimes promoted as QLED. Colours look good, but we shouldn’t expect something that competes with the best screens on the market. HDR on the Hisense A7NQ is more of an addition than a "game changer." For those looking for solid image quality on a moderate budget – quite acceptable. However, if we expect full HDR capabilities, it is worth looking at models from the higher price range.

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.

When testing the Hisense A7NQ in Filmmaker mode, we were hoping for compliance with the manufacturer's assumptions, but unfortunately, reality looks different. The main issue, as with most televisions, is 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 results of the Color Checker tests confirm this, and the comparative images speak for themselves – the leading actress in "factory" mode appears cool and pale. It looks as if she has been drained of life.

As for brightness characteristics, both gamma and the EOTF curve show that the image is excessively bright. As a result, everything appears flat, lacking depth and contrast. This state of affairs definitely does not work in favour of the A7NQ and makes the viewing experience 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 is a television that requires considerable adjustment to bring out its potential.

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.

Hisense A7NQ offers several tools that allow for improved image quality, so we decided to take matters into our own hands and "dig around" in the settings a bit. Thanks to professional tools and measurements, we managed to correct the white balance, eliminating the excessive dominance of blue colour in both HD and 4K materials. This is a significant step forward, as in the Color Checker test, the colour reproduction errors in lower quality content dropped to a much more acceptable level. Unfortunately, the 4K materials still fall short of perfection – the colour inaccuracies are considerable 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 brightness characteristics in 4K content remains unresolved – the EOTF curve still shows excessive brightness across the entire screen. It’s possible that correct implementation of dynamic tone mapping could help here, but as we mentioned earlier, this feature in the Hisense A7NQ works rather poorly, rather than being helpful. Nevertheless, the calibration has significantly improved the overall image reception. The director's vision is now much better represented than in the factory settings, which will certainly be appreciated by more demanding viewers.

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.

The Hisense A7NQ impresses with the smoothness of tonal transitions in 4K content, but unfortunately, there is no feature here to improve this aspect in older materials of lower quality. In such cases, colour transitions become more visible, which can slightly detract from the overall image, especially in scenes with a lot of gradients.

When it comes to upscaling, the television performs surprisingly well. The image is noticeably improved, although there are some compromises. It can be seen that the television adds a bit of artificial sharpness, and background elements, such as branches, display slight "jaggies." However, these are details that will primarily catch the eye of those who pay attention to such nuances.

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).

The Hisense A7NQ is equipped with a 60 Hz panel, which means that dynamic scenes – for example in sports or games – perform rather averagely here. This is standard for this class of equipment, but it must be acknowledged that watching more intense, fast-moving content can leave a lot to be desired. However, when it comes to films, the television offers a motion smoothing feature that operates on a 10-point scale. The "judder reduction" option allows you to tailor the smoothness of the image to your own preferences. At the lowest setting, we get a natural film frame rate, which will please cinema purists. Meanwhile, the maximum setting provides a very smooth, theatrical image that may appeal to those who prefer a more "smoothed" 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 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.

Hisense A7NQ is a piece of equipment that can pleasantly surprise gamers, although it is not without its flaws. The fact that we have a 60 Hz panel here immediately suggests that the television is not designed for the most demanding gaming scenarios. The motion blur that we described earlier can also be an obstacle, especially in dynamic games.

However, there are a few things that are worth praising. The television supports ALLM (automatic game 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 images at 120 Hz – albeit only in Full HD resolution, but nevertheless, it's a significant nod to gamers. This provides the option to choose between smoothness and resolution, which is not obvious in televisions at this price.

A nice addition is the Game Bar, which is clear and practical – all the most important functions are at hand, without digging through the settings. However, it lacks support for HGiG, which may be a disappointment for gamers looking for perfect HDR in games.
