Hisense A6N vs TCL P755

The quality of the HDR effect on A6N unfortunately does not impress. The peak brightness of 250 nits does not allow for spectacular effects, and HDR appears rather dull, resembling more of a regular SDR. This state of affairs will not satisfy more demanding users who wish to enjoy high-quality film materials. Additionally, the coverage of the colour palette is also not very impressive – a DCI-P3 level of 82% is an average result that does not fully allow one to enjoy vibrant colours in HDR materials.

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.

In the category of colour reproduction, the model Hisense A6N in Filmmaker Mode leaves much to be desired. Although the name of the mode suggests that we should expect faithful reproduction of cinematic colours, the reality is different – the television has significant issues with image quality. The problem with white balance is particularly noticeable, both for HD and 4K materials, which is heavily disrupted by the dominance of blue. This results in artificial, cold tones, which can clearly be seen in the comparison photo below. The Colour Checker test further confirms these errors, which are exacerbated by low colour gamut coverage.

The gamma brightness characteristic shows a serious problem in maintaining a level of 2.4 – the graph is significantly below the reference value, which leads to excessive image brightness and washed-out blacks. The EOTF curve for 4K materials also indicates brightness issues – at the beginning, there is a significant spike, which results from the television's excessive brightness, negatively impacting image quality. Such image characteristics do not allow one to fully enjoy watching films and require manual correction.

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.

Hisense A6N offers options and tools in its settings to adjust many image parameters that we have utilized. When it comes to white balance, we managed to eliminate the excess blue colour – this effect is clearly visible in the comparison photo below, where the boy in the image seemingly "comes to life". A significant improvement can also be noticed in the gamma brightness characteristics – the television no longer has serious issues with excessively brightening the entire image. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to the exceptionally low brightness of this model. For HDR materials, we apply dynamic tone mapping, which allows for the recovery of many details despite the boosting of mid-tones in the image. For this television, this provides more benefits than drawbacks. The errors that are still visible in the colour palette test and Colour Checker for 4K materials stem from the low colour gamut coverage and are difficult to eliminate due to the characteristics of the television. Nevertheless, the tonal quality of the image is significantly better, which is why we recommend calibrating the factory settings, which are far from ideal.

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.

Let's check how A6N performs with low-quality materials. When it comes to smoothing tonal transitions, the lack of posterisation reduction or smoothing of tonal transitions in low-quality materials such as television or DVD can be noticeable for more demanding viewers. In terms of digital processing, the model is presented correctly, and the branches are devoid of characteristic jaggedness – the image is very plastic and soft, which may appeal to those who prefer this style of image.

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 60 Hz panel in the Hisense A6N will likely satisfy those who enjoy watching films, as the television offers an "ultra motion smoother," allowing us to adjust the motion smoothness – either more choppy or more fluid, cinematic. When it comes to motion blur, it performs rather average – noticeable blur is evident, especially on dark backgrounds, which is quite a typical feature in this range of televisions.

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).

Hisense A6N is a television that is likely to appeal to casual gamers, primarily due to its 60 Hz panel, which may not satisfy more demanding users. Nevertheless, it offers several features that can enhance the gaming experience. The television supports functions such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Dolby Vision, which allows for better picture quality and smoother motion in games that support these technologies. Moreover, the low input lag ensures quick reactions in gameplay, which is crucial, especially in dynamic productions. With these features, although the television is not an ideal choice for demanding gamers, it provides solid support for those who appreciate comfortable gaming without complicated settings. It is an ideal solution for individuals who want to enjoy gaming without high hardware requirements while also having access to modern technologies that enhance gameplay quality.

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.
