Hisense A6N vs TCL P755

The HDR performance on A6N is unfortunately underwhelming. A peak brightness of just 250 nits doesn't allow for spectacular highlights, and HDR looks rather washed out, more like standard SDR. This won't satisfy more demanding users who want to enjoy high-quality film content. Additionally, colour gamut coverage isn't very impressive either, with DCI-P3 at 82% being a mediocre result that doesn't let you fully enjoy vibrant colours in HDR material.

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.

In the colour reproduction category, the Hisense A6N in Filmmaker Mode leaves much to be desired. Although the mode's name suggests we should expect faithful rendering of cinematic colours, the reality is different, and the TV has considerable picture-quality issues. The problem with white balance is particularly noticeable for both HD and 4K material, with a strong bias toward blue. This results in artificial, cool tones, clearly visible in the comparison image below. The ColourChecker test further confirms these errors, which are compounded by low colour-gamut coverage.

The gamma luminance curve shows a serious problem maintaining a 2.4 target. The curve sits well below the reference value, leading to excessive image brightening and washed-out blacks. The EOTF curve for 4K material also indicates brightness issues, with a significant early overshoot caused by the TV's excessive brightening that negatively affects picture quality. This picture profile prevents fully enjoying films and requires manual adjustment.

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.

Hisense A6N offers options and tools in its settings for adjusting many picture settings that we utilised. When it comes to white balance, we managed to eliminate excess blue – this effect is clearly visible in the comparison image below, where the boy in the picture almost "comes to life." A significant improvement can also be noticed in the gamma brightness characteristic – the television no longer has serious issues with excessively brightening the entire image. Unfortunately, the same cannot be said for 4K materials, where the EOTF curve could not be fully corrected due to the exceptionally low brightness of this model. For HDR content, we use dynamic tone mapping, which allows for the recovery of many details despite the boosting of midtones in the image. For this television, this provides more benefits than drawbacks. The errors that are still visible in the test with the colour palette and Colour Checker for 4K content arise from low colour gamut coverage and are difficult to eliminate due to the television's characteristics. 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 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.

Let's see how A6N handles low-quality sources. When it comes to smoothing tonal transitions, the lack of features for reducing posterisation or smoothing such transitions in low-quality material like television or DVD may be noticeable to more demanding viewers. As for digital processing, the model was presented correctly and the branches were free of the characteristic jaggedness. The picture has strong three-dimensional modelling and a soft look, which may appeal to viewers who prefer this kind of image style.

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 60 Hz panel in Hisense A6N will probably satisfy people who like watching movies, because the TV offers an "ultra motion smoothing" feature that lets you adjust the image's judder, making it more choppy or smoother, with a soap‑opera effect. When it comes to motion blur, it’s rather average; there’s quite noticeable smearing, especially on dark backgrounds, which is a fairly typical trait for this class of TVs.

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).

Hisense A6N is a TV that will likely appeal to casual gamers, mainly because of its 60 Hz panel, which may not satisfy more demanding users. Still, it offers a few features that can make gaming more enjoyable. The TV supports ALLM (automatic low latency mode), VRR (variable refresh rate) and Dolby Vision, allowing for better picture quality and smoother motion in games that support those technologies. What's more, the low input lag means in-game reactions are quick, which is crucial, especially in fast-paced titles. Thanks to these features, although the TV is not an ideal choice for demanding gamers, it offers solid support for those who value comfortable gaming without complicated settings. It's an ideal solution for people who want to enjoy gaming without heavy hardware requirements, while still having access to modern technologies that improve the gaming experience.

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.
