Hisense A6N vs TCL P755

Unfortunately, the quality of HDR effect on A6N is not impressive. A peak brightness of 250 nits does not allow for spectacular effects, and HDR is rather pale, resembling more of a regular SDR. This state of affairs will not satisfy more demanding users who want to enjoy high-quality film materials. Additionally, the color gamut coverage is also not very impressive – DCI-P3 at 82% is an average result that does not fully allow for enjoying vibrant colors in HDR materials.

The TCL P755 delivers an average HDR experience, with a maximum brightness of just under 300 nits. This limitation affects the intensity of bright areas in HDR content, reducing the contrast impact, as bright elements may appear less pronounced. However, the TV compensates with an impressive 93% coverage of the DCI-P3 colour gamut, which brings vibrant, saturated colours that enhance the quality of HDR content. Despite the brightness cap, the extensive colour range enriches hues, providing a more lifelike and visually engaging viewing experience.

In the category of color reproduction, the Hisense A6N model in Filmmaker Mode leaves a lot to be desired. Although the name of the mode suggests that we should expect faithful reproduction of cinematic colors, the reality is different – the television has significant problems with image quality. The issue with white balance is particularly noticeable, both for HD and 4K content, which is heavily skewed by the dominance of blue. This results in artificial, cold tones, as clearly seen in the comparative photo below. The Colour Checker test additionally confirms these errors, which are exacerbated by low color gamut coverage. The gamma brightness characteristic shows a serious problem with maintaining a level of 2.4 – the graph is significantly below the reference value, leading to excessive brightness and washed-out blacks. The EOTF curve for 4K content also indicates brightness issues – at the beginning, there is a substantial peak due to the TV's excessive brightness, which negatively impacts image quality. Such image characteristics do not allow for full enjoyment of watching films and require manual adjustment.

In Cinema mode, the colour reproduction on the TCL P755, while set to the best factory configuration, falls short of ideal accuracy. The primary issue is the white balance, where the red component is notably elevated and the green is reduced. This imbalance shifts colours towards red, making them appear unnatural, particularly in scenes featuring white or neutral tones. This issue is highlighted in the Colour Checker test, which shows a discernible red bias affecting the realism of the image and diminishing the perception of colour depth.

Examining contrast performance, the gamma graph analysis reveals notable inconsistencies, especially in darker areas, where values dip below the target level of 2.4. Consequently, shadows and darker sections are displayed brighter than intended, impacting overall contrast. Furthermore, the EOTF (Electro-Optical Transfer Function) curve, essential for accurate brightness representation, veers slightly above the reference curve. The data shows a boost in brightness up to around 50% before a gradual levelling off. This creates excessive mid-tone brightness, which can lead to loss of detail and some distortion in brighter scenes, ultimately affecting the clarity and immersion of the viewing experience.

Hisense A6N offers options and tools in its settings for correcting numerous image settings that we have utilized. When it comes to white balance, we managed to eliminate the excess blue color – this effect is clearly visible in the comparison photo below, where the boy in the image almost "comes to life." A significant improvement can also be observed in the gamma brightness characteristics – the TV no longer has serious issues with overly 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 content, we use dynamic tone mapping, which allows for the recovery of many details despite the boosting of mid-tones in the image. In the case of this TV, it provides more benefits than drawbacks. The errors that are still visible in the color palette test and Colour Checker for 4K materials stem from low color 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 that are far from ideal.

Post-calibration, the TCL P755 delivers a markedly improved colour performance for SDR content. The colour curves now align closely with ideal values, with a more consistent gamma stability across the range. While a slight drop at the beginning of the gamma curve persists, the accuracy in colour reproduction is significantly enhanced. The Colour Checker test reveals most colour samples are now under an error threshold of 2, showcasing much-improved colour fidelity with only minimal deviations, resulting in colours that feel notably more authentic to life.

HDR content benefits from these calibration adjustments as well. White balance corrections lend a more natural tone, with colours appearing more balanced overall. The EOTF curve, while nearer to the ideal reference line, still features a mild brightness elevation at the start, which can cause minor distortions in exceptionally bright scenes. However, overall tonal quality and detail resolution have both improved. Tone mapping also performs more effectively, enhancing detail in bright regions while maintaining better image accuracy.

In summary, while calibration does not bring flawless performance, it makes a substantial difference in the P755’s visual quality. Following these adjustments, the television provides a more accurate, realistic viewing experience in both SDR and HDR content, smoothing out many of the previous colour inconsistencies for a more visually engaging result.

Let's check how the A6N handles low-quality materials. When it comes to smoothing tonal transitions, the lack of posterization reduction or smoothing of tonal transitions in low-quality materials, such as television or DVD, may be noticeable for more demanding viewers. As for digital processing, the model was presented correctly, and the branches were free of characteristic jaggedness – the image is very plastic and soft, which may appeal to people who prefer this kind of image style.

The "Gradual Smoothing" function on the TCL P755 performs effectively, reducing visible boundaries between shades of the same colour and creating smoother tonal transitions. Unfortunately, this feature is unavailable in HDR mode, which can impact the quality of tonal gradations in high dynamic range content.

In terms of image scaling, the television shows some limitations. There are visible edge cut-offs, especially noticeable around figures and tree branches, which result in some detail blurring and a reduction in overall image sharpness. This is particularly noticeable when viewing lower-resolution content. Additionally, SD-quality images display a slight crop at the top and bottom, which may further impact viewing for standard-definition content.

The 60 Hz panel in the Hisense A6N will likely please those who enjoy watching movies, as the TV offers an "ultra motion smoother," allowing us to adjust the motion blur – either more choppy or smoother, theatrical. As for trailing, it performs quite average – noticeable trailing can be seen, especially on dark backgrounds, which is a rather typical feature in this tier of TVs.

The TCL P755 delivers satisfactory, though not flawless, motion smoothness. It includes a "Flicker Reduction" feature for films, allowing users to fine-tune motion smoothness on a scale from 1 to 10. This setting offers flexibility in tailoring the image to cinematic or more theatrical preferences, adjusting for a slower or faster appearance according to personal viewing taste.

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

The TCL P755 comes equipped with gamer-oriented features like ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gaming, and a Game Bar. ALLM automatically activates low latency mode to enhance response times and reduce input lag, while VRR syncs the screen refresh rate with the console's frame output, minimising screen tearing for a smoother gaming experience. Dolby Vision for gamers brings improved colour and contrast for compatible games, and the Game Bar allows easy access to essential settings like response time.

However, the 60 Hz panel limits the display to this refresh rate across resolutions, which may impact the fluidity in high-motion games. The absence of G-Sync also affects PC gamers, as gameplay on computers lacks this technology's extra smoothing. Notably, HGiG mode, meant to optimise HDR game visuals, is not fully functional on this model, which slightly detracts from the HDR gaming experience.
