Hisense A6N vs TCL P755

Unfortunately, the HDR effect quality on A6N is not impressive. A peak brightness of 250 nits doesn’t allow for spectacular highlights, and HDR looks rather muted, more like ordinary SDR. This will not satisfy more demanding users who want to enjoy high-quality movie content. Additionally, the color gamut coverage is not very impressive either: DCI-P3 at 82% is an average result that doesn’t let you fully enjoy vivid colors in HDR material.

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 color reproduction category, the Hisense A6N in Filmmaker Mode leaves much to be desired. Although the mode's name suggests we should expect faithful movie color reproduction, the reality is different. The TV has significant picture quality problems. The white balance issue is particularly noticeable for both HD and 4K material, as it is heavily skewed by a dominance of blue. This results in artificial, cool tones, clearly visible in the comparison photo below. The ColorChecker test further confirms these errors, which are compounded by low color gamut coverage.

The gamma luminance curve shows a serious problem maintaining the 2.4 level, with the plot well below the reference value. That leads to excessive image brightening and washed-out blacks. The EOTF curve for 4K material also indicates brightness problems. At the low end there is a pronounced bump caused by the TV's excessive brightening, which negatively affects picture quality. This image behavior prevents fully enjoying movies and requires manual correction.

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 in its settings options and tools to adjust many picture parameters, which we used. As for the white balance, we managed to remove the excess blue; this is clearly visible in the comparison photo below, where the boy in the image practically "comes to life". A large improvement can also be seen in the gamma brightness response, as the TV no longer has serious issues with overbrightening the entire picture. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to this model's exceptionally low brightness. For HDR content we use dynamic tone mapping, which allows recovery of many details despite lifting the midtones. For this TV that brings more benefits than drawbacks. The errors that remain visible in the color gamut test and the ColorChecker for 4K content stem from the low color gamut coverage and are difficult to eliminate because of the TV's characteristics. Even so, the image tonality is much better, so we recommend calibrating the factory settings, which 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 see how A6N handles low-quality material. When it comes to smoothing tonal transitions, the lack of a function to reduce posterization or smooth tonal transitions in low-quality sources, such as broadcast TV or DVD, may be noticeable to more demanding viewers. As for digital processing, the model was rendered correctly and the branches were free of the typical jagged edges. The image has a pronounced sense of plasticity and is soft, which may appeal to those who prefer that kind of picture 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 Hisense A6N will likely please people who enjoy watching movies, because the TV offers an "ultra motion smoothing" feature that lets you adjust the image's motion, making it choppier or smoother and more cinematic. As for motion blur, it is rather average. You can see quite noticeable blur, especially on dark backgrounds, which is a common trait in this class 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.

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 players. Still, it offers several features that can make gaming more enjoyable. The TV supports functions such as ALLM (automatic low-latency mode), VRR (variable refresh rate) and Dolby Vision, which let you enjoy better picture quality and smoother motion in games that support those technologies. Moreover, the low input lag means in-game reactions are fast, which is crucial, especially in fast-paced titles. Thanks to these features, although the TV isn’t the ideal choice for demanding gamers, it provides solid support for those who value comfortable gaming without complicated settings. It’s an ideal solution for people who want to enjoy gaming without high hardware demands while still having access to modern technologies that enhance gameplay quality.

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.
