Hisense A6N vs TCL C655 / C69B (55"-85")

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.

Overall, the quality of HDR performance in TCL C655 / C69B looks quite promising. The average value in test patterns is around 450 nits, which already allows one to feel the effects of lighting and better image dynamics. However, as mentioned earlier, this effect may be partially suppressed by slight differences in bright and dark colors, resulting from the lack of local dimming technology. However, the DCI-P3 color gamut coverage of 94% deserves high praise, and this is made possible by the use of a quantum dot (QLED) panel. As a result, colors are vibrant and well-reproduced when watching HDR content.

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.

The TCL C655 / C69B television offers a movie mode that has been tested for color reproduction quality. Although this mode is called movie mode, unfortunately, it has quite a few errors that a director would certainly not want to see while recording their work. Starting with image analysis, it's worth looking at the white balance - both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red color dominates, making the colors too warm, and overall it has a pink or yellow tint. This can be seen in the picture below from the movie "Star Wars." The Colour Checker test confirms these errors - the color samples stray into inappropriate shades, affecting the overall color fidelity. A minor issue is the brightness characteristic. However, it is also not free of flaws. The gamma chart shows a strong spike at the beginning, causing the image to be overly bright, and the EOTF curve responsible for brightness in 4K HDR material shows significant fluctuations as well – it is visible how the television tries to maintain proper brightness, but it does not always succeed effectively.

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.

After calibrating the movie mode of the TCL C655 / C69B television, the white balance has been equalized, and the colors look as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really accurate, which means the television should not have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still visible, which is a natural phenomenon in televisions that do not have local dimming – they simply struggle to “shine” more brightly in a given part of the screen. Despite this structural limitation that cannot be overcome, we recommend adjustments in the settings, as the overall color representation looks really very good.

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 TCL C655 / C69B television handles tonal transitions in low-quality materials pretty well. The "Gradual Smoothing" feature at a low setting effectively smooths tonal transitions, but at the same time, it blurs important details, such as the texture of objects. On the positive side, it does not negatively affect film grain, allowing for a natural look of the image. As for digital processing, the television adds artificial sharpness, which may appeal to some users who prefer a sharpened image. However, for those who prefer a softer look, this may be a disadvantage. A downside is also that the image has been quite heavily cropped by so-called overscan, which reduces the field of view and cuts off the edges of the image.

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 C655 / C69B TV is equipped with a 4K@60 Hz panel, which means it performs best when watching movies and less dynamic content. It also has a "Flicker Reduction" feature that allows for adjusting the fluidity of the image – users can choose whether they prefer smoother motion or a more cinematic, frame-by-frame effect. The TV can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will definitely please gamers by offering a smoother image at the cost of resolution. It is worth noting that this feature is available in sizes from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

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 television TCL C655 / C69B offers an almost perfect set of features for gamers, supporting all the most important technologies. It has an ALLM feature that automatically switches the television to low latency mode, significantly improving responsiveness and minimizing signal delays, which is particularly important during dynamic gameplay. The VRR feature allows for synchronizing the screen refresh rate with the number of frames generated by the console, eliminating the tearing effect and ensuring smoother gameplay.

The television also supports Dolby Vision in game mode, providing better color reproduction and contrast in games that support this format, and the Game Bar enables quick access to gameplay-related settings such as response time, delay level, and other parameters. Unfortunately, C655 / C69B does not support 4K resolution at 120 Hz (with the exception of the 98" variant), which may be disappointing for more demanding gamers who expect the highest fluidity in high-resolution games. However, if we are willing to forgo 4K, the television offers support for Full HD and 2K at 120 Hz, providing a smoother image and being a great alternative for those who prefer a higher refresh rate at the expense of resolution.
