Hisense A6N vs TCL C655 Pro

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.

In the HDR effect quality category, the television TCL 655 PRO demonstrates decent capabilities, achieving a peak brightness of 550 nits. This allows for enjoyment of the HDR effects, which is particularly evident in scenes such as the first from the film Life of Pi or the last frame from The Meg. Nevertheless, the limited number of dimming zones causes some issues. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims to achieve deep blacks, but at the cost of brightness – resulting in a drop in brightness of even half during those moments. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles more of an SDR. Regardless, the colour gamut coverage deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

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.

Each of our television tests is conducted in film mode, which usually offers the best colour reproduction. Nonetheless, even this mode is not free from issues, as we noted in the model TCL 655 PRO.

In the case of HD content, the white balance distinctly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation is better, but there is a noticeable tendency to excessively emphasise the colour blue. As a result, the picture may appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristics also leave much to be desired. The Gamma graph indicates serious difficulties with excessive brightening, causing the overall presentation to appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we detailed in the paragraph concerning HDR effects.

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 calibrating the television TCL 655 PRO, a noticeable improvement in white balance is evident, where the tendency for the screen to have an excessive pink hue has been completely eliminated, which was previously visible in the factory mode. The image has taken on more natural tones, especially in white and light elements, positively affecting the overall perception of the picture. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer overly bright, which previously made the image appear washed out. However, there are still some issues with the EOTF curve, which are difficult to eliminate due to the design of the television and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. Nevertheless, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

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 TCL 655 PRO television performs quite well with tonal transitions in lower quality materials. The "Gradual Smoothing" function at a low setting effectively smooths out tonal transitions, but this comes at the expense of losing some important details, such as the texture of objects. One positive aspect is that it does not negatively affect film grain, which helps maintain the natural appearance of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who like a softer, subtler look may find this a drawback. Additionally, a downside is the cropping of the image due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

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 TCL C655 PRO television is equipped with a 4K panel with a refresh rate of 60 Hz, making it best suited for watching films. Additionally, the "Flicker Reduction" feature allows users to adjust the smoothness of the image, giving them the choice between a smoother motion and a cinematic, frame-by-frame effect. Moreover, the television performs well with lower resolution materials, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy a smoother picture at the expense of lower resolution.

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 TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all the key technologies that significantly enhance the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in improved responsiveness and minimal signal delay – particularly important in dynamic titles. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in gaming mode allows for more detailed colour and contrast reproduction in games that support this format, while the Game Bar provides quick access to essential settings such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz delivers exceptionally smooth visuals, presenting an attractive alternative for enthusiasts of higher refresh rates.
