Hisense A6N vs TCL C655 Pro

The quality of HDR effect on the A6N unfortunately does not impress. A peak brightness of 250 nits does not allow for spectacular effects, and HDR appears rather dull, resembling more of a standard SDR. This situation will not satisfy more demanding users who want to enjoy high-quality film materials. Additionally, the colour gamut coverage is also not very impressive – DCI-P3 at 82% is an average result that does not allow for full enjoyment of vibrant colours in HDR materials.

In the HDR effect quality category, the television TCL 655 PRO shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoying HDR effects, which can be clearly seen in scenes such as the first one from the movie Life of Pi or the final shot from The Meg. However, 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 more. The dimming algorithm aims for deep blacks, but at the cost of brightness – which at those moments can cause a drop in brightness of even half. In these more challenging scenes with small elements, it's hard to find any praise, and the HDR effect resembles SDR. Nevertheless, the coverage of the colour palette deserves recognition, 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 a lot 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. Particularly noticeable is the problem with white balance, for both HD and 4K material, which is heavily skewed by the dominance of blue hues. This results in artificial, cold tones, which is clearly visible in the comparative image 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 with maintaining a level of 2.4 – the graph is significantly below the reference value, leading to excessive brightness of the image and washed-out blacks. The EOTF curve for 4K materials also indicates brightness issues – at the beginning, there is a notable spike, which results from the television's excessive brightness, negatively affecting image quality. Such an image characteristic does not allow for full enjoyment while watching films and requires manual adjustment.

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

In the case of HD content, the white balance clearly 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 looks better, but there is a tendency to overly emphasise the colour blue. As a result, the image can give a sense of artificial sharpness, which proves to be uncomfortable for the eyes over a longer period. The brightness characteristics also leave much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, making the overall presentation appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we have detailed in the paragraph regarding HDR effects.

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

Let's check how 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 is presented correctly, and the branches lack characteristic jaggedness – the image is strongly plastic and soft, which may appeal to those who prefer this kind of image style.

The TCL 655 PRO television handles tonal transitions quite well in lower-quality material. The "Gradual Smoothing" feature at low settings effectively smooths tonal transitions, but this comes at the cost of losing some essential details, such as the texture of objects. On the plus side, it doesn't negatively affect film grain, which helps maintain a natural look to the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a bolder image. However, individuals who favour a softer, more subtle look may find this a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and cuts off 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 satisfy those who enjoy watching movies, as the TV offers an "ultra motion smoother," allowing us to adjust the smoothness of the image – either more choppy or more fluid and cinematic. When it comes to motion blur, it performs rather average – noticeable blur is present, especially on dark backgrounds, which is quite typical for this range of TVs.

The TCL C655 PRO television is equipped with a 4K display with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows for adjusting the smoothness of the picture, giving the user the choice between smoother motion and a cinematic, frame-by-frame effect. Furthermore, the television performs well with lower resolution content, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will surely appeal to gamers who can enjoy a smoother image, albeit at the cost of lower resolution.

Hisense A6N is a television that is likely to appeal to occasional gamers, mainly 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 TV supports features such as ALLM (automatic low latency mode), VRR (variable refresh rate), and Dolby Vision, allowing for better picture quality and motion smoothness in games that support these technologies. Furthermore, the low input lag ensures quick reactions in games, which is crucial, especially in dynamic productions. With these features, although the TV is not the ideal choice for demanding gamers, it provides solid support for those who appreciate comfortable gaming without complicated settings. It's a perfect solution for individuals who want to enjoy gaming without high hardware requirements while still accessing modern technologies that enhance gameplay.

The TCL C655 PRO TV offers an almost perfect set of features for gamers, supporting all key technologies that significantly enhance gameplay comfort. The ALLM feature automatically switches the TV to low-latency mode, improving responsiveness and minimising signal delay – particularly important in fast-paced titles. VRR synchronises the screen refresh rate with the frame rate generated by the console, eliminating screen tearing and ensuring smoother gameplay.

Support for Dolby Vision in game mode enables more detailed colour and contrast representation 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 offers exceptionally smooth visuals, making it an attractive alternative for high refresh rate enthusiasts.
