Hisense A6N vs TCL C75B

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.

During our luminance test, the TCL C75B "spat out" about 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the television does not perform badly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half as low brightness values. However, for HDR enthusiasts seeking stronger light effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the 95% coverage of the DCI-P3 color palette. This is a very good result that easily suffices to enjoy a wide range of colors in content available on popular streaming platforms. Vivid and rich colors are definitely a strong point of this model.

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.

TCL C75B offers many picture modes, but in our opinion, the best choice is the "Film" mode. Although its settings are quite good, the television struggles with certain color reproduction issues. In tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered correct. This effect was particularly noticeable in skin tones, which appeared unnaturally warm. The main culprit of this phenomenon turned out to be the white balance, characterized by an excessive amount of blue and red in both HD and 4K HDR materials.

Another issue was the way brightness was reproduced. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, lost in total blackness (e.g., the bottom part of the screen in the comparative photo - the area around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that a similar problem may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and see how much could be extracted from this model after professional calibration. Details are described in the next section.

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.

After calibrating the TCL C75B, it has clearly improved in terms of color reproduction. Although the TV does not offer many options for adjusting the white balance, we were able to refine its settings significantly. As a result, the image has stopped being overly pink, and the colors now look much more natural and harmonious.

The gamma jump, which was previously a problem, has not disappeared completely, but we managed to significantly reduce it. This has made the details in dark scenes more visible – both in HD and 4K HDR material.

Unfortunately, the lack of local dimming is still noticeable. The "glowing black" effect remains, but that's a limitation of the display itself. Despite this, the colors after calibration look vastly better, and the image is much more enjoyable to watch.

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 TCL C75B has a tonal transition smoothing feature, but unfortunately, we can't praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature didn't work at all. It's hard to say something positive about it because, in practice, it seems completely useless.

The image scaling is better. The TV performs quite decently, although on thinner elements, like branches in the background, you can notice slight halos. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is the trimming of the image edges. In our tests, it happened that news tickers or other elements close to the edge of the screen were cut off. This is definitely something worth paying attention to, especially if we use the TV for watching news programs or content with text on the screen.

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.

TCL C75B definitely has something to offer gamers. The TV is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really great results, especially for a model from the budget range.

Additionally, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-step scale, providing a lot of customization options – everyone can set the smoothness to their liking.

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 C75B is undoubtedly a television designed for gamers. It offers almost everything that the most demanding console users need. With the implementation of full-bandwidth HDMI 2.1, the television supports features such as ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating across the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detail representation in HDR-optimized games. The C75B is also equipped with a very convenient interface for gamers in the form of a Game Bar, where you can check all key parameters, such as refresh rate, input lag, or picture settings – all within one click's reach.

In a nutshell: the C75B is an excellent choice for gamers, offering a wide range of features that allow for fully enjoying the capabilities of modern consoles and games.
