TCL C655 Pro vs XIAOMI A PRO 2026

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.

If you are hoping for a cinema-grade HDR effect in the new Xiaomi A Pro 2026, you better cool your expectations quickly. This television is simply too dim to fully showcase the capabilities of contemporary films or series designed for the highest image quality. Our measurements showed brightness in the range of 200–300 nits, which is more akin to SDR content than ambitious HDR productions. In practice, this means that while most films may look fine, they certainly won't evoke that "wow" effect that other televisions are known for. Fortunately, not everything is lost – we must credit the PFS LED filter used here, which is a solution similar to the quantum dot technology found in QLEDs. Thanks to this, the coverage of the DCI-P3 colour palette reaches about 94%, resulting in vibrant, saturated colours in the vast majority of materials.

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.

What we saw in Filmmaker mode took us by surprise – and unfortunately not in a good way. The mode advertised as Hollywood standard resembled more of a shop window display. The white balance was shifted towards blue, leading to significant colour mistakes and burnt-out scenes in SDR content. It was slightly better, though still not perfect, in HDR materials. There were also issues there – the colour saturation and the entire palette consistently drifted towards cooler tones, resulting in an image that had more of an artificial, cold tint instead of a cinematic character. In other words: even in Filmmaker mode, which should showcase this television, we got an effect far from expectations.

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.

Although Xiaomi is not a brand associated with top-tier televisions, it must be acknowledged that even in a budget model like the A Pro 2026, the manufacturer left plenty of calibration settings. After a few adjustments, the SDR image gained a completely new look. Colours stopped drifting towards blue tones, whites took on a more natural quality, and most errors dropped to a practically invisible level. As a result, SDR content looked very good, surprisingly so for this price range.

It was somewhat different with HDR materials. Here, it was immediately evident what we had already mentioned – clipping in bright scenes and issues with balance control. Calibration helped only partly, as the limitations of the panel itself played a role. However, it must be emphasized that for SDR, the television had transformed beyond recognition and in a decidedly positive direction.

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.

Upscaling and digital image processing in the Xiaomi A Pro 2026 are not among the strengths of this model. One might expect that since the television was not designed to achieve record brightness levels, the manufacturer would focus on a more robust processor and a set of features that would "enhance" lower-quality images. Unfortunately – and here we are also faced with significant disappointment. On the positive side, we can note reasonably good upscaling, which handles HD materials and boosts them up to 4K in an acceptable manner. However, this is where the list of advantages ends. The television does not offer any features that improve tonal transitions or smooth out digital imperfections, so in most cases, we get a raw image, exactly as we deliver from an external source. On a large screen, such a lack of support makes lower-quality materials simply look bland. An additional problem is the phenomenon of overscan. When watching older materials, it happens that part of the image gets cut off, which only amplifies the impression that Xiaomi still has a lot of ground to make up in this category.

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.

The fluidity of motion in the Xiaomi A Pro 2026 is an interesting compromise that arises from the hybrid matrix used here. At its native 4K resolution, the maximum refresh rate is 60 Hz – sufficient for those who mainly watch films and series. It is precisely with them in mind that the manufacturer has added a motion smoother, allowing users to adjust the image to their own preferences – opting for greater fluidity or leaving more "cinematic" frames depending on the settings.

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.

Exactly – since Xiaomi has included the "Game Boost 120 Hz" feature, one might expect that they would follow up with a solid gaming package. Unfortunately, reality quickly dampens this enthusiasm. Aside from this mode (which, it must be admitted, is a great addition in a budget design), we only have a rather odd player panel. It's hard to call it a full-fledged "game bar" – it’s more of a simple overlay on the TV Menu with limited capabilities. And that would be about it. There’s a lack of ALLM, so the TV won’t automatically switch to game mode. There’s no VRR, so you can forget about smooth frame sync. We also won’t find support for Dolby Vision in games or the HGiG format, which are becoming increasingly standard on consoles. In short: besides the Game Boost 120 Hz, which actually allows for a more enjoyable experience at 1080p or 1440p, the Xiaomi A Pro 2026 offers nothing that could particularly attract gamers.
