TCL C6K vs XIAOMI A PRO 2026

TCL C6K is a moderately bright TV that can showcase its full potential under the best cinematic conditions – the maximum brightness is around 600 nits. In scenes with large, intense light sources, the HDR effect can be really satisfying, providing a sense of cinematic brilliance. However, it should be noted that when managing the backlighting zones, there are situations where some elements become dimmed and sometimes can even become barely visible. It is clear that there is a lack of proper algorithm optimization here, although looking at the technical parameters in this price range, the design itself performs very well.

If you are hoping for a cinematic HDR effect in the new Xiaomi A Pro 2026, you better quickly cool your expectations. This TV is simply too dark to fully convey the capabilities of contemporary movies or series prepared for the highest quality picture. Our measurements showed brightness in the range of 200-300 nits, which are values that suit SDR content more than ambitious HDR productions. In practice, this means that most movies look okay, but they definitely won’t give you the "wow" effect that other TVs deliver. Fortunately, not everything is lost – a plus here is the use of the PFS LED filter, which is a solution similar to the quantum dot known from QLEDs. Thanks to this, the coverage of the DCI-P3 color gamut reaches about 94%, resulting in vibrant, saturated colors in the vast majority of materials.

This year's TCL televisions feature a Filmmaker mode, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for everyday watching of movies and series. Unfortunately, as is often the case, the best doesn't mean perfect. In the case of SDR content, the image was too warm because the red was strongly emphasized in the white balance. On the other hand, with HDR content, we had the opposite impression – the image became cooler than it should have been due to excess blue. Additionally, the brightness characteristic sometimes led to highlights being blown out. In practice, this resulted in quite noticeable color test inaccuracies that are hard to accept in a mode advertised as "by the creators."

What we saw in Filmmaker mode surprised us greatly – and unfortunately not in a good way. The mode advertised as Hollywood standard resembled more of a display in a store window. The white balance was shifted towards blue, leading to huge color errors and the effect of washed-out scenes in SDR content. It was a little better, though far from perfect, in HDR materials. There, problems were also visible – color saturation and the entire palette consistently shifted towards cooler tones, which made the image appear more artificial and cold rather than cinematic. In other words: even in Filmmaker mode, which should be the showcase of this television, we got a result far from expectations.

Thanks to the white balance correction, it was possible to significantly reduce the C6K's tendency to distort colors, which resulted in a very good final outcome. After calibration, we will no longer observe the effect of excessive warming of scenes in SDR or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, there are few complaints – the image looks really good, especially in older movies, TV shows, or materials from YouTube. This is much worse for HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the construction become apparent. The TV tends to overly brighten the smallest parts of the frame, and in other situations, it can dim the entire scene too much. The effect of calibration is therefore evident, and in terms of color, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, its management by the C6K simply cannot be overcome.

Even though Xiaomi is not a brand associated with top-of-the-line televisions, it must be acknowledged that even in a budget model like the A Pro 2026, the manufacturer left quite a few calibration settings. After a few adjustments, the SDR picture gained a completely new character. The colors stopped veering into blue tones, the whites became more natural, 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 material. Here, it was immediately noticeable what we had already mentioned - the overexposure of bright scenes and issues with balance control. Calibration only helped partially because the limitations of the panel itself played a role. However, it should be emphasized that in the case of SDR, the television transformed beyond recognition, and in a decidedly positive direction.

The TCL C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the lack of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – content of very low quality will not gain new life here, as the image processor has its limitations. On thin lines or details, the characteristic tearing is visible, which reveals the absence of advanced image enhancement algorithms. It is also a pity that the C6K lacks the feature for smoothing tonal transitions – in older films or video materials, color banding can be noticeable and may be bothersome during long viewing sessions.

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 TV wasn’t designed to achieve record brightness levels, the manufacturer would have opted for a more robust processor and a set of features that would "enhance" lower quality images. Unfortunately – we were also quite disappointed here. On the plus side, there is reasonably decent upscaling that handles HD materials and elevates them to 4K in an acceptable manner. However, this is where the list of advantages ends. The TV does not offer any features to 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, this lack of support makes lower quality materials look simply bland. An additional problem is the phenomenon of overscan. When watching older materials, it sometimes happens that part of the image is cut off, which only intensifies the impression that Xiaomi still has a lot to catch up on in this category.

TCL C6K features a 144 Hz panel, which is a significant advantage in this price range. This is an important step forward compared to the previous model C655 PRO, which offered only 60 Hz at 4K. The difference is especially noticeable when watching sports or playing games – the ball, athletes, or fast action in a game are displayed more clearly and without losing details. An interesting fact is also the ability of the panel to operate at 240 Hz, which the manufacturer does not mention in official materials. We will return to this topic when discussing the game mode for PC.

TCL also added a feature for movie watchers: "Motion Clarity," which allows you to adjust the image to your preferences using two simple sliders. You can keep the movie frame visible or opt for a very smooth, almost theatrical effect. This way, everyone can find settings tailored to their taste.

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

The TCL C6K is a TV that can confidently be called equipment designed for gamers. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there's a practical Game Bar, a panel with the most important settings readily available – useful when we want to quickly change something during gameplay (e.g., screen aspect ratio: Yes, that’s possible!). The wide VRR range, reaching up to 240 Hz, deserves attention. However, this is mainly an option for PC gamers who drop below the native 4K resolution. Then the TV can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still quite broad. The only drawback is a slight ghosting that can sometimes be seen in dynamic scenes. Other than that, the C6K offers everything gamers expect from a TV.

Indeed – since Xiaomi has added the "Game Boost 120 Hz" feature here, one might expect that they would follow up with a solid gaming package. Unfortunately, reality quickly dampens that enthusiasm. Aside from this mode (which, it must be said, is a great addition in a budget build), we have just a rather bizarre player panel. It's hard to call it a fully-fledged "game bar" – it's more of a simple overlay on the TV Menu with limited options. And that would be about it. There is no ALLM, so the TV won't automatically switch to game mode. There is no VRR, so you can forget about smooth frame synchronization. We also won't find support for Dolby Vision in games or the HGiG format, which are becoming increasingly standard on consoles. In short: apart from Game Boost 120 Hz, which does indeed make playing more enjoyable in 1080p or 1440p, the Xiaomi A Pro 2026 offers nothing particularly appealing to gamers.
