TCL C6K vs XIAOMI A PRO 2026

TCL C6K is a moderately bright television 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 truly satisfying, providing a sense of cinematic sparkle. However, it is important to remember that when managing backlight zones, there are occasions where some elements are dimmed, and at times become barely visible. It is clear that there is a lack of proper algorithm optimisation here, although looking at the technical parameters in this price range, the overall construction performs exceedingly well.

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.

In this year's TCL televisions, the Filmmaker mode has appeared, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for daily watching of films and series. Unfortunately, as is often the case, the best does not mean perfect. In the case of SDR content, the image was too warm, as the red was quite pronounced in the white balance. Conversely, with HDR content, we had the opposite impression – the image became cooler than it should have been due to an excess of blue. Additionally, the brightness characteristics sometimes led to overexposure. In practice, this resulted in quite noticeable errors in colour tests, which are difficult to accept in a mode advertised as "from the creators."

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.

Thanks to the white balance adjustment, it was possible to significantly reduce the C6K's tendency to distort colours, which translated into a very good final result. After calibration, we will no longer observe the effect of excessive warmth in SDR scenes or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, it is difficult to have major objections – the image looks really good, especially in older films, television programmes, or materials from YouTube. It fares much worse in the case of HDR content. An analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the design become apparent. The television tends to over-brighten the smallest parts of the frame, and in other situations, it can dim an entire scene too much. The effect of calibration is therefore evident, and in terms of colour, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, from its management by the C6K simply cannot be overcome.

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.

TCL C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the absence of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – very low-quality content will not gain a new life here, as the image processor has its limitations. On thin lines or details, there is a noticeable characteristic jerking, which reveals the lack 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, colour banding can be noticeable and can be distracting during longer 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 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 C6K utilises a 144 Hz panel, which is a significant advantage in this price range. This is an important step forward compared to the previous model, the C655 PRO, which only offered 60 Hz in 4K. The difference is especially noticeable when watching sports or gaming – the ball, players, or fast action in a game are shown more clearly and without losing details. Interestingly, the panel can also operate at 240 Hz, which the manufacturer does not mention in the official materials. We will return to this topic when discussing the PC gaming mode.

TCL has also added a feature for those watching films: "Motion Clarity", which allows users to adjust the image to their liking using two simple sliders. One can either keep the film frame visible or opt for a very smooth, almost theatrical effect. This way, everyone can find settings tailored to their taste.

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 C6K is a television that can confidently be described as equipment designed with gamers in mind. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there is a practical Game Bar, which is a panel with the most important settings easily accessible – useful when we want to quickly change something during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR is also noteworthy, reaching up to 240 Hz. However, this option is primarily for PC gamers who will drop the resolution below native 4K. At that point, the television can spread its wings and demonstrate extra fluidity, especially in fast-paced esports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still really broad. The only drawback might be slight ghosting, which can sometimes be seen in dynamic scenes. Apart from that, though, the C6K offers everything that gamers expect from a television.

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.
