TCL C655 Pro vs XIAOMI A PRO 2025

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. 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 for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

In the HDR category, the Xiaomi A Pro performs poorly overall. Under ideal conditions, it achieves a brightness level of around 250 nits, which is underwhelming. However, many competing models offer similar or even lower brightness levels. Such limited brightness is insufficient to fully showcase the potential of HDR content. In practical terms, the image lacks the depth and intensity expected from high-quality HDR. Instead, the visuals resemble standard dynamic range (SDR), with scenes that should display striking brightness and contrast appearing flat and uninspiring. That said, for its price, the television offers solid DCI-P3 colour gamut coverage at 92%, made possible by its quantum dot (QLED) technology. This ensures vibrant and saturated colours, making it an appealing choice for gamers and movie enthusiasts seeking richer hues and improved colour reproduction compared to standard models.

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with 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 excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

The Xiaomi A Pro 2025 performs best in movie mode for colour reproduction straight out of the box, though it is not without its flaws. An analysis of the white balance shows negative green values, causing distortions in white tones. At full white, there are noticeable deviations, and the high-contrast image leads to poor tonal transitions in red, negatively impacting the overall colour quality. Before calibration, the image often displays a pink hue in its scenery.

The gamma contrast graph falls below the 2.4 mark, indicating an overemphasis on darker tones and a lack of prominence in lighter areas. Additionally, the EOTF curve shows a sharp rise early on, which can result in lost detail in bright scenes and an oversaturated appearance. These issues suggest that further calibration is needed to balance the colour reproduction and enhance the overall image.

Factory colour settings on the Xiaomi A Pro 2025 are average, and while this is common in televisions of its class, users seeking accurate colour representation may need to adjust the settings. After proper calibration, the TV delivers a more natural and vibrant palette, aligning better with cinematic standards. For those prioritising precise colour reproduction, professional calibration will significantly improve image quality.

After calibrating the TCL 655 PRO television, a noticeable improvement in white balance can be observed, having completely eliminated the tendency for the screen to have an excessive pink hue, which was previously visible in factory mode. The image has taken on more natural tones, especially in white and bright elements, positively affecting the overall perception of the picture. As for brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image look washed out. Nevertheless, there are still some issues with the EOTF curve that are difficult to eliminate due to the design of the television and its limited number of dimming zones. These limitations prevent achieving ideal results in this regard. However, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high image quality and very good color reproduction.

After calibration, the Xiaomi A Pro 2025 TV shows significant improvement. The white balance is the most noticeable change, with previous errors corrected in HD and 4K content. Most deviations are now minimal, falling within an acceptable range, resulting in a more balanced and natural colour representation that enhances viewing comfort.

In terms of gamma, the drop has been largely addressed, leading to a more consistent rendering of tones across various scenes. However, the EOTF curve still hasn't seen substantial improvement, as there is limited control over dynamic tone mapping. This limitation means that some details may still be lost in bright scenes, affecting the perception of certain materials.

Despite these minor issues, the overall picture quality is improved after calibration. The enhanced white balance and reduced gamma issues provide a more realistic and enjoyable viewing experience. While further adjustments could enhance the image even more, the TV now showcases its potential, meeting the expectations of many users.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look 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 favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

The Xiaomi A Pro 2025 handles tonal transitions effectively, especially when dealing with lower-quality materials. Thanks to its advanced digital processing, the colour contour removal feature performs surprisingly well. Setting this option to "Medium" provides the best balance, enhancing the smoothness of tonal transitions while avoiding excessive smoothing of other image elements, like film grain.

In the case of a tested frame featuring a model with numerous branches in the background, the TV demonstrated its digital processing strengths. Adding artificial sharpness clarified the model’s details, particularly enhancing the hair's definition. However, around the branches, subtle contours emerged due to digital intervention. While this adds detail to the overall image, excessive sharpness can sometimes cause certain elements to appear unnaturally highlighted.

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

The Xiaomi A Pro 2025 features a motion smoothing option known as "Motion Smoothing," which is designed mainly for film viewing. It allows users to adjust the effect to either a more cinematic, film-like appearance with visible frames or a smoother, theatrical image. This feature will likely satisfy movie lovers. However, gamers and sports enthusiasts might be disappointed. The TV uses a 60 Hz refresh rate panel, typical for this price range, which doesn’t offer exceptional motion handling. Our "Ufo" test revealed some motion blur, so those seeking sharper moving images may find it lacking in this regard.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes 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 game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.

The Xiaomi A Pro 2025 includes several gamer-friendly features, such as the Game Bar, which sets itself apart from the typical dashboards seen in other brands. This feature allows quick access to game-related settings, making it convenient during intense gaming sessions. The TV also supports Automatic Low Latency Mode (ALLM), automatically switching to a game-optimised mode to reduce signal delays. However, it lacks HDMI 2.1 support, limiting compatibility with the latest gaming consoles that require higher bandwidth. Additionally, it does not support features like VRR (Variable Refresh Rate) or G-Sync, which are becoming essential for gamers seeking smoother visuals and reduced tearing. While the Xiaomi A Pro 2025 has some useful features, there are better options in this price range offering more advanced gaming solutions.
