TCL C655 / C69B (43" - 50") vs XIAOMI A PRO 2025

The quality of the HDR effect in the TCL C69B / C655 television is quite average. With a brightness level of 350 nits, although not the worst, it still doesn't allow for a full enjoyment of HDR effects, which require higher luminance to showcase their power. Additionally, despite the application of a quantum dot coating (QLED), the television offers an average coverage of the wide DCI-P3 colour gamut at 91%, which may limit its richness of colours in HDR content.

In the HDR category, the television Xiaomi A Pro is, to put it plainly, lacking. Under ideal conditions, it offers brightness at around 250 nits. This is a poor result; however, in this price range, many competing models offer similar or lower values. Such brightness is too low to fully realise the potential of HDR content. In practice, this means that the image does not gain the appropriate depth and intensity expected from high-quality HDR. These values are more characteristic of standard dynamic range (SDR), which means that the true HDR effect remains beyond the reach of this model, and scenes that should stand out with spectacular brightness and contrast seem flat and lacklustre. However, for its price, the television offers good coverage of the DCI-P3 colour gamut at 92%, thanks to the use of quantum dot technology (specifically PFS LED). This results in vibrant and saturated colours, which will appeal particularly to gamers and film enthusiasts who appreciate richer shades and better colour reproduction compared to traditional televisions without this technology.

The television TCL C69B / C655, tested in movie mode, unfortunately does not meet expectations in terms of colour accuracy. Although movie mode suggests better representation, it has almost nothing in common with film. There are many errors evident, particularly in white balance – for both HD and 4K HDR content – where the dominance of the blue colour is very noticeable. For the viewer, this means that the image becomes unnaturally cool, affecting the overall perception of colours and the visual impression. The colour checker confirms these errors, showing that colours shift towards cooler shades.

As for brightness characteristics and the related contrast, gamma is very unstable for the material, which can make the image slightly darker. The EOTF curve for the 4K material shows some errors, with significant deviations towards the end of the graph, which negatively impacts the reception of darker parts of the image.

The Xiaomi A Pro 2025 television has been tested in movie mode, which offers the best colour reproduction straight out of the box. However, it is worth noting that it is not free from flaws. Analysing the white balance, it can be observed that the values for green are in the negative. This phenomenon leads to some distortions in the shades of white, and with pure white, the graph shows clear deviations. The over-contrasted image results in inappropriate tonal transitions in red, negatively affecting the quality of colour display. Generally, in the image below, it can be seen that the overall scenery before calibration acquires pink hues. Additionally, when analysing gamma contrast, the graph is significantly below the 2.4 value, suggesting that the television overly emphasises dark tones, and the brighter areas of the image may be less vivid. Furthermore, the EOTF curve shows a strong peak at the beginning, which can lead to a loss of detail in bright scenes and an unpleasant feeling of over-drawing. These aspects indicate a need for further calibration to achieve a more balanced colour reproduction and improve the overall image quality. Users who expect precise colour reproduction may be forced to take measures to adjust the television settings to achieve more realistic and natural visual results. In the xiaomi tv a pro 2025, the factory colour settings in Xiaomi are average and may require calibration. After proper colour adjustment, the image gains a natural and vibrant colour palette, much closer to cinematic standards. It is worth adding that the issue of inaccurate colour reproduction is typical for many televisions in this class, meaning it is not a flaw unique to the Xiaomi A Pro 2025 TV. For those who value perfect colour reproduction, professional calibration will prove to be a key element that enhances the overall image quality.

After calibration, the movie mode on the TCL C69B / C655 television improves in quality. The greatest improvement can be seen in tonal quality, and the white balance presents itself much better – with no major errors. We will no longer see an excessive dominance of cool tones. Gamma has also been improved, leading to a more stable representation of brightness and contrast. However, due to limitations in the form of the television's average colour palette, Colour Checker tests for 4K materials did not achieve remarkable results. Despite these technological limitations, the image has become more authentic, positively affecting the reception of film content.

Now it's time to check how the Xiaomi A Pro 2025 television has performed after calibration. The biggest beneficiary of this process is the white balance. After the calibration was conducted, all previous errors were corrected in both HD and 4K content, and most errors no longer fall significantly outside the value of "2". This means a much more balanced and natural colour representation, which certainly affects the viewing comfort. In terms of gamma, the drop was significantly reduced, resulting in a more consistent tonal representation across various scenes. Nevertheless, the EOTF curve has not been significantly improved due to a lack of effective control over dynamic tone mapping. This limitation means that there are still some issues with detail reproduction in bright scenes, which may affect the perception of certain materials. However, despite these minor shortcomings, the overall shape of the image is definitely better after calibration. The television has gained in quality, and the improved white balance along with reduced gamma issues allows users to enjoy a more realistic and pleasant visual experience. Further adjustment of settings may enhance image quality even more, but even now the television demonstrates its capabilities, meeting the expectations of many users.

The "Gradual Smoothing" function works very well on the TCL C69B television and, surprisingly, does not remove desirable effects such as film grain – unlike some solutions from other manufacturers. When it comes to image scaling, unfortunately, it looks poor. The television artificially sharpens the image, causing the edges of objects to be quite jagged. This state of affairs may appeal to some users who prefer a more "hard" look to the image, but it is not an ideal solution for those who value naturalness and fluidity of details.

How does the Xiaomi A Pro 2025 television cope with tonal transitions, especially with lower-quality materials? Thanks to advanced digital processing, the colour contour removal function works surprisingly well. We recommend setting this option to "Medium" – the television significantly improves the fluidity of tonal transitions while avoiding excessive smoothing of other image elements, such as film grain.

In the case of the tested image featuring a model and numerous branches in the background, the Xiaomi A Pro 2025 showcased its capabilities in terms of digital processing. Adding artificial sharpness to this scene made the details of the model more pronounced, and her hair appeared more detailed. However, delicate contours appeared around the branches in the background, which were a result of digital interference. Although this enhances the overall impression of detail, excessive sharpness can make some elements of the image seem unnaturally emphasised.

The TCL C69B / C655 television in its smallest variants offers decent, though not perfect, results in terms of motion smoothness. For films, the television features a "Flicker Reduction" function that allows adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the appearance of the image to our cinematic or more theatrical preferences (with either lower or higher speed).

Xiaomi A Pro 2025 offers a motion smoothing feature called "Motion Smoothing," which primarily works in films. It can be adjusted to prefer either a more cinematic, film-like effect with visible frames, or a smoother, theatre-like image. This function should satisfy those who intend to watch mainly films on it. However, gamers and sports fans may feel disappointed. The 60 Hz refresh rate panel, typical in this price range, does not impress. Our "Ufo" test revealed some motion blur. Those expecting better sharpness of moving objects may be slightly let down.

The TCL C69B / C655 television in its smallest variants offers a range of features dedicated to gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, improving responsiveness and minimising delays in control. VRR allows the screen refresh rate to synchronise with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay. Dolby Vision for gamers ensures better colour and contrast reproduction in games that support this format, resulting in enhanced picture quality. Meanwhile, Game Bar provides quick access to game settings and monitors key parameters such as input lag.

However, the television has certain limitations that may affect gaming comfort. The 60 Hz panel does not allow for displaying signals with higher refresh rates, which may impact the smoothness of the image in fast-paced games. The lack of support for G-Sync technology for PCs may also be noticeable when gaming on a computer, especially in demanding, fast-paced titles.

Xiaomi A Pro 2025 offers several features useful for gamers, including Game Bar, which is different from the typical "dashboards" with interfaces found in other manufacturers' products. Thanks to this, users can quickly access game-related settings, which is convenient during intense sessions. The TV also supports Automatic Low Latency Mode (ALLM), meaning it automatically switches to a mode optimised for gaming, reducing signal latency. Unfortunately, it lacks support for HDMI 2.1, limiting its capabilities for connecting the latest gaming consoles that may require higher bandwidth. Additionally, the TV does not support features such as VRR (Variable Refresh Rate) or G-Sync, which are increasingly desired by gamers, as they allow for smoother visuals and eliminate tearing. For these reasons, although Xiaomi A Pro 2025 has some features for gamers, in this price range, better options can be found that offer more advanced solutions dedicated to gamers.
