Compare: TCL C855 vs XIAOMI A PRO 2025

Once again, the manufacturer shows that despite being a relatively young player in Poland (but not globally) when it comes to the RTV market, it certainly cannot be said that it is a second-rate choice. The TCL C855 is an incredibly versatile device that performs well in various applications and excels in its price range. Thanks to Mini LED backlighting, the results for contrast and black levels are very solid, allowing for a deep and vivid image. It is worth noting that the television's algorithm effectively manages to maintain uniformity of blacks, and the blooming effect is rarely noticeable. This backlighting is also a strong point for the television in HDR content, although with some reservations. The TCL C855 can achieve brightness levels of up to 1800 nits, which is an impressive result; however, brightness can drastically drop, even to around 200 nits, when a bright but small element appears on the screen. Another drawback is the boosted mid-tones, which can lead to a loss of contrast and reduce the image's alignment with the director's vision. The television also performs excellently when connected to a console or a powerful PC. In this category, the TCL C855 truly shows its strength, offering extremely low latency and high-quality gameplay, thanks to the full implementation of HDMI 2.1 features. The Google TV operating system is another advantage, providing the user with nearly unlimited possibilities for installing applications, even those outside the official store, thanks to support for APK files.

In summary, the TCL C855 is the ideal choice for those who know what they expect from a television. It is a good, versatile piece of equipment that, although not perfect, offers great picture quality, low gaming latency, as well as a flexible and expanded operating system.

Xiaomi A Pro 2025 is an affordable QLED model that works well as a basic television at home. The Google TV operating system deserves special mention. Thanks to it, you can easily use apps like Netflix or YouTube. The interface is clear and easy to navigate, and the voice search capability in Polish ensures that we can quickly find the content we are interested in. The picture quality of the A Pro 2025 is sufficient for everyday TV watching or movies. Smooth tonal transitions and the enhancement of older materials make even lower resolution content look good. However, the screen brightness may disappoint in very sunny rooms – here, the TV performs moderately, but it fares much better in a darkened room. The television is more suited to occasional gaming. The low input lag provides quick response times, which is important for dynamic games. However, the 60 Hz panel and lack of more advanced features may not appeal to gamers looking for perfect image fluidity. On the other hand, A Pro 2025 may be sufficient for those who play from time to time. Not everything works perfectly. When connecting the TV to a computer, the fonts are hard to read, which can be an issue when working with text. The Google TV system itself can be a bit slow, which sometimes makes it difficult to switch between apps quickly. Xiaomi A Pro 2025 is a simple and functional TV that is good for everyday TV watching and using apps. It has its drawbacks, such as average brightness and issues with font readability, but at this price, it offers a lot. It’s a good choice for those looking for budget equipment for basic uses.

TCL C855 uses a high-contrast VA panel. The ANSI contrast (without dimming) reached a very respectable 5238:1, which allows for at least very good black levels. Additionally, the panel is equipped with multi-zone Mini LED backlighting, which is divided into 1344 independent dimming zones for the 65-inch model. This number allows for very good results in our tests. It is worth noting that TCL, as one of the few manufacturers, offers such a panel specification without spending excessively, unlike the classic big four manufacturers. As you can see, in the vast majority of scenes we've prepared, the results are impressive, particularly in the first three scenes, as even in the third, with a result of 54,000:1, it cannot be said that the black levels and contrast are weak, as they are more than satisfactory. These worsen in two scenarios: scenes with film strips and when there are many elements surrounded by black on the screen. And just as the last of the test scenes still has excellent contrast, in the final tested scenario, a slight blooming of blacks can be noticed. The frame from the film "Oblivion" performed excellently on TCL C855, and the level of black can even be compared to OLED screens, which is no small feat. It is also worth noting the good separation of lights, which is not an easy thing to achieve. Our flagship scene from "Sicario 2" also performed well in terms of contrast, but it is evident that details are lost in the blacks on the first, second, and third planes. The operation of the backlight control algorithm, which minimizes halo/blooming effects to an absolute minimum, deserves praise as well. However, it is worth noting that very small elements, such as stars, can sometimes be completely dimmed by the TCL C855.

Xiaomi A Pro is equipped with a VA panel, which inherently offers distinctly better black depth and colour intensity compared to IPS panels, especially in darker conditions. Based on the tests conducted, the contrast measurement tool indicated a maximum value of around 6000:1. This is a solid result, ensuring good separation of image elements in darker scenes. An example is the film Oblivion, where the TV excelled at separating bright and dark areas, enhancing the visual effects. Unfortunately, the TV does not support local dimming technology, which is an obvious fact in this price range. This particularly stands out in tougher scenes, such as those from the film Sicario 2. In such moments, the black loses intensity and starts to resemble a navy blue shade. The lack of dynamic dimming of image segments means that details that should be deeply dimmed remain slightly illuminated.

TCL C855 delivers a highly varied HDR effect. On one hand, the television truly shines, while on the other, it resembles a lower model with FALD backlighting. Such a state of affairs is regularly observed with this brand, so it was not a surprise for us. The first and last scene, which has large light elements, looks phenomenal, "shining" with brightness levels of 1470 and 1820 nits respectively. Such effects will certainly make many people squint, while simultaneously feeling the extraordinary dynamism of the scene itself. You can truly feel as if you were inside the movie. The situation drastically changes when small or minor elements with high luminance surrounded by black appear on the screen. The TCL C855, to avoid the halo effect, significantly reduces brightness to a level of even 240 nits, which is a disappointing outcome, causing the film to not look like it was shot in HDR. The HDR effect in TCL C855 makes watching dynamic scenes more engaging, and the viewer can feel like they are part of the action. Even with smaller elements of high luminance, the television manages to maintain details without excessive dimming. Moreover, the TCL C855 test shows that the brightness of the image is adapted to scenes with a large amount of detail, increasing viewing comfort.

In the HDR category, the television Xiaomi A Pro performs, to be blunt – poorly. In ideal conditions, it offers brightness at around 250 nits. This is a weak result; however, in this price range, many competing models offer similar or lower values. Such brightness is too low to fully capture the potential of HDR content. In practice, this means that the image lacks the proper depth and intensity expected from high-quality HDR. These values are more characteristic of Standard Dynamic Range (SDR), which means the true HDR effect remains out of reach for this model, and scenes that should stand out with spectacular brightness and contrast seem flat and lacking in vibrancy. However, for its price, the television offers good coverage of the DCI-P3 colour palette at 92%, thanks to quantum dot technology (specifically PFS LED). This results in vibrant and saturated colours, which will appeal particularly to gamers and movie enthusiasts who appreciate richer hues and better colour reproduction compared to traditional televisions without this technology.

The best factory mode for the TCL C855 is "Film," and it is on this mode that we conducted all our tests. However, like every mode predefined by the manufacturer, it had flaws that are worth correcting to achieve an image that is as close as possible to what the film producer intended. We will look at the colour characteristics in both SDR and HDR materials. Taking the former into account, we see a clear dominance of green in the white balance, which, as you might guess, gave an unpleasant greenish tint to the entire image. Examining a very important gamma chart, responsible for the contrast of the image, we see a significant deviation from the reference line marked at 2.4. From the left, we can observe a strong spike in the measured value, which at this point caused contrast exaggeration and blending of details into a dark blob. This state of affairs persisted for quite a while, up to 20% of the chart’s value, before then diving below the reference. This, in turn, meant that the image was brightened and contrast decreased significantly. The factory mode performed somewhat better in HDR materials, as the white balance looked quite good, except for the second half, where green again took over. Looking at the EOTF curve, which, unlike gamma, shows the rate of brightness increase, we see primarily two errors: the darkest scenes were too dark, and the brightest ones were overexposed. This, by the way, could be observed in the scene from the film "Pan" in the check paragraph for the TV's HDR.

The Xiaomi A Pro 2025 TV has been tested in movie mode, which offers the best colour reproduction straight out of the box. However, it’s worth noting that it is not without flaws. Analysing the white balance, one can see that the green values are in the negative. This phenomenon leads to some distortions in the shades of white, and at full white, the graph shows clear deviations. The high-contrast image results in inadequate tonal transitions in red, which negatively affects the quality of colour display. Generally, in the image below, it can be seen that the entire scenery before calibration takes on pink hues. Additionally, when analysing the gamma contrast, the graph is significantly below the value of 2.4, suggesting that the TV overly emphasises dark tones, while the brighter areas of the image may appear less pronounced. Furthermore, the EOTF curve shows a strong spike at the start, which can lead to a loss of detail in bright scenes and an unpleasant feeling of over-exaggeration. These aspects indicate the need for further calibration to achieve a more balanced colour reproduction and improve overall picture quality. Users who expect precise colour reproduction may need to take action to adjust the TV settings to achieve more realistic and natural visual results. In xiaomi tv a pro 2025, the factory colour settings in Xiaomi are average and may require calibration. After appropriate colour adjustment, the image gains a natural and vibrant colour palette, significantly closer to cinematic standards. It’s worth adding that the issue of inaccurate colour reproduction is typical for many TVs of this class, meaning it’s not a fault unique to the Xiaomi A Pro 2025 TV. For those who value perfect colour reproduction, professional calibration will be a key element that enhances overall picture quality.

TCL, just like the vast majority of manufacturers, provides advanced calibration tools in its televisions. Here we find 2- and 20-point grey scale adjustments as well as an advanced colour management system. The results, as you can see, are very good and in SDR materials we have significantly approached the reference image. We eliminated both the green tint and the gamma issue, although there is still a slight "kink" at the very beginning. It went a bit worse with HDR materials, which the television ChooseTV C855 did not allow us to model properly. We only managed to slightly adjust the EOTF curve and significantly improve the colours themselves.

Now it’s time to check how the Xiaomi A Pro 2025 TV performed after calibration. The biggest beneficiary of this process is white balance. After calibration, all previous errors were corrected in both HD and 4K content, and most errors no longer fell significantly outside the value of "2". This means a much more balanced and natural colour reproduction, which certainly affects the viewing comfort. In terms of gamma, the drop has been greatly mitigated, resulting in a more consistent tone reproduction across various scenes. However, the EOTF curve has not improved significantly 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 can affect the perception of certain materials. Nevertheless, despite these minor shortcomings, the overall shape of the picture is definitely better after calibration. The TV has gained quality, and the improved white balance along with reduced gamma issues means that users can enjoy a more realistic and pleasant visual experience. Further adjustments to the settings could improve the picture quality even more, but already the TV is demonstrating its capabilities, meeting the expectations of many users.

Nevertheless, an important aspect in assessing image quality are tonal transitions. To achieve a clear image free from posterisation effects, the television must demonstrate very good algorithms for smoothing out colour gradation. We must admit that the applied feature in TCL C855 called "Gradual Smoothing" is one of the better ones we have had the opportunity to test. Practically every scene performs very well here, and nothing can be faulted. The best example of this is the scene from "The Green Knight", which is the most demanding due to the vast number of fine and subtle transitions in the fog. The C855 effectively smooths everything present in the scene and allows the viewer to experience its entire suspense. The only moment where a slight posterisation can be noticed is in a frame from the film "The Green Knight", where the reds in the top left section of the screen contrast against each other.

During the fluidity tests of tonal transitions in Xiaomi A Pro 2025, the gradation proved to be close to ideal. In most of the test sequences, there were no noticeable issues. Only in the scene with red water did very cosmetic imperfections appear, which, however, have no significant impact on the overall image quality. Both colour and grey gradients were reproduced with almost perfect precision, making this TV model a very good choice for those who pay attention to this particular feature of a television.

Once again, we will look at the function of smoothing tonal transitions, but this time also image scaling. The latter is particularly important when watching materials of lower quality, such as some TV programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes in the previous test, it performed splendidly and smoothed out practically all the choppiness, but here it had problems. Using the menu responsible for the operation of this function, we found that none - not even the strongest - setting helped.

The image scaling in TCL C855 is characterised as one of the best we have had the opportunity to test so far. The image is sharp, but in a way that could be described as natural to our eye. Even small, fine branches do not have jagged contours, and there is no white halo around figures, which is characteristic of weaker scaling systems.

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

In the case of the test shot with the model and numerous branches in the background, the Xiaomi A Pro 2025 showcased its capabilities in the context of digital processing. Adding artificial sharpness to this scene made the details of the model clearer, and her hair appeared more detailed. However, delicate contours appeared around the branches in the background, which were a result of digital intervention. While this enhances the overall impression of details, excessive sharpness can make some elements of the image seem unnaturally emphasised.

The maximum refresh rate that we can set on TCL C855 is 144 Hz. Naturally, this is only possible when connecting the TCL C855 TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a high level of motion dynamics. For those who require high fluidity of image, the manufacturer has implemented a multi-level motion smoother. It has been divided into two separate sliders that adjust the sharpness of moving images (Blur Reduction) and judder (Judder Reduction). Both sliders can be set in the range of 0 to 10, with each level affecting the degree of smoothing, so everyone can find their sweet spot. We present a setting that allows for slight smoothness without the soap opera effect.

The panel of TCL C855 features a very good response time. This is especially important, as VA panels often have issues with so-called ghosting, which is the effect where a black halo can be noticed behind a fast-moving object.

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

The TCL C855 television is equipped with full HDMI 2.1 ports with a bandwidth of 48 Gb/s. During our tests, we confirmed the seamless operation of all functions that come with this standard. As you can see, all the checkboxes light up green, which will certainly be appreciated by gamers, both console and those using the television as a computer monitor. Additionally, the TCL C855 supports both AMD FreeSync and NVIDIA's G-Sync, which can be easily activated in the graphics card settings. Users with very powerful setups can provide a 144 Hz signal to the C855, which the television handles effortlessly. It's also worth mentioning the implementation of the HGIG mode, which, due to the shortcomings of the "Game" mode, is overly bright, making it difficult to configure properly on-screen. Fortunately, the television performs excellently with the Dolby Vision format.

The TCL C855, as one of the first manufacturers, has equipped its televisions with a special GameBar feature that allows extensive setting changes on the fly, without the need to exit the game. It includes functions such as an additional crosshair grid, black level correction, and settings for individuals with disabilities. In the photo, we see the next generation of this solution.

In summary, the TCL C855 television will be an ideal solution for those looking for a screen for any kind of electronic gaming. With all the features supporting such entertainment, it is incredibly engaging. It should also be emphasized that it has very low input lag, regardless of the selected settings, including with the Dolby Vision HDR format.

Xiaomi A Pro 2025 offers several features useful for gamers, including Game Bar, which differs from the typical “dashboards” with interfaces found in other manufacturers. With this, users can quickly access game-related settings, which is convenient during intense gaming sessions. The TV also supports automatic low-latency mode (ALLM), meaning it automatically switches to a mode optimised for gaming, reducing signal delay. Unfortunately, it lacks support for HDMI 2.1, limiting the connection capabilities for 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 images 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 gaming solutions.

The lag time of the TCL C855 is astonishingly low in every scenario. Even the most passionate gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, clocking in at just 7 ms. Furthermore, the lag at these same settings, but with Dolby Vision HDR enabled, remains at the same level, which isn't so obvious with competing models. Therefore, the TCL C855 deserves the highest rating and recommendation.

Xiaomi A Pro 2025 delivers outstanding performance, regardless of resolution or HDR mode. With measurements as low as 15 ms, this TV ranks among the best in terms of responsiveness.

TCL C855 when connected to a computer as a monitor performs very well. This is thanks to the very low latency between the mouse-eye-screen and the excellent readability of fonts, which comes from the proper implementation of chroma 4:4:4 at all resolutions, including 4K@144Hz. The subpixel layout is BGR, which does not negatively impact usage in Windows. However, the situation may change when using macOS or other software that may not be able to adjust fonts to this subpixel layout. Additionally, the TV has minor issues displaying fonts on a black background, for which we deducted some points.

In the category of collaboration with PCs, Xiaomi A Pro 2025 performs very poorly. The fonts are of low quality, and their display on the screen is often problematic. Dithering is ubiquitous; when zooming in on the fonts against a dark background, they are displayed in three colours, which is definitely eye-catching and can significantly hinder comfortable use of the device. Such issues can be a significant drawback for users planning to use the television as a computer monitor.

A widely known drawback of VA panels without an angle coating is their poor performance regarding viewing angles. The same is true for the TCL C855, where even a slight off-axis shift leads to significant image washout and colour degradation.

In the viewing angles category, Xiaomi A Pro 2025 with its VA panel simply performs poorly. While directly in front you can enjoy better blacks, the image loses quality from side perspectives. Our specialists found during the testing of the television that sitting a metre away from the device, the image on the right side is brightened and desaturated. However, moving a bit to the side improves everything, highlighting how significant the difference in image reception is depending on the viewing angle. All this makes the viewing experience in a larger group potentially less satisfying.

The glossy finish of the panel on the TCL C855 prevented it from achieving the highest rating for TV performance during daytime viewing, although it is precisely due to this that the blacks during the day are very good. Thanks to the high brightness in SDR content, the actress's face strongly stands out through reflections. However, a downside of the panel is that light hitting directly on the TV "spills" out rather than being contained in one spot. Generally speaking, if sunlight doesn't hit the panel, the TCL C855 will be a very good choice for brightly lit rooms.

Xiaomi A Pro 2025 presents itself as average. The panel coating is satin, which may help reduce reflections, but the suppression of glare is moderate. The brightness of the television is only 250 nits, which is relatively low compared to other models on the market. As a result, during sunny days or in brightly lit rooms, the image quality may suffer, and details may be hard to discern.

TCL C855 operates on the Google TV system, which is a significant advantage compared to TVs equipped with proprietary systems from manufacturers, where installing applications from a USB drive can be challenging or often downright impossible. With Google TV, we have the option to install almost any application, both from the official store and directly from internet repositories via APK files.

This system also offers many conveniences in terms of control. We can connect a keyboard with a touchpad, which significantly simplifies entering queries. Additionally, thanks to integration with Google, we can utilise voice control features using the remote, which works very well, although there can be minor issues with translating functions and options. It’s worth mentioning that Google TV regularly receives updates that improve functionality and introduce new options. We can also confirm that according to reports from users of older models, the software can have its off days, and sometimes it does have its "bad day".

In summary: Google TV is currently one of the most popular systems on the market. Thanks to its powerful CPU, it runs very smoothly, does not freeze, and has no issues with stuttering for a significant part of its usage. This is definitely the best option for those who want to make the most of the TCL C855 TV’s capabilities and appreciate the openness of the system.

In the functionality category, Xiaomi A Pro 2025 stands out with the Google TV system, which is one of its biggest advantages. This allows users access to a wide range of apps and streaming services, significantly enhancing the convenience of using the television. The Google TV system also offers a voice assistant that facilitates navigation and allows for quick content searches without the need to dig through menus. One of the key strengths of this system is the ability to download virtually unlimited apps from the Google Play Store, enabling personalisation of the television according to individual needs. Users can install apps for streaming, gaming, and various tools, making the television a multimedia entertainment hub. However, it is worth noting that this model lacks recording functions and AirPlay, which may be disappointing for some users. Additionally, there are quite significant lags in the operating system, affecting the ease of use. On the positive side, it also features the ability to pair other peripheral devices via Bluetooth and a remote that does not require aiming at the screen, which significantly improves user comfort. Despite some shortcomings, Xiaomi A Pro 2025 has the potential to meet the needs of users looking for a modern television.

The default media player on the TCL C855 handles practically all the media we've prepared for it very well. Almost every video format is supported. However, an important downside may be the lack of a font colour change feature. There are hardly any issues with photos and their maximum resolution. It's definitely worth noting the absence of support for Apple's HEIC and SVG files. On the other hand, we can play audio files without any problems, and we don't think many of you are using AIFF or DSD64. One undeniable advantage of the C855 and its operating system is that at any time we can download another player from the app store that will play anything.

Xiaomi A Pro 2025 offers a decent built-in media player that meets the basic expectations of users. However, the TV has its drawbacks and sometimes encounters issues with playing certain file formats, which can be frustrating. Fortunately, with access to Google Play Store, users can easily download alternative players that better meet their needs. In our test of the Xiaomi TV A Pro 2025, we demonstrated that its compatibility with applications is high, and additional media playback applications work flawlessly. It is also worth highlighting that the Xiaomi TV A Pro 2025 is equipped with the Android TV platform, enabling access to a wide range of applications and streaming services. Installing alternative media players enhances the overall functionality of the device and eliminates format compatibility issues. As a result, Xiaomi A Pro becomes a more versatile television that can meet the diverse expectations of users, even those with higher demands regarding media playback.

When assessing the sound on the TCL C855, we pay attention to several key aspects, such as whether the tones are clearly audible and do not interfere with each other, as well as whether none of them dominates the others. In the case of the TCL C855, the sound performs well – it is balanced and does not evoke any negative feelings. Generally, the sound is simply good.

For those with a home theatre system, the TCL C855 offers a wide range of audio codecs, including the two most important ones: DTS-HD Master Audio and Dolby Atmos. This ensures high sound quality that will satisfy users seeking better audio experiences.

When it comes to sound, Xiaomi A Pro 2025 pleasantly surprises, especially considering its price. The sound quality is really solid, and the audio does not deviate from what one might expect in this class. Additionally, the TV supports DTS audio formats, which are often missing in much more expensive TVs. It's worth noting that this rating is subjective and may vary depending on individual preferences.
