Compare: TCL C655 Pro vs Xiaomi S Mini 2025

TCL C655 PRO is an extension of the basic model in this series, and although the name may suggest only slight differences, the addition of "PRO" truly means a lot here. The biggest change compared to its less advanced sibling is the picture quality. The manufacturer decided to implement local dimming technology, which significantly improves black levels and contrast. The TV is able to offer us a more refined picture. Thanks to this, TCL C655 PRO clearly outperforms the more basic version in this regard. The applied QLED panel further enhances the coverage of a wide color gamut, offering vibrant and saturated colors, which works brilliantly in both movies and dynamic content like games. In terms of gaming, just like the basic version, TCL C655 PRO offers a range of useful features for gamers – including ALLM, VRR, and Game Bar – which greatly enhance gameplay comfort. The TV can also adjust the screen refresh rate to a lower resolution, meaning that despite support for 4K at 60 Hz, in Full HD or 2K you can enjoy a smoother picture thanks to 120 Hz. In everyday use, the Google TV operating system performs excellently. The intuitive interface, personalized recommendations, and wide access to streaming apps like Netflix, YouTube, and Disney+ make the TV enjoyable to use. Because of this, we easily forgive the lack of recording and picture-in-picture (PiP) features, which doesn’t pose a significant problem given the rich app offerings. If we are able to stretch that slight price difference, we definitely recommend the TCL C655 in the PRO version.

Xiaomi, well-known as a giant in the smartphone market, has decided to compete for the attention of high-end tech enthusiasts by presenting a MiniLED backlit television. The S MiniLED 2025 model looks truly impressive on paper. An enormous number of dimming zones provides excellent contrast, and the brightness, reaching impressive levels, can impress both in high-quality HDR materials and in older SDR. The television performs exceptionally well where motion smoothness is key. The high refresh rate panel and low input lag make it a good choice not only for sports fans but also for gamers. Support for features like ALLM and GameBar further enhances the gaming experience. Google TV on this television works as it should – quickly, smoothly, without unnecessary stutters, which we couldn't say about the model A Pro 2025. Additionally, with such an extensive app library, it will satisfy even the most demanding user. However, not everything looks so good in practice. Despite solid hardware specifications, the television has its quirks. The biggest issue is the algorithms managing the dimming zones, which can be quite irritating when watching movies in the evening. The performance of individual zones is overly noticeable in dynamic scenes, which can effectively distract our attention from the image. Problems also arise in more demanding HDR scenes despite the truly impressive brightness. Small bright elements often lose brightness, which spoils the effect that high-quality imagery should provide. The system is also not without its shortcomings – features that enhance images in lower-quality materials work unevenly, and some options in Google TV are poorly translated or even untranslated. Xiaomi S MiniLED 2025 has enormous potential, but in its current form, it seems underutilised. It is clear that Xiaomi wanted to do something really good, but a few significant shortcomings lead to a mixed final outcome. A device with high aspirations that needs better software to truly shine. It is an ideal television for brighter rooms, where high screen brightness plays a key role, and issues with local dimming become less noticeable. It will also perform excellently as a screen for gamers and for those who value the versatility and functionality of the Google TV system.

The TCL 655 PRO TV, equipped with a VA panel, provides solid contrast; however, the key role in improving image quality here is played by local dimming technology. The tested 55-inch variant has 84 backlight zones, which significantly enhance the contrast compared to the model without the "PRO" suffix, and this effect is clearly visible in the first three tested scenes. It is worth noting that larger versions of this TV naturally have more zones, which translates to even better contrast. Of course, as with any LCD TV, certain shortcomings remain – particularly noticeable on tested screens 4 and 5, where smaller bright elements lose quite a bit of quality. Nevertheless, considering the price of the device, the TCL 655 PRO makes a big impression and stands out well in the categories of black and contrast.

Xiaomi S MiniLED is one of the most affordable televisions with MiniLED technology available on the market. The model we tested, sized at 55 inches, is equipped with as many as 308 local dimming zones, which is impressive for such a price. Additionally, it features a VA panel, which inherently offers significantly better contrast than IPS panels. On static test screens, the television performed excellently, achieving an impressive contrast ratio of 182,000:1 in the film Oblivion. Blacks were deep, and details in both bright and dark areas of the image were clearly separated. However, in more demanding scenes where the image is dynamic, the situation begins to complicate.

Where lies the problem? The main cause is the local dimming algorithms. Although on static images, their effects are promising, during movie playback – which reflects the television's natural working conditions – they operate too aggressively. In dynamic scenes, like those from the tested film, one can see how the individual dimming zones "work and flicker," which detracts from the viewer's sense of image coherence. This effect is particularly noticeable in motion, when bright objects move against a dark screen. As a result, although Xiaomi S MiniLED offers fantastic contrast on paper, in practice, the effect is less satisfying. The aggressive operation of the algorithms ruins the perception of dynamic scenes, making the television perform average in this category. This is a good example of how MiniLED technology requires not only a good specification but also adequate optimisation.

In the HDR effect quality category, the television TCL 655 PRO shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoying HDR effects, which can be clearly seen in scenes such as the first one from the movie Life of Pi or the final shot from The Meg. However, the limited number of dimming zones causes some issues. 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 more. The dimming algorithm aims for deep blacks, but at the cost of brightness – which at those moments can cause a drop in brightness of even half. In these more challenging scenes with small elements, it's hard to find any praise, and the HDR effect resembles SDR. Nevertheless, the coverage of the colour palette deserves recognition, which, like in the version without the PRO suffix, is at a very good level.

Since Xiaomi S MiniLED boasts an impressive 308 zones of dimming, it's time to see how it performs in HDR tests. Starting with luminance, or the ability to display bright scenes, the television achieved nearly 1000 nits of brightness – a result that can be considered outstanding in this class. But do these numbers translate to real-life experiences in film scenes? In the case of less demanding shots, such as those from the film The Meg, the television indeed delivered excellent results, reaching up to 900 nits. Such values are impressive and can truly convey the strength of HDR effects.

Unfortunately, just like with contrast, there were some issues. When smaller, brighter elements appear on the screen – as in challenging scenes from Sicario 2 – the aggressive action of the dimming zones ruins the entire effect. Brightness in these moments drops to just 100 nits. That is definitely too little to convey the full magic of HDR. Instead of a dynamic and detailed image, the viewer gets a muted, almost flat impression, which takes away all the enjoyment of the viewing experience.

In summary, if we're looking for a television with high brightness for watching movies during the day, the Xiaomi S MiniLED will easily fulfill that task. However, its inability to precisely manage the dimming zones makes watching movies in the evening, especially during demanding HDR scenes, potentially more frustrating than satisfying.

Each of our TV tests is conducted in movie mode, which usually offers the best colour reproduction. However, even this mode is not free from issues, as we noted in 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 overly emphasise the colour blue. As a result, the image can give a sense of artificial sharpness, which proves to be uncomfortable for the eyes over a longer period. The brightness characteristics also leave much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, making the overall presentation appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we have detailed in the paragraph regarding HDR effects.

Xiaomi, like many manufacturers, offers a wide range of picture modes. On the S MiniLED, we can find both IMAX Enhanced and Filmmaker. Our tests were conducted in Filmmaker mode, which theoretically aims to reference the image, but the reality turned out to be somewhat different.

Let’s start with the SDR material tests. Here the TV had quite a few problems, especially with white balance. The noticeable dominance of red made the image appear too warm, and all colours gained a reddish hue. This was particularly evident in the comparative scene from the film Star Wars. The brightness characteristic (gamma) also left much to be desired – instead of a smooth transition, we had a real "rollercoaster," with visible excessive brightening of the screen.

In 4K materials, the situation looked considerably better. The white balance, though still not perfect, was much more balanced, with a slight dominance of red and blue, but no excessive impact on the overall perception. The EOTF curve (responsible for brightness in HDR) showed some brightening in the brightest parts of the image, which was noticeable in the test scene from the film Pan that we described above. These brightening effects may disturb the precision of the image, but in 4K, the overall effect was far more acceptable than in SDR.

Although Xiaomi S MiniLED can pleasantly surprise in 4K materials, its factory settings in SDR require significant corrections, especially regarding white balance and brightness. It's definitely a TV that would benefit from calibration.

After calibrating the TCL 655 PRO television, there is a noticeable improvement in white balance, where the tendency for the screen to be overly pink has been completely eliminated, which was previously noticeable in factory mode. The picture has taken on more natural tones, especially in white and bright elements, which positively affects the overall image perception. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image appear washed out. Nevertheless, there are still some issues with the EOTF curve, which are difficult to eliminate due to the television's construction and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. However, despite this minor fault, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

Xiaomi S MiniLED 2025 is a television that gains a whole new life after calibration. The results are truly impressive and show how much potential this model has.

In SDR mode, the white balance is almost perfectly aligned. The errors are so minimal that in many cases they can be considered negligible. This is confirmed by the Colour Checker palette results, where errors did not exceed 2 ΔE – a truly rare outcome. Gamma also performs very well, although there are slight brightening effects in the darkest elements at the beginning of the graph. However, this is a minor exception that does not significantly affect the viewing experience.

In 4K HDR material, calibration also brought visible improvements, particularly in white balance. The image looks natural and consistent. However, the characteristic of brightness remains an issue. EOTF analysis in film materials shows that the television tends to overly brighten or darken the smallest elements on the screen. This is the effect of limitations in the dimming algorithms that we previously discussed regarding HDR and contrast testing. Unfortunately, this is a technical feature of this model that cannot be completely eliminated.

Despite this minor flaw, calibration has allowed us to extract the maximum capabilities from this television. The image now looks phenomenal, and its quality impresses in every type of material. Xiaomi S MiniLED 2025 demonstrates that with the right settings, it can compete with more expensive models.

Tonal transitions are really quite good and would deserve a high rating (8), however, the score has been clearly lowered for another reason - the image is artificially sharpened despite the "sharpness" setting being at 0. As a result, the image is unpleasant to look at.

The fluidity of tonal transitions in Xiaomi S MiniLED 2025 looks very good. Even in the theoretically most challenging scene with red water, the television performs excellently – we did not notice any major issues. Minor imperfections occur in scenes like Kingsman or The Martian, where you can see subtle colour blending. Nevertheless, Xiaomi stands out in this category, offering one of the best qualities of tonal transitions in its price range. This is definitely a strong point of this television.

The TCL 655 PRO television handles tonal transitions quite well in lower-quality material. The "Gradual Smoothing" feature at low settings effectively smooths tonal transitions, but this comes at the cost of losing some essential details, such as the texture of objects. On the plus side, it doesn't negatively affect film grain, which helps maintain a natural look to the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a bolder image. However, individuals who favour a softer, more subtle look may find this a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and cuts off the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

When it comes to tonal transitions in lower-quality materials, such as YouTube or television, the Xiaomi S MiniLED comes with a feature called “Colour Contour Removal.” In the "low" setting, it works quite well, but its effectiveness can be uneven. Sometimes it appears as if the TV struggles to smooth things out, which creates a bit of dissonance. On the plus side, we didn’t notice any visible side effects, although given the instability of this feature, one might suspect that unexpected issues could arise in certain situations.

Image scaling also comes across as average. There’s slight jaggedness, especially on thin elements like branches, and text can be a bit ragged. It may not be overly bothersome, but a more discerning eye will certainly catch these imperfections. Overall, most users should be satisfied with the scaling and smoothing quality, but the TV may not satisfy those who expect perfection in every frame.

The TCL C655 PRO television is equipped with a 4K display with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows for adjusting the smoothness of the picture, giving the user the choice between smoother motion and a cinematic, frame-by-frame effect. Furthermore, the television performs well with lower resolution content, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will surely appeal to gamers who can enjoy a smoother image, albeit at the cost of lower resolution.

Xiaomi S MiniLED 2025 is equipped with a 4K@120Hz (1080p@240Hz) refresh rate panel, providing sufficient smoothness for both watching dynamic sports broadcasts and playing the latest games. This level of refresh rate makes the image look fluid, even in the most intense scenes. Additionally, the television offers a "Motion Smoothing" feature that allows users to adjust the way the image is displayed in films. We can choose a more choppy effect, typical for cinematic experiences, or a smoother one, resembling the so-called "theatrical effect". As a result, every user can tailor the settings to their preferences and enjoy smooth images in their favourite content.

The TCL C655 PRO TV offers an almost perfect set of features for gamers, supporting all key technologies that significantly enhance gameplay comfort. The ALLM feature automatically switches the TV to low-latency mode, improving responsiveness and minimising signal delay – particularly important in fast-paced titles. VRR synchronises the screen refresh rate with the frame rate generated by the console, eliminating screen tearing and ensuring smoother gameplay.

Support for Dolby Vision in game mode enables more detailed colour and contrast representation in games that support this format, while the Game Bar provides quick access to essential settings, such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for high refresh rate enthusiasts.

Xiaomi S MiniLED 2025 is a television that has a lot to offer gamers. With two HDMI ports boasting 48 Gbps bandwidth, we can easily connect modern consoles or PCs, utilising their full potential. Additionally, the ALLM feature automatically switches the TV to low latency mode – something we appreciate during fast-paced gaming without annoying lags. No matter what we connect, it runs smoothly, and the TV handles various resolutions exceptionally well. There’s also the GameBar, which may not look as flashy as the "bars" on competing models, but makes up for it in practicality. It’s a straightforward settings panel that allows us to quickly change the most important options or check stats – a perfect solution when time is of the essence.

However, we must admit that navigating the TV itself – or rather, finding gaming features – was quite a challenge for us. We approached the Xiaomi S MiniLED 2025 test several times to locate all the necessary options. The hidden menu allowed us to discover the "GameBoost" feature, which enables switching the TV to 240 Hz mode, activating VRR, and allows for enabling the image in HGIG mode.

In summary, the Xiaomi S MiniLED 2025 is a TV that definitely deserves praise in the gaming equipment category. Its rich set of features – 240 Hz mode, VRR, HGIG, and "GameBoost" – provides an exceptional gaming experience. Unfortunately, the intuitiveness of the menu itself leaves much to be desired and can pose some challenges for the average user.

The TCL C655 PRO TV offers exceptional response times across all supported resolutions and refresh rates. Notably, it supports Dolby Vision with a response time of 13ms, which is rare among competitors. This allows gamers to enjoy excellent responsiveness even when using advanced HDR effects, significantly enhancing the gaming experience.

Input lag in Xiaomi S MiniLED 2025 is one of its biggest advantages. 8 ms for 120 Hz content and 17 ms for 60 Hz are simply outstanding results that will satisfy even the most demanding gamers. Moreover, the Dolby Vision mode in games deserves praise. Unlike many competing models, Xiaomi maintains a low input lag even in this mode, making it an excellent choice for lovers of high-quality HDR gaming experiences.

Collaboration with PC on the TCL C655 Pro TV works quite well, especially thanks to the support for chroma 4:4:4, which ensures good readability of fonts. This is an important advantage if the TV is to be used as a monitor for office work, where precision in displaying text is crucial. Additionally, the low input lag provides smooth performance, which will be appreciated by both gamers and users who need a quick response to mouse or keyboard movements.

One of the minor drawbacks that can be noticed is the fact that in vertical lines, there is occasionally a one-pixel blackout. This can make letters appear slightly broken, which in certain situations might lower work comfort a bit, although generally, this issue should not be very bothersome for less demanding users. The TV does not support 120Hz for its maximum resolution, hence the lower rating compared to higher models. However, TCL has ensured that you can enjoy smooth gameplay at 120Hz in lower resolutions such as 2K and FullHD.

Xiaomi S MiniLED 2025 is a good choice if you need a TV for computer work. The fonts are very clear thanks to 4:4:4 chroma support, making it ideal for office work or browsing documents. It also performs excellently in gaming – high refresh rates, G-SYNC, and low input lag ensure smooth gameplay, which will satisfy most gamers.

The viewing angles on the TCL C655 PRO, as with a VA panel, are quite limited. Compared to IPS panels, which maintain image quality better regardless of the viewing angle, the VA panel in this model quickly loses contrast and colour saturation with just a slight deviation from the axis. Watching at an angle causes blacks to appear more grey, and colours lose their depth and intensity. For this reason, the television is better suited for rooms where viewing occurs mainly straight on. It is not a television that is an ideal choice for large spaces where viewers may be sitting at various angles.

In terms of viewing angles, Xiaomi S MiniLED 2025 is not impressive. This is a typical problem with VA panels, which struggle without additional coatings to widen viewing angles. The image begins to lose quality when watching the TV from the side – colours fade, and contrast significantly drops. However, the advantage of VA panels is their much better contrast compared to IPS panels, which in turn win when it comes to wider viewing angles. This is a classic compromise where one has to choose between better blacks and a more universal image seen from different spots in the room.

TCL C655 PRO offers quite decent brightness, reaching around 520 nits, which makes using the TV during the day comfortable. This brightness allows for good image visibility even in rooms with higher sunlight exposure. Although the TV performs well in such conditions, the satin finish of the panel has only average capabilities for reducing reflections. In very bright environments, reflections may occur that somewhat impair image visibility, especially in scenes with lower contrast.

Xiaomi S MiniLED 2025 is equipped with a satin finish on the display, which moderately handles glare reduction. On the screen's surface, you can see light reflections, which may be somewhat distracting in bright rooms. However, the key element that saves this television in daytime use is its brightness. With a value of 841 cd/m², the screen performs flawlessly even in very sunlit interiors. This is more than enough to comfortably watch television, movies, or sporting events. Importantly, the television also handles more demanding content, such as winter sports, where the dominant white can pose a significant challenge for other televisions. Here, Xiaomi definitely excels.

The TCL C655 PRO television runs on the Google TV system, which is an extension of the popular Android TV. Google TV provides personalised content recommendations based on viewed materials and user preferences, granting easy access to movies, series, and applications. With a clear interface, navigation is simple, and access to popular streaming apps like Netflix, YouTube, Prime Video, and Disney+ allows enjoyment of a wide range of content. The system also supports integration with the Google ecosystem, enabling control of the television via voice commands using Google Assistant and synchronisation with other smart home devices.

The TCL C655 PRO offers additional features that enhance user comfort, such as support for Apple AirPlay, allowing quick streaming of content from Apple devices directly to the TV screen. Additionally, the ability to connect peripherals via Bluetooth – such as keyboards, mice, or headphones – makes usage even more convenient. Unfortunately, this model does not have a USB recording feature or a picture-in-picture (PiP) option, which may be a disappointment for those accustomed to these conveniences in traditional television. Nevertheless, the TCL C655 PRO offers many modern solutions that facilitate daily entertainment.

The design of the TCL C655 PRO television presents a modern look, with elegant and slim metal bezels that add solidity and aesthetic appeal to the device. The overall appearance is very good and will certainly fit into most interiors. Although the bezels are minimalist, the television itself is not among the thinnest on the market, especially compared to Korean competitors who often provide even sleeker designs.

Xiaomi S MiniLED 2025 is a television that stands out thanks to the Google TV system. It offers access to the most popular streaming services, music apps, and various useful features that significantly enhance everyday use of the TV. For those who enjoy personalisation, the system also provides plenty of configuration options.

The built-in voice assistant operates smoothly – we can not only control the TV but also ask for the weather forecast or set a reminder for the next day. Unfortunately, we noticed during testing that some functions have trouble translating into Polish, which can be annoying, especially for those less proficient in navigating the settings. Despite this, the overall impression is very good, and minor shortcomings can be improved in updates.

The device handles connectivity well. Wireless connections with Windows computers or Apple devices run smoothly, and thanks to Bluetooth, we can easily connect headphones, keyboards, or other accessories. The remote is simple and convenient – it works from any position, so aiming at the screen is not necessary. However, there are some shortcomings. If someone frequently uses traditional television, they might miss the recording functions from tuners or the PiP (picture in picture) option. This somewhat limits the possibilities, but for those focusing on streaming and modern features, it won’t be a major issue.

Xiaomi compensates for these shortcomings with an excellent operating system. Google TV is one of the most advanced and intuitive systems available on the market, which makes the television perform really well in daily use.

Thanks to the built-in player, the television is capable of playing most file formats found on external drives, making it a versatile tool for consuming multimedia. However, there may be some limitations in supporting certain formats, which can be annoying for more demanding users. Fortunately, the Google TV system allows for the installation of other media players from Google Play, which helps eliminate compatibility issues. As a result, users have the option to choose applications that best meet their needs, significantly increasing the functionality of the television.

The basic file player in Xiaomi S MiniLED 2025 performs its task for simple video materials. However, a noticeable drawback is the lack of support for Polish characters, which can be problematic for individuals using subtitles.

Fortunately, the presence of the Google TV system provides a way to easily work around this limitation. It allows for the installation of alternative file playback applications that handle Polish characters and offer significantly more advanced options. As a result, the limitations of the built-in player are not as burdensome as they may seem.

The sound on the TCL C655 PRO television is quite good, thanks to the 2x15W audio system supported by a 20W subwoofer branded by Onkyo. This results in fuller sound and deeper bass, which positively impacts the overall audio quality. However, one should not become overly enthusiastic – the television cannot replace a dedicated soundbar, especially for more demanding users expecting cinema-quality audio.

Xiaomi S MiniLED 2025 sounds really pleasant, and even offers a light bass, reminiscent of the sound known from the lower model, the A Pro 2025. The sound is well balanced, making watching movies or listening to music comfortable, even without additional audio equipment. Interestingly, the television seamlessly supports audio formats like Dolby Atmos and the less common DTS:X. This allows you to connect a home theatre system or soundbar and enjoy spatial sound without any difficulties. A nice addition is also the presence of a standard speaker jack connection.
