Compare: Samsung QD-OLED S90D / S94D vs Xiaomi S Mini 2025

Samsung S90D or otherwise S94D has pleasantly surprised us in many ways. It offers excellent picture quality as befits a TV with an organic matrix. Depending on the size, the television can have different types of OLED panels. In the model we tested, the 65' version with a QD-OLED panel, the blacks are deep, and the colours are vivid and intense. The brightness of the screen, thanks to quantum dot technology, makes HDR effects very impressive. Watching dynamic scenes full of details is completely immersive. This is an ideal choice for those who want to enjoy cinema at the highest level at home. However, we noticed that the factory colour settings might require adjustment. But after the appropriate calibration, the TV showcases its full potential and competes with the best televisions, even above its price range. This model stands out with excellent viewing angles - better than the WOLED panel variants. The picture is clear and colourful from any position in the room. The Tizen operating system makes everyday use of the TV easy. Navigating apps and streaming services is simple and intuitive. Additionally, support for AirPlay and access to the SmartThings ecosystem enhance the multimedia capabilities of the device. When it comes to motion smoothness, the 144Hz panel handles fast scenes excellently and additionally eliminates motion blur. Watching sports or dynamic movies is a pleasure. For gamers, it offers support for HDMI 2.1 and low input lag, making it a great choice for console gaming. Despite numerous advantages, we noticed a few drawbacks. In bright rooms, the blacks on the QD-OLED panel lose their depth. This can be noticeable when watching during the day. Another somewhat less significant issue could be the readability of fonts when using a PC. It could be better; some texts are less sharp compared to other models. Nevertheless, the 65' Samsung S90D or S94D is a television that combines exceptional picture quality, motion smoothness, and innovation. It is one of the best options in the premium segment that will meet the expectations of both cinema lovers and gamers.

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.

Samsung S90D, thanks to the use of a QD-OLED panel, offers excellent contrast, which is one of its greatest advantages. In QD-OLED technology, each pixel emits its own light, allowing for perfect blacks and precise detail reproduction in dark scenes. Unlike traditional LCD panels with backlighting, where blacks often appear greyish, turned-off pixels in QD-OLED remain completely black. As a result, the television provides a dynamic, realistic image with exceptionally deep contrast. For example, in scenes from "Oblivion," the Samsung S90D brilliantly captures the intensity of the lantern lights, highlighting details in the bright areas of the image, and in "The Revenant," it perfectly showcases the character against the backdrop of a deep, black forest scene, emphasizing impressive contrast reproduction. It is worth noting that in the Samsung S90D model, only this specific size is equipped with the QD-OLED panel produced by Samsung Display, setting it apart from other versions. Nevertheless, regardless of the panel used, the blacks on this television will always be perfectly black thanks to OLED technology, which turns off pixels for absolute blackness. This means that in categories such as black levels and contrast, the S90D delivers excellent picture quality regardless of the type of panel.

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, Samsung S90D achieves remarkable results. On the luminance chart up to 10% window, the TV exceeds the magical threshold of 1000 nits, which is an impressive outcome. However, in the film scenes we tested, these values were slightly lower. Additionally, in the case of a scene with fullscreen sunlight glare, brightness drops to around 500 nits, but it still remains at a very good level. It is worth mentioning that this model stands out with very high colour gamut coverage, thanks to the QD-OLED panel used, which gives it an advantage over TVs with WOLED panels that cannot achieve such a wide spectrum of colours.

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.

Samsung 65 S90D with a QD-OLED panel has been tested in Filmmaker mode, which the manufacturer has been using for years to provide the best possible picture settings. In this mode, the TV offers a fairly decent image but with some shortcomings worth noting. In terms of white balance in HD content, viewers may notice a dominance of the red color. This effect can lead to the impression that certain skin tones appear unnatural and the overall scene will be too warm, which in turn can affect immersion in the watched material. In scenes where subtle differences in color are crucial, these distortions can be particularly noticeable. Similar sensations may also occur in 4K HDR content. Changes in white balance in this case can be analogous, with a noticeably smaller deviation in red color. This can also cause certain details and colors to not be fully represented, making the image lose its naturalness.

When it comes to contrast, the gamma presents quite well, however, some errors are still noticeable. Gamma values are below the reference level of 2.4, which can result in bright areas of the image being washed out and dark areas lacking detail. This limitation can cause some scenes to lack depth and detail, which in turn affects the overall presentation quality. On the other hand, the EOTF curve related to contrast in 4K HDR content performs really well, showing that the TV can effectively convey differences in brightness. Nevertheless, it is worth noting that these values are slightly below the ideal level on the graph, indicating the need for further optimization in this regard.

Samsung S90D in Filmmaker mode offers solid color reproduction, but requires some adjustments to fully realise the potential of the TV, especially in the context of different types of content.

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 TV, the Samsung S90D in film mode gains quality more than one might expect. The white balance for HD and 4K HDR content has been adjusted to near perfection. Although minor shortcomings can be noticed, they are subtle enough that they don’t significantly impact the overall picture quality. The colours have become more harmonised, aiding in the natural reproduction of details, particularly in scenes that require precise colour representation. It is worth noting that this model, in this size, uses a QD-OLED panel which offers broader colour gamut coverage compared to other sizes of this model that are equipped with a WOLED panel.

The contrast has also significantly improved. After calibration, the gamma graph is much closer to the expected line, providing a better balance between light and dark tones in the picture. The EOTF curve, which before calibration indicated issues with overexposed scenes, now shows significantly better results. This effect allows for the retention of more details in the bright areas of the image, especially in HDR materials.

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.

In the category of fluid tonal transitions, the television S90D exhibits significantly better results than its counterpart with a WOLED panel. Thanks to the use of a QD-OLED panel, this model provides more consistent and natural transitions between colours. Although some minor imperfections were noted during testing, they are subtle enough not to impact the overall visual experience. When watching various video content, tonal transitions are smooth and harmonious, allowing viewers to enjoy the depth and detail of the image without irritating distractions. In tested scenes where colour changes are particularly important, such as in landscapes or dynamic sequences, the television Samsung S90D performs excellently, rendering differences in shades with adequate precision.

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 television handles tonal transitions excellently, allowing colours to flow smoothly into each other, creating a natural image. The built-in noise reduction feature can further enhance these transitions, which can be useful in certain situations. However, it is worth remembering that activating this option may lead to excessive smoothing of the desired film grain structure, which in turn can affect the authenticity and atmosphere of the image. Therefore, caution is recommended when using this feature to avoid losing the character and depth of the content.

The Samsung S90D model effectively processes materials in lower resolutions. This can be seen in the displayed image. The model's silhouette is clear and naturally reproduced, with details well preserved. Additionally, the branches of the trees are well-defined, showing no visible jagged edges that could degrade the quality of the image. Thanks to effective upscaling, even lower resolution materials look attractive on the screen, which will surely please users enjoying a variety of content sources, such as standard cable or antenna television.

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.

Samsung S90D TV, equipped with a refresh rate panel of 120 Hz, and in the appropriate PC configuration even 144 Hz, ensures excellent motion fluidity. Samsung focuses on a variety of image clarity settings on a ten-point scale, giving users the freedom to adjust the display to their own preferences. In UFO tests, the OLED panel shows its strengths, eliminating any blurring. The lightning-fast pixel response makes dynamic movements faithfully reproduced.

Similar results can be observed in other sizes of this model with a WOLED panel, which also offer excellent image fluidity. Organic technology, in this case, is considered one of the best on the market. The picture of Samsung S90D, regardless of the type of panel, is incredibly sharp and detailed, making this TV perfect for dynamic scenes, both during gaming and sports broadcasts. Additionally, its capabilities in terms of refresh rate and clarity ensure that every movement is smooth and natural, which will certainly satisfy even the most demanding users.

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.

Television S90D is an excellent solution for gamers, offering a range of advanced features that elevate the gaming experience to a new level. Equipped with the HDMI 2.1 standard, the model supports modern technologies such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Thanks to these solutions, the image is incredibly smooth, and the response to commands is instantaneous, which is crucial in dynamic titles. Additionally, the S90D supports HLG (Hybrid Log-Gamma) and G-Sync and FreeSync image synchronisation. This allows for a perfect connection with the Xbox, PlayStation, or PC, eliminating issues with tearing and stuttering. The built-in operating system offers the Xbox Game Pass app, providing access to a massive library of games directly from the television. This solution makes gaming even more convenient and accessible. The Game Bar feature provides quick access to important information, such as current settings, performance statistics, and the ability to adjust image options. This allows for on-the-fly modification of display parameters, which is incredibly useful during intense gameplay. Despite lacking support for Dolby Vision, Samsung S90D still delivers excellent HDR image quality, allowing for full utilisation of the potential of games and films. As a result, S90D represents a unique combination of modern technologies, excellent image quality, and intuitive features, perfect for any gaming enthusiast.

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.

QD-OLED from Samsung stands out with an incredibly low input lag, making it an excellent choice for gamers. Regardless of the resolution or refresh rate, both in SDR and HDR mode, results around 10 ms are truly impressive. Such a low input lag ensures immediate response to actions on the screen, which is crucial in dynamic games where every millisecond counts. Users can enjoy smoothness and precision, which makes the S90D TV with QD OLED panel a superb option for those who prioritise performance in gaming.

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.

The Samsung S90D 65 TV performs excellently as a monitor for PCs. Fonts appear sharp, making it easier to read and use various applications. Support for chroma 4:4:4 at a resolution of 4K and a refresh rate of 144 Hz ensures full colour reproduction and outstanding image clarity. Moreover, the impressive input lag of just 5 ms is a significant advantage, especially for gamers and professionals working with graphics. However, it should be noted that points were deducted in this category compared to the WOLED panel version due to the different diamond arrangement of sub-pixels, which may lead to the distinct visibility of individual sub-pixels when displaying fonts on a dark background. This issue only pertains to the 65-inch version, so users who plan to use the TV on their desk will not encounter these difficulties with smaller variants.

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.

In the category of viewing angles, the S90D Samsung stands out as one of the best models on the market. While traditional OLED TVs already offer solid performance, the use of a QD-OLED panel in the S90D elevates the picture quality to an even higher level. Thanks to the combination of Quantum Dot technology with self-emissive pixels, users can enjoy excellent color accuracy and detail, even when watching the TV from a wide angle.

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.

In the category of TV performance during the day, the model Samsung S90D 65 ranks the worst among the tested options. Although the glossy panel and good anti-reflective properties suggest some efficiency in bright conditions, the quality of blacks during sunny days proves to be the biggest issue. This phenomenon is caused by the close placement of quantum dots to the outer layer of the screen. Under the influence of external light rays, these dots can activate, resulting in the blacks on the screen becoming more cherry-like. This effect causes the image to lose depth and intensity, which can be particularly noticeable in darker scenes. As a result, users who plan to use the TV in bright rooms or under strong sunlight may encounter difficulties in achieving satisfactory image quality. However, when it comes to watching movies with a lot of black, this usually takes place in the evenings when the issue of intense sunlight is no longer as significant. In such conditions, the S90D performs significantly better, and users can enjoy a pleasant visual experience. During the day, while watching regular TV, the television also performs adequately, which means it is not a complete disqualifier for this model.

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 Samsung S90D television offers a range of features that significantly enhance user comfort, making it an ideal device for entertainment in the comfort of your home. The Tizen system, on which this model is based, is a modern and advanced platform that provides users with an intuitive and seamless experience. Thanks to the user-friendly interface, navigating through applications and settings is quick and intuitive, making it easy to use the television even for those less familiar with technology. Tizen supports a rich set of applications, including all popular streaming services such as Netflix, YouTube, and Amazon Prime Video. A new feature for 2024 is the availability of voice search in Polish. It is also worth noting the eco-friendly solar remote, which is not only environmentally friendly but also practical for everyday use. With it, you can control multiple devices connected to the television, eliminating the need for multiple remotes. Additionally, the television supports AirPlay, enabling easy content sharing from Apple devices such as iPhone or iPad. The S90D also allows for the connection of various Bluetooth devices like mice, keyboards, or headphones, which increases its versatility and allows for user experience personalisation. Furthermore, the SmartThings app significantly enhances the capabilities of the television, allowing integration with other smart home devices. This enables remote management of lighting, security, and other aspects of the home ecosystem. Users can also take advantage of the Philips Hue app, which allows for lighting synchronisation with the image displayed on the screen, creating even more immersive visual experiences. The only downside that can be pointed out is the lack of USB recording support. For some users, this may be a limitation. Despite this, the S90D television offers many advanced features and technologies that make it an excellent choice for anyone seeking high-quality entertainment in their home and wanting to integrate their devices into one convenient system.

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.

Samsung S90D is fitted with a built-in player that supports most popular video formats, allowing for convenient playback of films from various sources. The player also supports subtitles in Polish and allows users to customise the font colour, enhancing comfort when watching content with subtitles. In terms of photo formats, the television handles many, but one of the few downsides is the inability to play the popular PNG format. Nevertheless, the overall playback capabilities of the S90D are at an excellent level.

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 Samsung S90D TV is equipped with a 2.1 audio system boasting a total power of 40 W, delivering clear and dynamic sound. With a subwoofer located at the bottom of the casing, the bass is deep and palpable, while the mid and high tones remain well-balanced. It's worth noting that the twin model S94D offers an even more advanced 2.1.2 speaker setup with a power of 60 W. If the silver colour of the S94D casing is not a drawback, and the price difference between these models is minimal, it’s worth considering the version with the “4” at the end. Despite lacking support for the DTS format, the S90D TV utilises other advanced sound technologies such as Dolby Atmos and Dolby Digital Plus, providing spacious and immersive sound. It is also worth mentioning the presence of the proprietary Q-Symphony feature, which allows synchronisation of the TV's speakers with the manufacturer's soundbar.

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.
