Our verdict

The SAMSUNG S90D, also known as the S94D, is equipment that repeatedly surprised us positively during our tests. It’s worth mentioning at the outset that depending on the selected size, differences may concern the applied OLED panel. However, regardless of which variant we encounter, one can count on excellent blacks and HDR effects that, thanks to high brightness, make a huge impression. This is one of those TVs that can truly elevate home viewing to a cinematic level. During testing of films and series, we immediately noticed the great colour reproduction and depth of blacks. Dark scenes, which can be problematic on other screens, are full of details and immersive here. Although the factory colour settings could be a bit better, after calibration, the image gained clarity, and the TV showed what it’s really capable of. In terms of everyday usage, we noted that the wide viewing angles allow comfortable watching of content even from less central positions. The Tizen operating system appealed to us – it’s clear, fast, and offers access to the most popular apps. AirPlay works seamlessly, which was a nice addition during testing. And what about image smoothness?... The 144 Hz panel performs excellently. While watching sports, the image was smooth, without the slightest blur. Matches or races felt like we were really in the stands. We also couldn’t skip gaming tests. Low input lag and support for HDMI 2.1 make the S90D/S94D a great choice for gamers. Games ran smoothly, and every movement was displayed with incredible precision. This is equipment that meets the expectations of even the more demanding console users. The SAMSUNG S90D/S94D is a TV that combines excellent picture quality with modern features and versatility. Regardless of whether we're watching films, playing on a console, or simply using apps, this model impresses. In its price range, it’s truly a strong contender.

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.

Halo effect and black detail visibility:

Samsung S90D, thanks to its OLED matrix, offers infinite contrast, which is one of its greatest advantages. OLED matrices are characterised by each pixel emitting its own light, allowing for deep blacks and excellent detail reproduction in dark scenes. In contrast to traditional LCD matrices with backlighting, where black often takes on a grey hue due to uneven backlighting, OLED guarantees that switched-off pixels remain completely black. This allows for a very high level of contrast, making images more dynamic and realistic. In the scene from "Oblivion", the Samsung S90D beautifully showcases the high light effect of the lantern, highlighting the intensity and details in the bright parts of the image. Meanwhile, in the film "Sicario 2", you can perfectly see the separation of the helicopter lights from the dark background. A surprising aspect of the S90D model is the fact that Samsung, after years of disputes, decided to use organic matrices produced by LG, in versions with "DAE" endings in their names. Is that a bad thing? No! In terms of contrast, both WOLED and QD-OLED matrices offer the same, which is perfect black.

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.

Samsung OLED S90D / S94D (WRGB OLED)

In the tested film scenes, the Samsung S90D television achieves impressive brightness results, exceeding the 1000 nit barrier in the first four shots, which can be considered a remarkable outcome. In the case of the last shot, where a full-screen flash of sunlight is visible, the brightness drops to around 500 nit, but it still remains at a very good level. Additionally, the television impresses with a DCI-P3 colour space coverage value of 98%, which guarantees extraordinarily rich and realistic colour reproduction, further enhancing the image quality. This result makes the Samsung S90D an ideal choice for those expecting high-quality images in a variety of lighting conditions.

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.

After calibration

Factory Mode

After calibration

The S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more discerning users. This mode may seem too warm, and users who have switched from Standard mode might experience a slight shock. It’s worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to appear warmer than they should. In practice, this means that certain shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates slight fluctuations, which may result in the image being minimally darker, especially in the shadows. This can affect the clarity of details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is located above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, Samsung S90D delivers a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

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.

Color reproduction after calibration

8.7/10

8.4/10

After calibration, the Samsung S90D TV in movie mode looks even better than one might expect. The white balance for both HD and 4K HDR content has been improved almost to perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, leading to a natural reproduction of details, especially in scenes that require a precise colour palette. It is worth noting that this model in this size is equipped with a WOLED panel, which has less coverage of a wide colour gamut and does not offer as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

The contrast has also seen a significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between bright and dark areas of the image. The EOTF curve, which showed problems with overexposed scenes before calibration, now demonstrates better results. This effect allows for greater detail to be preserved in the bright parts 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.

Smoothness of tonal transitions

7.6/10

8/10

The fluidity of tonal transitions in the Samsung S90D television is at a good level, although subtle imperfections are noticeable in places. In most scenes, the tonal transitions are fluid and well-reproduced, providing a natural viewing experience. In more demanding sequences, such as a dark coloured sky, slight issues may arise; however, they do not significantly affect the overall visual experience. In the test scene with dominant red hues, slight cutoffs in the brighter areas can be observed, but they are subtle enough not to disrupt viewing. Overall, the fluidity of tonal transitions in the Samsung S90D television is solid, ensuring a good reception of content.

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.

Television S90D handles tonal transitions very well. Thanks to the technology used, transitions between colours are smoother and more natural. You can also use the noise reduction feature, which further smooths out tonal transitions, which can be useful in certain situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing out of desirable film grain, thereby reducing the cinematic feel of the image. For this reason, caution is advised when using this feature, as it’s better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels in scaling images from lower resolutions. The S90D Samsung TV effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and accurate and, as a result, looks natural and detailed. Moreover, the branches of the trees are well-represented, showing no significant jaggedness that could degrade image quality. With effective scaling, even materials in lower resolution present attractively on the screen, satisfying users who prefer various sources of content such as regular antenna/cable 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 is equipped with a 120 Hz panel, with the ability to overclock to 144 Hz with the right PC configuration, providing exceptional motion smoothness. For years, Samsung has offered a variety of ten-point settings for image clarity, allowing users to adjust the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any motion blur. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D an ideal choice for gamers and sports enthusiasts.

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.

With these technologies, gamers can enjoy smoother and more responsive gameplay, significantly enhancing comfort and performance during intense gaming sessions. An additional advantage of the television is the special Game Bar, which allows for easy management of game settings. This functionality enables quick adjustments of parameters, such as changing the aspect ratio of the television screen, which can be useful in various games and types of gameplay. Users can easily customise their preferences, making the use of the television while gaming even more convenient and enjoyable. As for PC users, the television pleasantly surprises. When connecting a computer, the panel is able to achieve a refresh rate of 144Hz, and users of Nvidia or AMD graphics cards can enjoy features such as G-Sync and FreeSync. However, it should be noted that the television does not support Dolby Vision, which may be a downside – although it is worth considering that Dolby Vision is not as popular in the context of games as it is in films. Nevertheless, the S90D television still offers excellent features for gamers, making it a great choice for gaming enthusiasts looking for outstanding picture quality and modern technological solutions.

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.

Viewing angles on the Samsung S90D television, thanks to OLED technology, are unmatched. OLED offers excellent colour and contrast reproduction, even at wide viewing angles, which ensures the picture remains clear and vibrant from almost any perspective. Users can enjoy a consistent visual experience, regardless of where they are watching the screen from. The only televisions that might perform better in this regard are models equipped with MLA (Micro Lens Array) or QD-OLED technology. These innovative solutions further enhance picture quality from various angles, but under standard conditions, OLED remains the leader in viewing angles, providing users with exceptional visual experiences.

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.

When watching during the day, the Samsung S90D performs very well, achieving an average brightness of around 400 nits, which is a very good result for OLED technology. Despite the use of a glossy panel, glare suppression is at a decent level, allowing for comfortable viewing even in bright rooms. The only noticeable downside of this technology, rather than the television itself, is the brightness at 100% white screen fill. In such conditions, OLED may struggle to achieve extremely high brightness. Situations like this can be seen when we want to watch winter sports, such as ski jumping.

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 S90 television offers a range of features that significantly enhance user comfort and make 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 smooth experience. Thanks to its user-friendly interface, navigation through applications and settings is quick and intuitive, making it easy for even those who are less tech-savvy to use the television. 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. For example, the remote can control multiple devices connected to the television, meaning we do not need to use multiple remotes. Additionally, the television supports AirPlay, allowing for easy content sharing from Apple devices such as iPhone or iPad. The S90D Samsung also allows for the connection of various Bluetooth devices such as mice, keyboards, or headphones, which increases its versatility and allows for the personalisation of user experiences. This way, users can easily adjust their settings to make the most of the television's capabilities. The only downside that can be pointed out is the lack of USB recording support. For some users, this may be a limitation, especially when it comes to archiving favourite shows or movies. Despite this, the Samsung S90D television offers many advanced features and technologies that make it an excellent choice for anyone looking for high-quality entertainment in their home.

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 equipped with a built-in media player that supports most popular video formats, allowing for convenient playback of films from various sources. The player also supports subtitles in Polish and enables users to customise the font colour, increasing comfort while watching content with subtitles. In terms of image formats, the TV handles many of them, but one of the few downsides is the lack of ability 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 with a total power of 40 W, providing clear and dynamic sound. Thanks to the subwoofer located at the bottom of the casing, the bass is deep and palpable, while the mid and high tones remain well-balanced. It is worth noting that the twin model S94D offers an even more advanced 2.1.2 speaker set with a power of 60 W. If the silver colour of the S94D casing is not an obstacle, and the price difference between these models is minimal, it’s worth considering choosing the version with the digit “4” at the end. Although the TV does not support DTS format, it offers other sound technologies such as Dolby Atmos and Dolby Digital Plus. However, to fully enjoy surround sound, it’s worth considering connecting an external audio system.

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.
