Compare: Xiaomi S Mini 2025 vs Philips OLED811

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.

Philips OLED811 is a mid-range OLED for 2026 that stands out from its biggest rivals mainly for one thing: Ambilight. The light that follows the picture and spreads across the wall can change the mood of the whole viewing experience. In the evening the screen seems to extend beyond its frame and watching gains an extra bit of charm. For some it will be a pleasant extra, for others a decisive reason to pick Philips again. The picture itself is very comparable to what models like the LG C6 or Samsung S90H offer when using the same panel type. You get deep, perfect blacks that make bright elements really pop. The OLED811 can deliver strong HDR and, importantly, after calibration the picture is close to the reference. There’s no big advantage over the competition, but there’s also no sense that by choosing Philips for Ambilight you’re sacrificing image quality.

Gamers also get a few solid upgrades over last year’s model. Thanks to the MediaTek Pentonic 800 chipset we finally have four HDMI 2.1 ports, so connecting several devices, for example consoles, a PC and a soundbar, no longer means you have to decide which one gets the full capabilities of the port. Gaming itself is very enjoyable — the TV responds quickly, supports variable refresh rate, and from a PC it allows gaming in 4K at 165 Hz. It’s a pity the new processor’s capabilities haven’t been put to equally good use when processing lower-quality sources. The biggest doubts, however, concern the operating system. Titan OS replaced the popular Google TV and, although it has clearly developed over the past year, it’s still hard to call the change a good one. True, the system runs more smoothly, has more useful features, and its library already includes most popular streaming services. Still, the choice of apps is much smaller than Google’s (or the competition’s), and in our view that remains the OLED811’s biggest drawback. People using less popular services may feel that difference particularly strongly.

Is it worth buying? Yes, if Titan OS meets your needs. In terms of picture and the gaming features, the OLED811 has as much to offer as its rivals, but Ambilight gives it something others don’t. Philips therefore gives and takes a bit. It adds a unique viewing atmosphere but limits freedom of app choice. If the services you use are available, this compromise may be worth accepting.

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.

Black levels and contrast are categories where the Philips OLED811 showcases all the advantages of OLED technology. Each pixel emits light independently and can be switched off completely, so black is simply black. No grey halo or blooming around bright objects. During evening viewings this creates a striking effect: stars in the night sky, city lights or text on a dark background remain clearly separated from a perfectly black surround.

So it's hard to expect any improvement over other OLEDs here, because in terms of black depth and contrast the result is already exemplary. The OLED811 doesn't need local dimming zones or a compromise between the brightness of a small object and the black around it. Even a single bright point can sit next to a completely switched-off pixel, giving the image excellent depth.

It's precisely in scenes with a lot of black that the advantage over Mini-LED TVs becomes apparent. Even the most advanced local dimming systems control larger areas of the picture, so in demanding shots they can produce a halo around bright elements or dim them to preserve the dark background. The Philips OLED811 doesn't have that problem.

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.

Philips OLED811 uses the new generation WOLED EX panels, also found in models like the LG C6 and Samsung S90H. After calibration we measured about 1500 nits, which is a very good result for an OLED TV. You can see that clearly in films and series. Flashes of light have the right punch, especially when they appear on a dark background. In those scenes the OLED811 can deliver really impressive HDR. Of course this doesn't mean you'll see that level of brightness in every shot. When the screen is filled with a large area of white or a wide explosion, brightness falls to around 600 nits. That's still a good result, but such scenes don't have the same impact as small bright elements on a dark background. That's a known limitation of OLEDs and the OLED811 is no exception.

Colours

Aside from HDR brightness, colours also matter and here Philips also performs very well. It covers almost the entire DCI-P3 gamut, which contains most of the colours used in HDR films and series. So you get rich reds and lush greens, and while watching it's hard to fault it in that regard. It looks a bit worse with the much wider BT.2020 gamut — its most saturated shades are already beyond the reach of this panel. There's also the issue of the white subpixel that the WOLED panel uses to help boost brightness. With very bright colours you can see a certain "washout": the colour is bright but loses some of its intensity. It's in exactly these situations that Samsung Display's QD-OLED panels have the advantage. In most films and series, though, this won't be something that immediately jumps out at you.

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.

The film mode on the Philips OLED811 is sensibly set up straight out of the box. Most colour errors remain minor in both SDR and HDR, so you can comfortably sit down to watch without adjusting the settings first. There are no large inaccuracies that would immediately distract from the film.

It’s not quite perfect, though. The white balance shows a slight lack of red relative to green, so whites and greys can have a faint greenish tint. It’s not a strong colour cast, but measurements clearly show it. There are also small luminance deviations in SDR: some parts of the image are slightly brightened, and the deepest tones aren’t always reproduced evenly. In HDR the TV stays much closer to the reference, although it occasionally lifts detail from the shadows. These are generally things that can be refined. The factory film mode provides a good starting point, and calibration will reveal how much more you can get out of it.

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.

After calibration the Philips OLED811 delivers an image very close to the reference. We managed to even out the white balance and remove the slight colour cast visible in the factory settings. ColorChecker errors for SDR and HDR fell to around 1 to 2, with many samples even below 1. That's a level at which differences from the reference are hard to spot with the naked eye. We also improved the gamma, with only a slight lift remaining in the brightest whites. In HDR the EOTF curve also stays close to the reference, although the TV still tends to slightly boost the brightness of small details, such as stars or subtitles. That gives the picture a bit of extra brightness that shouldn't be there, but otherwise it's hard to find fault. It was already good out of the box, and calibration allowed us to iron out most of the remaining issues.

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.

Compared with Philips' previous OLEDs, the smoothness of tonal transitions has clearly improved. The biggest difference is in the dark parts of the picture, which can cause WOLED panels quite a few problems. On the OLED811 they have been smoothed very well, with tones flowing smoothly from one to the next, without obvious banding or posterisation. That's a big plus, especially when watching dark scenes.

Unfortunately, it isn't as good in brighter shots. That's where we have the biggest reservations: instead of a gentle transition between tones you can sometimes see distinct boundaries, in other words posterisation. It can be noticeable, and it's a pity the improvement seen in dark scenes didn't extend to the brighter areas of the picture to the same degree.

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 OLED811 handles processing lower-quality material reasonably well, though it's far from perfect. The "Banding reduction" function helps smooth tonal transitions and on the low setting gives a pretty good effect. It doesn't remove banding between shades as effectively as similar solutions from some competitors, but at least it doesn't introduce new artefacts. It's a sensible setting for everyday viewing. Still, there's a bit of a letdown, because the MediaTek Pentonic 800 chipset used here can, in other manufacturers' hands, deal with the effects of heavy compression more effectively even at similarly low settings. A lot therefore depends on how a given manufacturer uses its capabilities.

We have a few more comments about the upscaling to 4K. There's plenty of detail, but overall the image looks rather soft. Edges are heavily smoothed, so the picture lacks some sharpness and clarity. You can partially correct this with the sharpness slider in the menu, though that will be extra edge enhancement rather than recovering detail. On the plus side, there's no overscan, and even with an SD signal the TV doesn't crop the edges of the picture.

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.

In terms of motion handling the OLED811 performs superbly. At 120 Hz, which is useful for console gaming and watching sport, the image remains clear and moving objects don't leave noticeable trails. The OLED's fast pixel response helps here. You can see it clearly in the UFO test, even on a dark background. There are also controls for motion smoothing. In movies you can adjust the strength of smoothing to your taste, from preserving a cinematic feel to much smoother motion. A separate blur-reduction control is useful for fast-paced content like live sports broadcasts.

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 OLED811 has almost everything you’d expect from a TV for gaming. It supports 120 Hz at Full HD, 1440p and 4K, and when connected to a PC it can reach up to 165 Hz. It also offers VRR to help avoid screen tearing when frame rates fluctuate, and ALLM, which automatically switches to game mode. So you don’t have to go into the settings every time you start your console.

Another plus is the properly working HGiG, which ensures that once HDR is set on the console the TV doesn’t apply its own changes to image brightness. The Game Bar is also available, letting you check signal parameters and quickly change settings useful while gaming. The list even includes Dolby Vision for games, but there’s a significant catch here, which you’ll read about below.

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.

OLED811 responds instantly. We measured 14 ms at 60 Hz and just 5 ms at 120 Hz, both in Full HD and 4K. Those are excellent results that let you comfortably play even fast online multiplayer games. Unfortunately, when Dolby Vision is enabled the situation changes dramatically: at 60 Hz latency rises to 157 ms, and at 120 Hz it’s 57 ms. The first result in particular already causes a clearly noticeable lag between a movement on the controller and the response on screen. For gaming it’s definitely better to stick with HDR10.

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 Philips OLED811 works very well with a PC. The manufacturer has finally managed to correctly implement 4:4:4 chroma, even at maximum resolution and refresh rate. As a result, small text and coloured edges are readable, without the blurring or rainbow fringing that comes from loss of colour information. Dark text on dark backgrounds also holds up well, which TVs can struggle with. There are still minor imperfections related to the RGWB subpixel layout. Fonts are not as sharp as on a classic RGB monitor, and with white letters you can see faint red halos up close. From a normal viewing distance you barely notice it, though it’s easier to spot when sitting close at a desk.

Where it really shines is gaming from a PC. The combination of 4K at 165 Hz, working G-Sync and input lag around 5 ms makes the OLED811 excellent for that. If you have a computer that can take advantage of that refresh rate, it’s definitely worth plugging it into the Philips.

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.

The viewing angles on the OLED811 are excellent and among the best on the market. Even when sitting well off to the side you still see an image with deep blacks and well-saturated colours. That's a big advantage over LCD screens. You don't have to sit exactly in front to enjoy good picture quality.

QD-OLED panels perform even better, keeping colours more faithful at off-axis angles. On the Philips, at wider off-axis angles the whites shift slightly towards greenish tones, but the effect is so small that it's hard to find it bothersome while watching. We'd even say that in this respect this is the best WOLED panel sample we've tested so far.

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.

OLED811 copes with daytime viewing, although in a very bright living room it already has its limits. Peak brightness in SDR reaches about 600 nits, a level comparable with the LG C6 or Samsung S90H, which use the same panel. That’s noticeably more than basic OLEDs and will be plenty for most people. Bear in mind, though, that this brightness isn’t maintained across the whole screen — it falls with a lot of white, and the average from our measurements was around 392 nits.

A bigger issue can be direct reflections from windows or lamps. The glossy coating dampens them reasonably well, but they’re still clearly visible on the screen, especially in dark scenes. It doesn’t diffuse reflections as effectively as matte screens, so placing the TV opposite a large window isn’t the best idea. On the plus side, black levels remain very good even in daylight. In a typical living room the Philips will therefore perform without major problems, but with strong sunlight falling directly on the screen you’ll want blinds.

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.

Smart features — Titan OS

The Smart TV system is the most controversial change in the OLED811. Philips has dropped the user-favourite Google TV in favour of its own Titan OS. For many people this may be a hard decision to accept, although Titan is getting noticeably better year on year and runs more smoothly. We have working AirPlay, screen mirroring from a computer and voice search in Polish. System responsiveness has improved too, though you can still notice small delays when navigating the menus. We have the impression the IR remote is partly to blame, as it doesn’t always pick up commands immediately. The biggest limitation compared with Google TV is the smaller selection of apps. That doesn’t mean it’s empty, however — you’ll find Netflix, Prime Video, Disney+, CANAL+, and Apple TV has recently joined the library. If you mainly use popular services, Titan should be fine, but it’s worth checking availability of less well-known apps before buying (see the list at the bottom 😉).

Ambilight

Ambilight remains one of the best reasons to consider a Philips TV. On the OLED811 it’s three-sided — LEDs along the top and sides of the casing light the wall with colours matched to what’s happening on screen. In the evening this creates a great effect and can change the whole room’s atmosphere, so we awarded extra points for this feature. You don’t have to use the dynamic picture tracking though. If you prefer a calmer viewing environment you can set a static white light. It’s a pleasant option for evening sessions when you don’t want to sit in front of a bright screen in a completely dark room.

Classic features

For regular TV viewing the OLED811 performs well, though it lacks USB recording and picture-in-picture (PiP). You can connect Bluetooth headphones and use them alongside the TV’s speakers. What bothers us most, however, is the infrared control mentioned earlier. The remote itself is quite interestingly designed: it’s backlit and has a hybrid keyboard with a numeric section. It’s a shame you still have to point it at the TV like with old sets. With equipment at this level we’d prefer to just press buttons without worrying which way we’re holding the remote. Hopefully Philips will fix that in future models.

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 USB player in the OLED811 handles most of the audio and video formats we test, so it's perfectly adequate for watching a movie or playing music from a USB stick. Our main reservations are about photos, specifically the strangely selective handling of their resolutions. The TV opened 8, 16 and 32 Mpix files, but couldn't cope with the rest. So it's not that the photos are simply too large, because the player can display a higher-resolution image and refuse to open a smaller one. When browsing holiday photos this can be genuinely annoying, as some will need to be converted on a computer first... or you could just use remote screen mirroring...😉

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.

There have been a few concrete changes to the sound compared with last year’s OLED820. The rear subwoofer is gone and the 4.1 speaker layout has been replaced by a 2.2 configuration. Despite these changes the OLED811 still sounds good and fairly even. It can play louder, and the sound even seems a touch fuller than a year ago. The bass has suffered; although the sound has weight, the low end lacks the depth of its predecessor. You can hear this most clearly in films and music when you’re waiting for a stronger hit. That said, it’s still well above average for built-in TV speakers. If you want deeper bass and more distinct spatial effects, it’s worth considering a soundbar or a system with an AV receiver. Philips gives you plenty of flexibility: it supports both Dolby Atmos and DTS, and will pass Dolby TrueHD tracks over HDMI eARC to compatible equipment without any problems. So there’s room to upgrade later if you decide to expand the sound system.
