XIAOMI A PRO 2025 vs Samsung S90H (WOLED)

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

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although it is slightly dimmer compared with the QD-OLED version. That difference is not as pronounced as in last year’s F series, where gaps sometimes reached 500 nits. Here the parameters of both panels are very similar, with differences in peak brightness of only about 100–150 nits. In small-window measurements the S90H with the WOLED panel easily reaches close to 1,500 nits. That headroom lets it phenomenally convey the dynamics of HDR effects — blooms, light reflections and explosions have the right punch, exactly as intended by the studio creators. As with most OLED displays, when a very bright scene fills the entire screen, panel protection systems kick in and brightness naturally falls to around 700 nits. It’s worth stressing that this is still an excellent result on the market, often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, very high-brightness colours don’t achieve quite the same saturation, and the wide-colour volume is slightly more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches almost 99%, meaning that for the vast majority of real film scenes both variants will present an almost identical image. The real gap only appears in rarer, especially demanding productions that use the ultra-wide BT.2020 gamut. Because of the WOLED panel’s construction, coverage of that standard is roughly 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit HDR colours may appear a touch less vivid.

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

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the annoying oversaturation seen in more aggressive profiles. However, as is often the case without full calibration, there is unit-to-unit variation. In our test the white balance was a little deficient in the blue component, so the image leaned slightly towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at around 2.2, which caused a small lift in shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

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

After full calibration, you can safely say the S90H in the WOLED version looks almost perfect. In SDR mode colour errors fall to ultra-low levels and Delta E values very rarely exceed 2. That's a phenomenal result, so if perfectly faithful colour reproduction matters to you, it's definitely worth getting it calibrated. The calibrated HDR mode also performs very well, where the white balance was stabilised and previous deviations eliminated. After professional tuning it's really hard to fault anything, because the TV delivers an image with almost exemplary naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the saturation limitation in extremely bright scenes, while the tuning potential and colour fidelity are at the highest level.

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

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

When it comes to banding reduction itself, Samsung has kept the same solutions known from last year’s models. The dedicated gradient-smoothing function works quite well and can effectively mask unwanted tonal transitions, which can be useful on a WOLED panel that’s somewhat more prone to banding. However, it’s important to remember it acts aggressively. This mechanism, aside from the artefacts themselves, can remove fine film grain and subtly soften detail. Ultimately it’s a trade-off, but if you want perfectly faithful image reproduction, it’s safer to leave this option off.

There’s also no breakthrough in scaling. The S90H uses the same NQ4 Gen3 processor as its predecessor, so upscaling quality was almost identical. The chip sharpens lower-resolution material very well, pulling a satisfying level of detail out of it. However, Samsung still hasn’t solved the old overscan problem. For some older recordings or archival footage the edges of the image can be slightly cropped. It’s a minor drawback, but it’s a shame the manufacturer still hasn’t fixed it.

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

When it comes to motion handling the S90H is simply excellent. This year's panel offers its refresh rate boosted to 165 Hz, although in practice the benefit will mainly be for gamers connecting a powerful PC. For movies, TV series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, the OLED panel's lightning-fast response time does the job. Motion is clean, and the ghosting or smearing seen on LCDs simply doesn't occur here.

Xiaomi A Pro 2025 offers several features useful for gamers, including Game Bar, which differs from the typical “dashboards” with interfaces found in other manufacturers. With this, users can quickly access game-related settings, which is convenient during intense gaming sessions. The TV also supports automatic low-latency mode (ALLM), meaning it automatically switches to a mode optimised for gaming, reducing signal delay. Unfortunately, it lacks support for HDMI 2.1, limiting the connection capabilities for the latest gaming consoles that may require higher bandwidth. Additionally, the TV does not support features such as VRR (variable refresh rate) or G-Sync, which are increasingly desired by gamers as they allow for smoother images and eliminate tearing. For these reasons, although Xiaomi A Pro 2025 has some features for gamers, in this price range, better options can be found that offer more advanced gaming solutions.

Gamers should feel right at home with the S90H, because Samsung has left few reasons to complain in this area. The TV has four HDMI 2.1 ports, each supporting VRR, ALLM and high refresh rates. There's also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG. In last year's models it could cause issues when used with a console, but on the S90H it now works as it should. What really stands out against the competition is Game Motion Plus. It's a specialised motion-smoothing mode for games that works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother and latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That's important, because on many TVs enabling a similar smoothing feature causes such a big increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There's still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be the more useful feature.
