Samsung OLED S90D / S94D (WRGB OLED) vs XIAOMI A PRO 2025

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

In the HDR category, the television Xiaomi A Pro is, to put it plainly, lacking. Under ideal conditions, it offers brightness at around 250 nits. This is a poor result; however, in this price range, many competing models offer similar or lower values. Such brightness is too low to fully realise the potential of HDR content. In practice, this means that the image does not gain the appropriate depth and intensity expected from high-quality HDR. These values are more characteristic of standard dynamic range (SDR), which means that the true HDR effect remains beyond the reach of this model, and scenes that should stand out with spectacular brightness and contrast seem flat and lacklustre. However, for its price, the television offers good coverage of the DCI-P3 colour gamut at 92%, thanks to the use of quantum dot technology (specifically PFS LED). This results in vibrant and saturated colours, which will appeal particularly to gamers and film enthusiasts who appreciate richer shades and better colour reproduction compared to traditional televisions without this technology.

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 a bit too warm, and users who switched from Standard mode may experience a slight shock. It is worth noting that this situation 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 exhibits drops in blue colour, making colours warmer than they should be. In practice, this means that some 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 graph indicates slight fluctuations, resulting in a minimally darker image, especially in shadows. This can affect less defined details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is above the recommended line, leading to overly bright displays in certain parts of the image, which can cause clipping in the brightest areas. Overall, Samsung S90D presents a solid picture right out of the box, but for the best effects, especially with more demanding content, additional calibration is recommended.

The Xiaomi A Pro 2025 television has been tested in movie mode, which offers the best colour reproduction straight out of the box. However, it is worth noting that it is not free from flaws. Analysing the white balance, it can be observed that the values for green are in the negative. This phenomenon leads to some distortions in the shades of white, and with pure white, the graph shows clear deviations. The over-contrasted image results in inappropriate tonal transitions in red, negatively affecting the quality of colour display. Generally, in the image below, it can be seen that the overall scenery before calibration acquires pink hues. Additionally, when analysing gamma contrast, the graph is significantly below the 2.4 value, suggesting that the television overly emphasises dark tones, and the brighter areas of the image may be less vivid. Furthermore, the EOTF curve shows a strong peak at the beginning, which can lead to a loss of detail in bright scenes and an unpleasant feeling of over-drawing. These aspects indicate a need for further calibration to achieve a more balanced colour reproduction and improve the overall image quality. Users who expect precise colour reproduction may be forced to take measures to adjust the television settings to achieve more realistic and natural visual results. In the xiaomi tv a pro 2025, the factory colour settings in Xiaomi are average and may require calibration. After proper colour adjustment, the image gains a natural and vibrant colour palette, much closer to cinematic standards. It is worth adding that the issue of inaccurate colour reproduction is typical for many televisions in this class, meaning it is not a flaw unique to the Xiaomi A Pro 2025 TV. For those who value perfect colour reproduction, professional calibration will prove to be a key element that enhances the overall image quality.

After calibration, the Samsung S90D television in movie mode looks even better than one might have expected. The white balance, for both HD and 4K HDR content, has been improved almost to perfection. Although minor flaws can still be noticed, they are minimal enough not to significantly affect the picture quality. The colours are more balanced, which translates to a natural reproduction of details, especially in scenes requiring 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 the 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.

Contrast has also seen significant improvement. The gamma graph post-calibration is much closer to the expected line, providing better balance between bright and dark areas of the image. The EOTF curve, which prior to calibration showed issues with overexposed scenes, now presents better results. This effect allows for greater detail retention in bright parts of the image, especially in HDR materials.

Now it's time to check how the Xiaomi A Pro 2025 television has performed after calibration. The biggest beneficiary of this process is the white balance. After the calibration was conducted, all previous errors were corrected in both HD and 4K content, and most errors no longer fall significantly outside the value of "2". This means a much more balanced and natural colour representation, which certainly affects the viewing comfort. In terms of gamma, the drop was significantly reduced, resulting in a more consistent tonal representation across various scenes. Nevertheless, the EOTF curve has not been significantly improved 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 may affect the perception of certain materials. However, despite these minor shortcomings, the overall shape of the image is definitely better after calibration. The television has gained in quality, and the improved white balance along with reduced gamma issues allows users to enjoy a more realistic and pleasant visual experience. Further adjustment of settings may enhance image quality even more, but even now the television demonstrates its capabilities, meeting the expectations of many users.

Television S90D performs very well at smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use noise reduction, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desirable film grain, which in turn could reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this feature, as it is better to leave the natural grain that adds character and authenticity to the viewed content.

Samsung, as always, does not disappoint and excels in the area of scaling images from lower resolutions. The S90D Samsung television effectively processes lower resolutions, as can be 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-rendered, showing no significant jaggedness, which could diminish the image quality. Thanks to effective scaling, even materials in lower resolution present attractively on the screen, pleasing users who prefer various sources of content such as regular antenna/cable television.

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

In the case of the tested image featuring a model and numerous branches in the background, the Xiaomi A Pro 2025 showcased its capabilities in terms of digital processing. Adding artificial sharpness to this scene made the details of the model more pronounced, and her hair appeared more detailed. However, delicate contours appeared around the branches in the background, which were a result of digital interference. Although this enhances the overall impression of detail, excessive sharpness can make some elements of the image seem unnaturally emphasised.

Samsung S90D TV is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, providing exceptional motion fluidity. Samsung has been offering a variety of sharpness settings on a ten-point scale for years, allowing users to adjust the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there's no sign of any smearing. 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 picture is extremely sharp and detailed, even during fast actions, making the S90D TV an ideal choice for gamers and sports enthusiasts.

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

The Samsung S90D TV is perfectly adapted to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). With these technologies, gamers can enjoy smoother and more responsive gameplay, significantly affecting 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 to parameters such as changing the TV's screen aspect ratio, which can be useful in various games and types of gameplay. Users can easily customise their preferences, making the use of the TV during gaming even more convenient and enjoyable. As for PC users, the TV pleasantly surprises. When connected to a computer, the panel is capable of achieving a refresh rate of 144Hz, and users of Nvidia or AMD graphics cards can enjoy features such as G-Sync and FreeSync. It should be noted, however, that the TV does not support Dolby Vision, which may be a drawback - but it's worth bearing in mind that Dolby Vision is not as popular for games as it is for films. Nevertheless, the S90D TV still offers excellent features for gamers, making it a great choice for gaming enthusiasts who seek top-notch picture quality and modern technological solutions.

Xiaomi A Pro 2025 offers several features useful for gamers, including Game Bar, which is different from the typical "dashboards" with interfaces found in other manufacturers' products. Thanks to this, users can quickly access game-related settings, which is convenient during intense sessions. The TV also supports Automatic Low Latency Mode (ALLM), meaning it automatically switches to a mode optimised for gaming, reducing signal latency. Unfortunately, it lacks support for HDMI 2.1, limiting its capabilities for connecting 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 visuals 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 solutions dedicated to gamers.
