Philips PUS8359 (IPS) vs Xiaomi S Mini 2025

The quality of HDR effect on the Philips PUS8359/12 television is also not impressive. A brightness level of 280 nits is too low, resembling standard SDR more than true HDR, which is clearly visible on the five tested images. Additionally, the television does not impress in terms of color gamut coverage – just 76% DCI-P3 is a result that can be considered weak, especially compared to other models in a similar price range.

Since the Xiaomi S MiniLED boasts an impressive number of 308 dimming zones, it was 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. However, do these numbers translate into real experiences in movie scenes? In the case of less demanding shots, like those from the film The Meg, the television indeed showed excellent results, reaching up to 900 nits. Such values are impressive and can truly convey the strength of HDR effects.

Unfortunately, similar to the contrast situation, there were issues. When smaller, brighter elements appear on the screen – as in challenging scenes from Sicario 2 – the aggressive operation of the dimming zones spoils the whole effect. Brightness during these moments drops to just 100 nits. This is definitely too little to capture the full magic of HDR. Instead of a dynamic and detailed image, the viewer gets a muted, almost flat impression, which diminishes the enjoyment of the viewing experience.

In summary, if we are 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 dimming zones means that watching movies in the evening, especially in demanding HDR scenes, can be more frustrating than satisfying.

The "Film" mode turned out to be the most faithful in terms of compliance with the source material used in our tests. However, like other factory modes, it also had its drawbacks. In both SDR and HDR materials, we noticed issues with white balance, where the dominance of green and red resulted in a yellowish tint. This effect was particularly visible in the form of yellowed whites and unnatural skin tones. The "ColourChecker" palette test showed that every color was shifted towards warmer tones, which affected color accuracy. A key aspect of the image is also contrast and brightness, which can be evaluated by analyzing gamma charts and the EOTF curve. On the gamma chart, we observed significant deviations – both too high values causing loss of detail in the shadows and too low values leading to a drastic decrease in contrast. Compared to gamma, the EOTF curve performed better, only slightly brightening the image, which had a less negative impact on overall quality.

Xiaomi, like many manufacturers, offers a wide range of picture modes. On the S MiniLED, we can find both IMAX Enhanced and Filmmaker. We conducted our tests in Filmmaker mode, which theoretically is supposed to reference the original image, but the reality turned out to be somewhat different.

Let's start with the test of SDR materials. Here, the television had quite a few problems, especially with white balance. The clearly visible dominance of red made the image appear too warm, and all colors gained a reddish tint. This was particularly noticeable in a comparative scene from the Star Wars movie. The brightness characteristics (gamma) also left much to be desired – instead of a smooth transition, we had a real "rollercoaster," with a visible excessive brightening of the screen.

In 4K materials, the situation looked much better. The white balance, while still not perfect, was much more balanced, with a slight dominance of red and blue, but without excessive influence 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, for example, in the test scene from the Pan movie that we described above. These brightening effects can disrupt image precision, but in 4K, the overall effect was much more acceptable than in SDR.

Although the Xiaomi S MiniLED can positively surprise in 4K materials, its factory settings in SDR require significant adjustments, especially in terms of white balance and brightness. It is definitely a television that would benefit from calibration.

Philips, both in its cheaper and more expensive models, offers a wide range of tools for image calibration. We used them to improve the quality of the displayed image, although it was not as simple as it might seem. We managed to adjust the white balance, improve the gamma, and tune the EOTF curve; however, despite these actions, the deltaE errors were still at a very high level. The main causes are limited coverage of the DCI-P3 color palette and low maximum brightness, which significantly affected the final result. Although the overall presentation looks much better, the design features of the TV did not allow us to achieve spectacular results.

Xiaomi S MiniLED 2025 is a television that gains a whole new life after calibration. The results are truly remarkable and show how much potential this model has.

In SDR mode, the white balance is nearly perfectly aligned. The errors are minimal enough that in many cases they can be considered negligible. This is confirmed by the Colour Checker palette results, where the errors did not exceed 2 ΔE – a result that is indeed quite rare. Gamma also looks very good, although at the beginning of the graph, there are slight brightenings in the darkest elements. However, this is a minor exception that does not significantly affect the image perception.

In 4K HDR materials, calibration also brought visible improvements, especially in white balance. The image looks natural and consistent. However, the brightness characteristic remains a problem. EOTF analysis in film materials shows that the television tends to over-brighten or darken the smallest elements on the screen. This is a result of limitations in the dimming algorithms that we previously discussed concerning HDR and contrast testing. Unfortunately, this is a technical feature of this model that cannot be completely eliminated.

Despite this minor flaw, calibration allowed extracting the maximum capabilities from this television. The image now looks phenomenal, and its quality impresses with every type of material. Xiaomi S MiniLED 2025 demonstrates that with the right settings, it can compete with more expensive models.

In this paragraph, we will look at two functionalities. We will once again take a look at the function responsible for tonal transitions, but we will also check how the television handles image scaling. The option responsible for smooth gradation is the one called "Distortion Reduction." As we established, it quite effectively smooths out the choppiness. However, we must point out two things: we cannot enable it for HDR materials and that it blurs details in films. The tested television cannot boast the best image scaling. There is a noticeable overall blurriness of the image, but, worse, it blurs details. This is particularly visible on the branches and the hair of the model. A characteristic white halo around the character is also noticeable.

When it comes to color transitions in lower quality materials like YouTube or television, the Xiaomi S MiniLED is equipped with the "Color Contour Removal" feature. In the "low" setting, it works quite well, but its effectiveness can be uneven. Sometimes it seems like the TV struggles with smoothing, which creates a certain dissonance. On the plus side, we did not notice any visible side effects, although given the instability of this feature, one might suspect that unexpected issues could arise in some situations.

Image scaling also performs average. There is slight aliasing, especially on thin elements like branches, and subtitles can appear a bit jagged. While it may not be very bothersome, a more discerning eye will certainly catch these shortcomings. 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.

Philips PUS8359 is not the best choice for watching sports. The lack of even basic motion enhancement features means that the picture in dynamic scenes is not suitably clear. Despite using an IPS panel (43 and 55'), which theoretically should offer better sharpness than VA panel variants, there is no noticeable improvement in terms of motion blur. In fast-moving images, it is clear that the UFO character is distinctly blurred, which indicates that the television does not cope well with maintaining sharpness in dynamic shots.

Xiaomi S MiniLED 2025 is equipped with a display that refreshes at 4K@120Hz (1080p@240Hz), providing sufficient smoothness for both watching dynamic sports broadcasts and playing the latest games. This level of refresh rate makes the image look smooth, even in the most intense scenes. Additionally, the TV offers a "Motion Smoothing" feature that allows users to adjust the way images are displayed in movies. We can choose a more frame-like effect, typical of cinematic experiences, or a smoother one reminiscent of the so-called "theatrical effect." This way, every user can tailor the settings to their preferences and enjoy smooth images in their favorite content.

In terms of compatibility with consoles, the Philips PUS8359 is mainly suitable for casual gamers. Although the TV is equipped with an HDMI 2.0 port, it offers features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and Game Bar. ALLM automatically switches the TV to low latency mode, facilitating quicker reactions during gameplay, while VRR smoothly adjusts the refresh rate, eliminating the issue of screen tearing. Game Bar provides quick access to game settings and real-time monitoring of parameters; however, in our opinion, it performs worse compared to competitors' solutions.

However, more demanding gamers may feel underwhelmed. The Philips PUS8359 does not support advanced HDR formats in games or higher refresh rates, which is due to the use of a 60 Hz panel. These shortcomings limit the TV's capabilities in delivering smooth and detailed experiences during fast-paced, dynamic gameplay.

Xiaomi S MiniLED 2025 is a television that has a lot to offer gamers. With two HDMI ports with 48 Gbps bandwidth, we can easily connect modern consoles or PCs, utilizing their full potential. Additionally, the ALLM feature automatically switches the television to low latency mode – something we will appreciate during dynamic games without annoying lags. No matter what we connect, it works smoothly, and the television handles various resolutions well. There is also GameBar, which may not look as impressive as the "bars" from the competition, but makes up for it with practicality. It's a simple settings panel that allows us to quickly change the most important options or check statistics – an ideal solution when time is of the essence.

However, we have to admit that operating the television itself – or rather finding the gaming features – was quite a challenge for us. We approached the Xiaomi S MiniLED 2025 test several times to find all the necessary options. The hidden menu allowed us to discover the "GameBoost" feature, which enables switching the television to 240 Hz mode, activating VRR at 120Hz, and turning on the image in HGIG mode.

In summary, the Xiaomi S MiniLED 2025 is a television that definitely deserves praise in the gaming hardware category. Its rich set of features – 240 Hz mode, VRR, HGIG, and "GameBoost" – provides exceptional gaming experiences. Unfortunately, the intuitiveness of the menu itself leaves much to be desired and may pose a certain challenge for the average user.
