Samsung DU7192 (IPS) vs Xiaomi S Mini 2025

The maximum luminance for HDR content on the Samsung DU7192 is 245 nits, but is often exceeded by even lower results. Such values are insufficient for comfortable viewing of HDR material due to the lack of appropriate image dynamics and the colour distortions caused by the device's low brightness. While the manufacturer has equipped the device with an HDR format featuring dynamic metadata, specifically HDR10+, it is rarely used compared to Dolby Vision, which Samsung has yet to introduce in its televisions. It is also worth noting that the Samsung DU7192 only covers 82% of the wide colour gamut DCI-P3, meaning that sending signals in a wide dynamic range should be avoided, as significant colour loss will be evident.

Overall, the Samsung DU7192 delivers high-quality images that will satisfy most users. The television stands out particularly for its vivid colours and decent contrast. Thanks to UHD technology, the image on the screen is sharp and clear, even during fast-moving scenes. The DU7192 also supports HDR, allowing for better reproduction of details in bright and dark areas of the image.

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 best factory mode we used throughout the testing process was "Filmmaker." However, like most modes, it had its drawbacks. Starting with the most basic chart, the white balance, we observed a pronounced dominance of red in SDR and HDR modes. Although green also appeared in HDR mode, it did not significantly affect the overall perception. This resulted in an image with a noticeable yellow tint, particularly evident on the whites and the faces of the actors.

Another important chart, arguably more significant, is gamma, which controls contrast in materials with a standard colour palette. In factory mode it performed reasonably well, but with one notable issue regarding the darkest scenes. Here, it was significantly lowered, resulting in excessive brightening, which robbed the film of its contrast and suspense.

As for HDR content, the white balance remained similar. The main change occurred in the EOTF curve chart. Initially, we saw a bulge that, like the gamma curve, brightened the darkest scenes considerably. However, the curve then drastically changed, and the measured result dropped below the reference line, diminishing the dynamism of the film even further.

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.

Samsung even with its entry-level televisions, provides advanced tools for calibration, and we put these to work. The results of our efforts were more than satisfying. The white balance, which previously had a strong yellowish tint in both scenarios, now looks much improved, although slight deviations from the ideal are still noticeable. Nevertheless, the image is significantly cleaner than before the calibration process. We were able to model the gamma well for SDR materials, achieving as much contrast as the television can provide. The EOTF curve has also been adjusted, preventing the image from becoming excessively lightened or darkened. However, it is worth noting that for HDR materials, the deltaE errors remain quite high, with the primary issue being the unit's insufficient brightness.

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.

Let’s revisit the smoothing of tonal transitions function. It can be set to either "off" or "auto." As expected, setting it to "off" results in significant gradation issues. On the other hand, when set to "auto," both movies and TV shows offer smoother colour transitions. However, this function has notable drawbacks: it interferes with the director’s intent by softening the effect of film grain and, more concerning, it often blurs small details, misinterpreting them in the process. For this reason, we consider this feature ineffective and do not recommend using it, as the tests for tonal transition smoothness were conducted with this function turned off.

Next, we assessed the image scaling, which is crucial for watching lower-resolution materials. Unfortunately, as this is one of the manufacturer’s lower-end models, the scaling function does not perform well. The result is heavily blurred details, and a noticeable white halo forms around characters, detracting from the viewing experience.

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.

Although the Samsung DU7192 is the entry-level model in the manufacturer’s range, it does come equipped with motion smoothing technology. While this feature is somewhat limited in comparison to higher-end models, its inclusion is a notable advantage in its price category. The maximum refresh rate available on the TV is 60 Hz, which is adequate for movies and TV shows but falls short for fast-moving content like sports.

Within the motion smoothing settings, there are two features aimed at improving fluidity: "Motion Blur Reduction" and "Clear Motion (LED)." We’ll discuss the latter later, but first, let’s focus on the former. Unfortunately, despite being present, we found no noticeable difference when adjusting this setting. Regardless of the chosen option, the picture maintained the same stuttering effect typically associated with 24 fps content.

The Samsung DU7192 uses a panel with an average response time. However, it is worth noting that this type of panel outperforms VA panels in a similar price range, making it a more suitable option for watching sports compared to other budget models.

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.

The Samsung DU7192 is equipped only with HDMI 2.0 ports, which is to be expected given the device's price point and its target consumer market. As a result, it does not support the highest resolutions or frame rates available on the latest generation consoles. It does, however, feature the basic gaming functionality of ALLM (Auto Low Latency Mode). Unfortunately, it is disappointing that the manufacturer did not include GameBar, a feature that has become a standard even in lower-end TVs. GameBar would have provided significant convenience by allowing gamers to easily adjust settings quickly during 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.
