Xiaomi S Mini 2025 vs Samsung QN80H

Since the Xiaomi S MiniLED boasts an impressive number of 308 dimming zones, it is time to test 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. Do these figures, however, translate to real experiences in film scenes? In the case of less demanding shots, such as 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 power of HDR effects.

Unfortunately, much like with contrast, it wasn't without issues. When smaller, brighter elements appear on the screen – as in the challenging scenes from Sicario 2 – the aggressive operation of the dimming zones spoils the entire effect. Brightness in 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 receives a muted, almost flat impression, which takes away all the enjoyment from the viewing experience.

In summary, if we are looking for a television with high brightness for watching films during the day, the Xiaomi S MiniLED will easily fulfill that task. However, its inability to precisely manage the dimming zones means that watching films in the evening, especially in demanding HDR scenes, can be more frustrating than satisfying.

The Samsung QN80H is undoubtedly a bright TV. In synthetic tests it exceeds the 1000-nit mark, which on paper promises a solid HDR effect. In practice the screen really shows its teeth, although it can't fully spread its wings (or its backlight, if you will 🤔) in every condition. Bright, wide scenes make the best impression. Well-lit outdoor shots and brightly lit scenes look really good on it. Brightness then stays around 700 nits, which provides a noticeable step up in quality compared with standard SDR. Problems start in dark scenes with small, pinpoint highlights. The QN80H tends to dim these strongly, in order to protect black depth at all costs. On the one hand this gives better contrast, on the other... you lose dynamics and the brilliance of fine HDR detail. So the TV has considerable potential, but the dimming algorithm can be too restrictive.

Colour gamut coverage

When it comes to colours it's good as well. The QN80H uses quantum dot technology, and in our measurements it covered 93% of the DCI-P3 colour space and about 70% of BT.2020. Today those results aren't exactly jaw-dropping, but in real-world use they're more than sufficient to deliver a vivid, natural image for most films and TV series. Colours are suitably saturated, and after proper calibration they don't look artificial or overly aggressive.

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 reflect a reference image, but the reality turned out to be somewhat different.

Let's start with the test of SDR content. Here, the television had quite a few issues, especially with white balance. The clearly visible dominance of red made the image look too warm, with all colours taking on a reddish hue. This was particularly noticeable in a comparative scene from the film Star Wars. 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 content, the situation improved significantly. The white balance, although still not perfect, was much more balanced, with a slight dominance of red and blue, but without 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, for example, in the test scene from the film Pan that we described earlier. These brightening effects may disturb the precision of the image, but in 4K, the overall effect was much more acceptable than in SDR.

Although Xiaomi S MiniLED can pleasantly surprise with 4K content, its factory settings in SDR require solid adjustments, especially regarding white balance and brightness. This is definitely a television that would benefit from calibration.

The factory settings of the QN80H performed really well, especially compared with the majority of TVs we receive for testing. Of course, our measurements were taken in Filmmaker Mode, and that's the mode we recommend turning on immediately after the initial setup. For SDR material, our sample was set up surprisingly well. The white balance was very even, colours looked natural, and errors were so small they were hard to notice without measurement equipment. The only weaker point was the gamma. In the brighter parts of the image the TV brightened them a little too much, which at times made the picture lose some depth. Still, we'd like most TVs to look this good straight out of the box.

It fared a little worse in HDR. The white balance was still set correctly, so the problem was not with the colours but with the way the QN80H managed image brightness. This was immediately visible on the EOTF chart. The TV brightened large parts of scenes too much, causing the brightest elements to clip. Interestingly, very small points were often dimmed too much at the same time. As a result, some fine details simply disappeared. So the factory Filmmaker mode in HDR is not bad, but it is definitely not as well calibrated as in SDR.

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

In SDR mode, the white balance is nearly perfectly aligned. The errors are so minimal that in many cases they can be considered negligible. This is confirmed by the results of the Colour Checker palette, where the errors did not exceed a value of 2 ΔE – this is really a rare result. Gamma also performs very well, 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 perception of the image.

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

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

We saw the biggest difference after calibration in HDR Filmmaker mode. SDR was already very good out of the box, so we didn't have much work to do there. In HDR, however, we managed to get to grips with the way the QN80H handled brightness, as it had been over-brightening most scenes. After calibration the picture is calmer, more natural and much closer to how a faithful image should look.

When it comes to tonal transitions in lower quality materials, such as YouTube or television, the Xiaomi S MiniLED is equipped with a feature called "Colour Contour Removal." At the "low" setting, it performs quite well, although its effectiveness can be inconsistent. Sometimes it seems as though the television is struggling to smoothen, which creates a certain dissonance. On the positive side, we did not notice any visible side effects, although due to the instability of this feature, one could suspect that unexpected issues may arise in certain situations.

Image scaling also performs moderately. There is some slight jaggedness, particularly on thin elements like branches, and subtitles can appear slightly jagged. While this may not be very bothersome, a more discerning eye will certainly pick up on these shortcomings. Overall, most users should be satisfied with the quality of scaling and smoothing, but the television will not satisfy those who expect perfection in every frame of the image.

Digital image processing in the Samsung QN80H is handled by the second-generation NQ4 AI processor. It's a chip we already know from the manufacturer's earlier models, and it still performs very well, especially with lower-resolution content. The image is effectively upscaled to 4K, but without excessive sharpening and without giving the impression the TV is aggressively trying to improve the source material.

The "Noise Reduction" function also proves useful. It can noticeably reduce posterisation and visible banding in lower-quality material, particularly in low-bitrate streaming. However, it's important to remember that it does not work without side effects. It can remove some film grain and slightly smooth the image. So with a high-quality source we'd leave this function switched off. If, however, someone is more bothered by banding and uneven tonal transitions than by the loss of some grain, "Noise Reduction" can be a really useful addition.

Xiaomi S MiniLED 2025 is equipped with a panel featuring a refresh rate of 4K@120Hz (1080p@240Hz), which provides sufficient smoothness for both watching dynamic sports broadcasts and playing the latest games. This level of refresh rate makes the image appear fluid, even in the most intense scenes. Additionally, the television offers a “Motion Smoothing” feature that allows you to adjust the way the image is displayed in films. You can choose a more frame-like effect, typical of the cinematic experience, 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 favourite content.

Motion handling and motion clarity on the QN80H are really good, mainly thanks to the fast panel. In 4K the screen refreshes at up to 144 Hz, and when switched to Full HD and connected to a PC it can reach as much as 240 Hz. That's new for Samsung TVs and a useful addition for people who want to use the TV for PC gaming as well. We were more interested, however, in how the QN80H performs at 120 Hz, because consoles use that refresh rate. Here it performs very well. The panel does not suffer greatly from the smearing typical of VA panels, and light trails behind moving objects are mainly visible on dark backgrounds. That said, it's nothing that would interfere with normal watching of sport or gaming. The TV also has a motion smoothing system that Samsung calls "Wyrazistością obrazu". You can adjust judder reduction and blur reduction separately, so it's easy to tailor its behaviour to films, sport or your own preferences.

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 will appreciate during dynamic games without annoying lags. Regardless of what we connect, it functions smoothly, and the television handles various resolutions exceptionally well. There is also the GameBar, which may not look as impressive as the "bars" from the competition, but makes up for it with practicality. It is 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 must admit that operating the television itself – or rather finding the gaming features within it – posed a significant challenge for us. We approached the testing of the Xiaomi S MiniLED 2025 several times to locate 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, and allows for enabling picture 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 an exceptional gaming experience. Unfortunately, the intuitiveness of the menu itself leaves much to be desired and may pose a challenge for the average user.

The Samsung QN80H is a TV that stands out when it comes to gaming features. The biggest new addition for 2026 is DLG mode, which allows refresh rates of up to 240 Hz when the image is switched to Full HD. It's an option aimed mainly at PC users, but it also shows that Samsung is still heavily developing the gaming side of its TVs. However, the list of advantages doesn't end there. The QN80H has four full-fledged HDMI 2.1 ports, which is still not standard at this price point. So you can connect several consoles, a PC or a soundbar at the same time without having to wonder which port supports the full video capabilities. The TV also supports VRR, ALLM and HGiG, so it's hard to fault its basic feature set.

A downside is the lack of Dolby Vision, which may matter primarily to Xbox Series X owners. However, this is not a flaw that disqualifies the QN80H as a gaming TV. Samsung has a feature most manufacturers still lack: its proprietary motion smoothing, Game Motion Plus. It's a motion smoothing system that works in game mode too, allowing you to improve the smoothness of titles running at 30 or 60 frames per second without a drastic increase in input lag. In practice, Game Motion Plus can make a much bigger difference than the Dolby codec, especially in more demanding games that don't offer a 60 FPS mode. The image becomes noticeably smoother, while controls remain sufficiently responsive. So despite the lack of Dolby Vision, the QN80H remains one of the best-equipped gaming TVs in its class.
