XIAOMI S Mini 2026 (85"-98") 144Hz vs Samsung M80H

The larger versions of the Xiaomi S Mini 2026 offer very similar HDR capabilities. Peak brightness reaches around 1000 nits, which for a TV in this price bracket is a very solid result. This is most apparent in bright scenes, where large, strongly lit parts of the picture can look truly impressive. The TV has enough brightness headroom that HDR does not amount to merely a slightly brighter image. Very small points of light appearing on an almost completely black background fare worse. In such cases the local dimming system significantly limits their brightness so as not to illuminate neighbouring parts of the picture and to preserve deep blacks. As a result, small highlights or single lamps do not have the same intensity as in much more expensive models. This, however, is typical behaviour for Mini LED TVs and hard to treat as something unique to Xiaomi.

HDR colours

The issue of colours is similarly close. Although the manufacturer uses the term QLED, the expansion of the colour gamut here is achieved by a PFS phosphor. In our measurements the TV covered around 94% of the DCI-P3 colour space and about 74% of the much more demanding BT.2020. In practice this delivers well-saturated colours in most HDR material and it is hard to point to any obvious shortcomings. Limitations appear mainly with the most saturated shades of green, which the TV is no longer able to reproduce in full.

The M80H is not among the brightest TVs. Its peak brightness is around 350 nits and we saw similar results in most of our test scenes. That is not enough to achieve truly striking HDR; bright highlights lack the necessary punch and the overall image is a bit too dark. In practice HDR on the M80H resembles a well-presented SDR image more than noticeably more dynamic material with a wide brightness range. The image can still look acceptable, but it is hard to speak of strong specular highlights, clearly glowing light sources or an effect that immediately distinguishes HDR from ordinary content.

Colours

One of the M80H's stronger points is its colours. The TV uses a filter based on PFS backlighting, which allows it to display a much wider colour gamut than a standard LCD screen without filters. Our measurements confirm this – the M80H covers around 96% of the DCI-P3 gamut and 72% of BT.2020. Those are really good figures, which allow colours to be deeply saturated. Samsung's approach here is interesting. The M80H is not part of the QLED family, even though in terms of colour it is practically indistinguishable from models carrying that badge. From an image-quality point of view it doesn't really matter though — the colours are simply good.

In the larger versions of the Xiaomi S Mini 2026 Film mode performs best, although the factory settings here are not without faults. In SDR the white balance was noticeably warm due to an excess of red. In HDR it was the opposite: there was too much blue and not enough red, which made the image cooler. Moreover, both the gamma response in SDR and the EOTF curve in HDR were slightly above the reference values. In practice this produced a slightly brighter image, particularly in the mid-tones. It was not a major fault, but with more demanding material you could notice that the image was not reproduced entirely as the creators intended.

Filmmaker Mode is set fairly well out of the box, although it falls short of perfection. In SDR material the most noticeable issue is an excess of red in the white balance, which makes the image appear a little warmer than it should. HDR content has a similar character. As for the brightness response, in SDR the gamma stays close to the target value for most of the range. Small deviations are mainly visible in darker areas, which in places are a bit too crushed. In HDR the darkest details are slightly lifted, while from around 65% brightness the image begins to be slightly darkened. This is largely due to the way the TV controls its brightness. Overall, Filmmaker Mode looks pretty good straight out of the box, but the picture can still be improved.

After calibration we mainly managed to even out the white balance, so colours look much more natural in both SDR and HDR. We also improved the gamma response, so the SDR picture is no longer unnecessarily brightened and holds closer to the reference values. The only major issue remaining is in HDR. Xiaomi still manages brightness a little too aggressively and renders some scenes brighter than it should. It looks better on larger sizes than on the 55–75 inch models, but the EOTF curve still runs slightly above the reference. In practice HDR is therefore slightly brightened, even though colour reproduction after calibration is already very good.

After calibration, the M80H fares very well, especially with the most ordinary SDR content. Regular broadcast TV, YouTube and films watched without HDR can look very good on it. After correcting the white balance the errors are small, although sometimes we can still see that the TV tends to overdo the most saturated reds. In HDR it is also possible to improve the picture and correct its main faults, but it is not at the level of pricier models. Samsung quite heavily restricts colour adjustment in HDR, so in many areas we have to accept what the TV offers out of the box. Calibration lets us improve some parameters, but we are no longer able to change the overall character of the M80H's image.

The larger Xiaomi S Mini 2026 variants also use the MT5896 processor and perform similarly in terms of digital image processing. Upscaling is not one of this model's strengths. Low-resolution content is upscaled to 4K in a fairly basic way, and there is not as effective retrieval of fine detail as in more refined televisions. The 85 and 98 inch versions do include a feature intended to reduce posterisation, but its effectiveness is very limited. After switching it on it is hard to notice any real improvement, so the TV still does little to address visible banding between colours.

Although the M80H is positioned fairly low in Samsung's range, the manufacturer equipped it with one of its stronger processors, the NQ4 AI Gen2. The same chip can be found, for example, in Neo QLED TVs and the lower-tier S85H OLED. That is good news, because when it comes to improving weaker sources the processor performs really well. Upscaling is the strongest point. Low-resolution content is displayed correctly and edges do not look overly jagged. Of course the TV will not create details that are not present in the source, but regular broadcast TV and older recordings look decent on it. One drawback is the overscan effect, that is edge cropping, which cannot be completely turned off. The tonal transition smoothing function, the so-called noise reduction, also works well. The processor can effectively reduce visible traces of heavy compression, but it does not do this without side effects. At higher settings it may over-smooth the image, remove some fine detail and even eliminate film grain. For that reason we recommend using this function mainly for content that really suffers from strong compression and posterisation.

The biggest difference between the various sizes of the Xiaomi S Mini 2026 concerns the panel's refresh rate. The 55 to 75-inch variants use a 60 Hz panel, which in practice results in noticeably less smooth motion than the larger versions. This is most apparent when watching sport, fast-paced scenes or gaming, where the picture is not as smooth and sharp in motion.

The M80H performs very well for watching sport and for gaming. The TV is fitted with a panel offering a refresh rate of up to 144 Hz at 4K, and when the resolution is lowered to Full HD it can even support 240 Hz. PC gamers will benefit most from the latter.

The panel also handles content displayed at 120 Hz well, which is particularly important for console gaming. The high refresh rate is also useful when watching sport, and motion blur is relatively limited. That matters because VA panels are not known for top results in this area. With the M80H, fast-moving objects do not show pronounced smearing.

Unfortunately, the smaller versions of the Xiaomi S Mini 2026 have a significant limitation for gamers: a 60 Hz panel. In 4K we are therefore limited to 60 fps and cannot fully take advantage of the PS5 or Xbox Series X. It is possible to run 120 Hz, but only after dropping the resolution to 1080p or 1440p. Apart from that, it’s all fairly sensible. The TV supports ALLM and automatically switches to game mode when it detects a console. There is also a Game Bar that lets you quickly check the most important gaming settings. Our biggest reservation concerns HGiG. The HDR calibration screens on the PS5 and Xbox do not match the TV’s actual capabilities. If you set HDR exactly according to them, some of the brightest elements may simply be blown out.

The M80H could be a very good choice for gamers on a slightly smaller budget. In terms of features it offers essentially the same as far more expensive Samsung TVs. All three HDMI ports support the 2.1 standard, so even if one is taken by a soundbar connected via eARC there is still room for a PC and consoles. There is also VRR that runs up to 144 Hz at 4K and up to 240 Hz at Full HD. Samsung has also correctly implemented HGiG, so after performing HDR calibration on a console games are properly matched to the screen’s capabilities. This won't make the M80H any brighter, but at least it won't unnecessarily crush the brightest parts of the image. There's also a Game Bar for quick access to key settings and a Gaming Hub that lets you play in the cloud without a console. The M80H also offers Game Motion Plus, which creates additional frames and improves the smoothness of games running at 30 or 60 fps. Input lag then rises to around 59 ms, but is still roughly three times lower than with ordinary motion smoothing on TVs from other manufacturers. We wouldn't really recommend it for online gaming, but in more relaxed titles it can perform very well.
