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 1,000 nits, which is a very solid result for a TV at this price point. This is most apparent in bright scenes, where large, heavily lit areas of the image can look really striking. The TV has enough brightness headroom that HDR isn't reduced to just a slightly brighter image. However, very small pinpoint highlights on an almost completely black background perform worse. In those situations the local dimming system significantly reduces their brightness to avoid illuminating adjacent image areas and to preserve deep blacks. As a result, small specular highlights or single lamps don't have the same intensity as in much more expensive designs. This is, however, typical behavior for Mini LED TVs and is hard to treat as something unique to Xiaomi.

HDR colors

Color performance is similarly comparable. Although the manufacturer uses the term QLED, the expanded color gamut here is achieved by a PFS phosphor. In our measurements the TV covered about 94% of the DCI-P3 color space and about 74% of the much more demanding BT.2020. In practice this yields well-saturated colors in most HDR material and it's hard to point to obvious shortcomings. Limitations appear mainly with the most saturated shades of green, which the TV can no longer reproduce in full.

The M80H is not one of the brightest TVs. Its peak brightness is around 350 nits and we saw similar results in most of our test scenes. That's not enough to produce genuinely impressive HDR — bright highlights lack punch and the overall image is a bit too dark. In practice, HDR on the M80H resembles a well-presented SDR image more than clearly more dynamic wide-range content. The picture can still look fine, but it's hard to point to strong specular highlights, clearly bright light sources, or an effect that immediately separates HDR from ordinary content.

Colors

One of the M80H's strengths is its color. The TV uses a PFS-based backlight filter, which allows it to display a significantly wider color gamut than a standard LCD screen without filters. Our measurements confirm this — the M80H covers about 96% of the DCI-P3 gamut and 72% of BT.2020. Those are very good results, which let the colors appear strongly saturated. Samsung's policy here is interesting. The M80H is not part of the QLED family, even though in terms of color it is practically on par with models carrying that label. From an image-quality standpoint, that doesn't matter much; the colors 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 flaws. In SDR the white balance was noticeably warm due to an excess of red. In HDR the situation was the opposite: there was too much blue and too little red, which made the image cooler. Additionally, both the gamma curve in SDR and the EOTF curve in HDR were slightly above the reference values. In practice this resulted in a slightly brighter image, especially in the midtones. It wasn't a major fault, but with more demanding content you could tell the image wasn't reproduced exactly as the creators intended.

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

After calibration, we were mainly able to even out the white balance, so colors in both SDR and HDR look much more natural. We also improved the gamma curve, so SDR content is no longer unnecessarily bright and stays closer to reference values. The only significant remaining issue is in HDR. Xiaomi still controls brightness a bit too aggressively and renders some scenes brighter than it should. That is less noticeable on larger screen 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 color reproduction after calibration already looks very good.

After calibration, the M80H performs really well, especially with basic SDR content. Regular broadcast TV, YouTube, or movies viewed without HDR can look very accurate on it. After correcting the white balance, errors are minor, though you can still sometimes see that the TV tends to oversaturate the most saturated reds. In HDR you can also improve the picture and correct its main faults, but it doesn't reach the level of pricier models. Samsung quite heavily restricts color adjustment options 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 image character of the M80H.

Larger variants of the Xiaomi S Mini 2026 also use the MT5896 processor and perform similarly in terms of digital image processing. Upscaling is not a strong suit of this model. Low-resolution content is upscaled to 4K in a fairly basic way and it does not recover fine detail as well as more refined TVs. The 85- and 98-inch versions do include a feature intended to reduce posterization, but its effectiveness is very limited. With it turned on it's hard to notice any real improvement, so in scenes with visible color banding the TV still does little to address it.

Although the M80H is positioned fairly low in Samsung's lineup, the manufacturer equipped it with one of its stronger processors, NQ4 AI Gen2. The same chip can be found in Neo QLED TVs and the lower-tier OLED S85H. That's good news, because the processor does a very good job improving weaker source material. Upscaling performs best. Low-resolution content is displayed properly, and edges don't look overly jagged. Of course the TV won't create details that aren't in the source, but regular broadcast TV and older recordings look decent on it. One drawback is overscan, that is, edge cropping, which cannot be fully disabled. The tonal transition smoothing feature, the so-called noise reduction, also works well. The processor can effectively reduce visible signs of heavy compression, but it does so not without side effects. At higher settings it can overly smooth the image, remove some fine detail, and even eliminate film grain. Therefore we recommend using this feature primarily for content that actually has problems with heavy compression and posterization.

The biggest difference between the various sizes of the Xiaomi S Mini 2026 is the panel's refresh rate. The 55–75-inch models use a 60 Hz panel, which in practice means noticeably less motion smoothness than the larger versions. It's easiest to notice this when watching sports, fast-moving scenes, or playing games, where the picture isn't as smooth or clear in motion.

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

The panel also handles 120 Hz content well, which matters especially for console gaming. The high refresh rate is useful for watching sports too, and motion blur is relatively low. That’s important because VA panels are not known for the best results in this respect. With the M80H, fast-moving objects do not produce a very noticeable trail.

Unfortunately, the smaller versions of the Xiaomi S Mini 2026 have a significant limitation for gamers: a 60 Hz panel. In 4K we're therefore limited to 60 fps and can't fully take advantage of the PS5 or Xbox Series X. You can run 120 Hz, but only after dropping the resolution to 1080p or 1440p. Otherwise it's fairly reasonable. The TV supports ALLM and automatically switches to Game Mode when it detects a console. There's also a Game Bar that lets you quickly view the most important gaming settings. Our biggest issue is with HGiG. The HDR calibration screens on the PS5 and Xbox don't match the TV's actual capabilities. If you set HDR exactly according to them, some of the brightest highlights may simply be clipped.

The M80H can be a very good choice for gamers on a slightly smaller budget. Feature-wise it offers essentially the same as Samsung's much more expensive TVs. All three HDMI inputs support HDMI 2.1, so even if one is taken by a soundbar connected via eARC there’s still room for a PC and consoles. There’s also VRR up to 144 Hz at 4K and up to 240 Hz in Full HD. Samsung has properly implemented HGiG as well, so after performing HDR calibration on the console, games are appropriately matched to the screen’s capabilities. That won’t make the M80H any brighter, but at least it won’t unnecessarily wash out the brightest parts of the image. There’s also a Game Bar for quick access to the most important settings and a Gaming Hub that lets you play in the cloud without a console. The M80H also includes Game Motion Plus, which creates extra frames and improves the smoothness of games running at 30 or 60 fps. Input lag then rises to about 59 ms, but it’s still roughly three times lower than with the typical motion smoothing on other manufacturers’ TVs. We don’t really recommend it for online multiplayer, but in more relaxed titles it can work very well.
