XIAOMI S Mini 2026 (85"-98") 144Hz vs SONY BRAVIA 3 II (XR35M2)

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.

Bravia 3 II is certainly not a TV that tries to impress with brightness. In our measurements it reached about 450 nits, so it falls well short of the brightest models on the market. That does not mean HDR is just a paper feature. Compared with ordinary SDR material, the brightest elements of the image can already come through noticeably, and reflections, highlights and stronger exposures have a bit more energy and stand out better from the rest of the scene. This is most obvious in simpler shots where the screen displays many bright elements. Then the Bravia 3 II can give a hint of a higher dynamic-range picture. The problem only begins with more demanding content, where much greater brightness headroom is required. There the TV quickly shows its limitations and instead of powerful, striking HDR we get only a competently rendered picture.

Colours

Bravia 3 II uses a QLED-type panel, although technically it does not use a classic quantum dot layer. Instead Sony has used a solution based on PFS phosphor, which performs a very similar role: it allows more saturated reds and greens and thus enables a much wider colour gamut. In measurements DCI-P3 coverage was around 94%, and the very wide BT.2020 around 74.4%. These are good results for this class of hardware, which mean the Bravia 3 II has no problem reproducing sufficiently saturated colours in HDR content. Colours do not look washed out, and more intense hues can look genuinely attractive.

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.

In Professional mode the Bravia 3 II already delivers a fairly good level of colour reproduction straight out of the box. In SDR the most noticeable issue is a slightly low gamma, which makes the midtones a little brighter. White balance isn't perfect either; as brightness increases the blue and red components become slightly lacking, so whites can at times take on a marginally warmer, faintly greenish tint. These are not faults that immediately catch the eye when watching a film. Average error values hover around 3, so the factory setting can be regarded as quite good. The situation is similar in HDR. Here too there is a slight lack of the blue component, so the image is marginally warmer than the reference, but the difference is not large enough to significantly interfere with normal viewing.

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, there is particularly a lot to be gained from SDR content. The white balance was set almost perfectly, the gamma practically matches the reference value, and the average colour errors fell from around 3 to about 1. That is already a level at which differences from the reference image are, in practice, very difficult to detect. The Bravia 3 II therefore shows that, despite its position in Sony’s lineup, it has quite a lot of potential for precise picture calibration. Improvements are also visible in HDR, although here it is no longer possible to avoid all the limitations of the TV itself. After evening out the colours, it is easier to notice that the EOTF curve in film content runs slightly below the reference value in places, so the Bravia 3 II gently darkens part of the image. This is not an ideal solution from a reference point of view, but in this particular TV it also has its benefits. With no local dimming and average black levels, this behaviour slightly reduces the visibility of the backlight in darker scenes and helps maintain a stronger impression of contrast. So you could say Sony partly masks the limitations of the panel this way, instead of trying at all costs to stick to the reference luminance.

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.

The Bravia 3 II is Sony's first TV to use the new MediaTek Pentonic 800 chipset, and there are a few changes in image processing. Starting with the basics. The upscaling itself is adequate. The TV can sensibly pull up lower-resolution material and does not have a strong tendency to over-emphasise jagged edges or other source imperfections. With regular broadcast TV or weaker streaming material the picture therefore remains quite pleasing. We have more reservations about the digital image processing. In this model Sony has replaced the well-known "Smooth Gradation" function with a new setting called "Digital Noise Reduction". Its role is essentially very similar: it is supposed to smooth unpleasant tonal transitions and artefacts resulting from heavy signal compression. Unfortunately, this function performs noticeably worse than before. At the "High" setting (the only one that had any visible effect) the TV can smooth away too many elements of the image at once, causing film grain to disappear and the texture of objects or even skin to start looking unnatural. Worse still, the effect is not particularly stable. When a scene contains more motion, the function's effect clearly weakens and at times it looks as if the TV stops intervening in the picture altogether. For everyday viewing we therefore would not recommend using it at a high level. It can help on a static shot, but the price is often an excessive loss of detail.

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.

Motion handling is definitely one of the Bravia 3 II's strongest points. The TV uses a 120Hz VA panel, a solution that, by nature, despite the high refresh rate, does not always cope well with motion blur. Here, however, Sony has managed to keep that problem very well under control. Fast-moving objects remain crisp, and the characteristic trails and blurring are reduced to a very low level, if not to zero. It is one of the least motion-blur-prone LCD TVs we have tested. Interestingly, in this respect the Bravia 3 II can even outperform the much more expensive True RGB flagship series, the Bravia 9 II.

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.

Sony Bravia 3 II is a very good TV for gamers, although not everything has been implemented exactly as we would like. The biggest change concerns the connectors. For the first time in a Sony TV we get as many as four full HDMI 2.1 ports with 48 Gb/s bandwidth, thanks to the new MediaTek Pentonic 800 chipset. That removes one of the issues that has plagued this manufacturer’s TVs for years. We can connect several devices at once and on each input use the device’s full capabilities, for example VRR or ALLM. There is also a simple Game Bar that lets you view key signal parameters and change a few useful settings, such as black level, when you want to improve visibility in darker parts of a game. However, there are two limitations worth knowing. The first is the lack of support for 1440p at 120 Hz. That will not be a problem for everyone, but people using that resolution on a console or PC, for example to get higher frame rates in certain games, will have to choose 1080p. We have more reservations about HGiG support. Sony does not allow you to disable the TV’s tone mapping on the Bravia 3 II, so the screen is always processing HDR content even when you would prefer to leave that task to the console. This is most obvious during HDR setup — the checkerboard pattern does not disappear at the point that corresponds to the TV’s actual capabilities. That does not mean HDR in games will look bad. You just need to approach the setup a little differently and, instead of relying on the pattern, manually set the peak brightness to around 450 nits. The issue can be worked around, but you should know about it before you start setting up the console.
