Samsung Q6F (IPS) vs XIAOMI S Mini 2026 (55"-75") 60Hz

Unfortunately, the Samsung Q6F is a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is definitely too low to even talk about any "high dynamic range" or HDR effect. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another issue is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire screen to artificially improve the black levels. This results in the image becoming even darker, with brightness sometimes dropping below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not of the highest quality, as the coverage of the DCI-P3 colour gamut does not exceed 90%. Because of this, colours in HDR content may simply appear unsaturated.

When it comes to HDR, the Xiaomi S Mini 2026 performs really well, especially given the segment this model sits in. The TV can reach around 1000 nits of brightness without much difficulty, so in bright scenes it can deliver a very pronounced HDR effect. The sun, highlights or very brightly lit parts of the picture can be intensely bright and at times really hit you with their intensity. It’s a bit different in dark scenes, though. Very small light sources surrounded by black are rendered at much lower brightness, so they lack the pinpoint intensity seen on the best TVs. That’s not unusual for a Mini LED. The local dimming algorithm reduces the backlight in those cases to preserve as deep a black as possible, which in such scenes matters more than a few extra nits.

HDR colours

Colour reproduction also fares well. Xiaomi markets the S Mini 2026 as a QLED TV, although the solution used here is in practice based on a PFS phosphor. What matters is the result, and that is pretty good. Measured DCI-P3 gamut coverage was around 94%, while in the much wider BT.2020 colour space it was about 74%. That means the TV can show most of the colours used in HDR movies with suitably high saturation. Its limitations are most noticeable with very intense shades of green, where the colour range begins to run out.

We tested the television in Filmmaker mode, which showed us two completely different sides of this model. Looking at SDR content, we were honestly shocked at how good this television looks straight out of the box. It was really hard to pick on anything here. Despite a slight 'messiness' in white balance and some slightly brightened details in the blacks (which directly stems from the IPS panel construction), colour errors hovered around the '2' level. This is not only a surprisingly good result but rather phenomenal, considering the price of the device.

On the other hand, what the Q6F showed in terms of colours when switched to HDR mode was a very unpleasant surprise. The errors in colour reproduction and palette were so massive that our charts literally ran out of scale. Of course, since Samsung even in such a budget model offers very extensive calibration options, we decided to approach the issue professionally and see what could be done during calibration.

We tested the Xiaomi S Mini 2026 (55–75 inch models) in Film mode, which compared with the other presets offered the most accurate colours. That did not mean the image was correctly set up straight away. In our unit the white balance was noticeably shifted toward warmer tones. There was too little blue and too much red, giving whites and greys a slightly warm cast. The TV also tended to brighten darker parts of the image too much. This was due to the gamma, which instead of staying around 2.4 fell in places to about 2.0. That made shadow detail more visible, but the image lost some depth. So the factory settings weren't bad, but they still needed some adjustment to reproduce the picture accurately.

After our calibration, the colours in SDR mode looked even better – the result is truly surprising, as colour errors at a level of "1" are something typically seen in devices costing several thousand dollars. In this respect, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our intervention in HDR mode did not yield a noticeable improvement. The television, due to its weak blacks and low coverage of a wide colour gamut, still has significant issues with proper colour saturation, especially reds. This is an example of a device where HDR primarily exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

Surprisingly, the Xiaomi S Mini 2026 responds quite well to calibration. After our adjustments we were able to noticeably improve the white balance and the picture stopped leaning toward overly warm tones. In SDR material the result is really good, with the TV able to reproduce such content very accurately and hard to fault for colour reproduction. We made similar adjustments in HDR, although not everything could be corrected there. Colours look better than on the factory settings, but the TV still tends to display the picture a little brighter than it should. You can see this from the EOTF curve, which sits above the reference. In practice this means some HDR scenes are brighter than the creators intended. It's a quirk of this TV and we can't do anything about it.

Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good, even for such an inexpensive QLED model. The only downside is when watching very low-resolution materials like 576p (typical for old DVD players) – the image may appear slightly cropped. This is because the TV does not allow the option to turn off the Overscan feature, which is a common issue with Samsung devices.

The situation is completely different when it comes to digital processing, or the attempt to smooth the image of unwanted artifacts. Here, the TV completely fails. Although in the menu we find a feature called "Noise Reduction," it does not produce any noticeable results regardless of the slider setting. The only thing it seems to do is introduce undesirable errors into the image. Despite its presence in the system, we definitely do not recommend using it.

The MT5896 processor handles digital image processing in the Xiaomi S Mini 2026. Unfortunately, in this respect the TV is fairly average. Low-resolution content isn't upscaled very well, and its limitations become obvious on a large screen. The picture looks quite digital, and the TV can't pull out many extra details. You also can't turn off overscan for low-resolution content. The handling of posterisation smoothing is even worse. On the smaller models there's not even a separate setting to reduce the visible banding between similar shades. So if those imperfections are already present in the source material, Xiaomi effectively doesn't mask them.

The 60 Hz panel in the Samsung Q6F is standard in this price range, making it a rather average model for dynamic sports or gaming. However, when it comes to movies, the TV performs quite well thanks to its smoothing feature. The "Motion Vibration Reduction" option allows you to adjust the motion smoothness to your own preferences – from preserving a cinematic feel to full smoothness.

The smaller variants of the Xiaomi S Mini 2026 use a 60 Hz panel, and that's their biggest limitation when it comes to motion. For films and TV series this isn't yet a major problem, because the TV has a classic motion interpolator for 24/30 fps material. So you can reduce the characteristic judder and adjust motion to your own preferences. Sports and other 50/60 Hz material fare worse, because there’s no additional feature to improve smoothness. In such content we’re therefore limited by the panel itself.

In terms of motion blur the TV performs fairly typically for a VA panel. The most trailing is visible behind objects moving against a dark background, while in brighter scenes the effect is noticeably smaller. It’s not at a level that completely ruins the perception of motion, but in dynamic scenes you can see that the panel isn’t one of the fastest.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does include features like ALLM (Auto Low Latency Mode) and VRR frame syncing for consoles, that's pretty much where the list of advantages ends. Beyond these basics, the television offers nothing more that could satisfy those who spend a lot of time in front of a console. It's a real shame that a useful tool like Game Bar, which allows for quick control of game parameters in higher-end Samsung models, is missing here. In terms of gaming, this is an absolutely basic model and it will only suit 'casual' gamers.

In the larger sizes the Xiaomi S Mini 2026 becomes a far more interesting option for gamers. The panel runs natively at up to 144 Hz, so when you connect a PC you can use the high refresh rate even at 4K. At lower resolutions the TV can go even further, reaching up to 288 Hz. It also offers ALLM, automatic switching to Game Mode, and a Game Bar that keeps the most important settings within easy reach. Of course, the TV has two full-bandwidth HDMI 2.1 ports. So in terms of smoothness the difference compared with the 55–75 inch versions is substantial and particularly easy to notice when using a PC or console. However, not everything works perfectly. As with the smaller variants, we have reservations about the HGiG implementation. The HDR setup screens on the PS5 and Xbox don't precisely reflect the TV's actual capabilities, so if you set the console according to those prompts the brightest parts of the image can be blown out and lose some detail.
