Xiaomi S Mini 2025 vs Samsung Neo QLED QN70F / QN74F / QN77F

Since the Xiaomi S MiniLED boasts an impressive number of 308 dimming zones, it was time to see 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. However, do these numbers translate into real experiences in movie scenes? In the case of less demanding shots, like 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 strength of HDR effects.

Unfortunately, similar to the contrast situation, there were issues. When smaller, brighter elements appear on the screen – as in challenging scenes from Sicario 2 – the aggressive operation of the dimming zones spoils the whole effect. Brightness during 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 gets a muted, almost flat impression, which diminishes the enjoyment of the viewing experience.

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

QN70F is a TV that can positively surprise when it comes to brightness. In ideal test conditions, it reaches even 800 nits, which – for this price range – is really solid. Of course, that's a result from measurement test patterns, so we decided to check how it performs in practice, with real movies. Here, the TV somewhat tones down its capabilities. In most of the tested scenes – for example, in "The Meg" – the actual HDR brightness was around 500 nits. That's still a good result that allows you to enjoy HDR effects, although it is far from perfect. On the other hand, we have a QLED screen with a quantum dot layer, which means very good color reproduction capabilities. The colors are vivid and saturated. QN70F covers about 94% of the DCI-P3 color space, and in the wider BT.2020 gamut, it exceeds 75%, so in this regard, there's nothing to be ashamed of.

Xiaomi, like many manufacturers, offers a wide range of picture modes. On the S MiniLED, we can find both IMAX Enhanced and Filmmaker. We conducted our tests in Filmmaker mode, which theoretically is supposed to reference the original image, but the reality turned out to be somewhat different.

Let's start with the test of SDR materials. Here, the television had quite a few problems, especially with white balance. The clearly visible dominance of red made the image appear too warm, and all colors gained a reddish tint. This was particularly noticeable in a comparative scene from the Star Wars movie. 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 materials, the situation looked much better. The white balance, while still not perfect, was much more balanced, with a slight dominance of red and blue, but without excessive influence 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 Pan movie that we described above. These brightening effects can disrupt image precision, but in 4K, the overall effect was much more acceptable than in SDR.

Although the Xiaomi S MiniLED can positively surprise in 4K materials, its factory settings in SDR require significant adjustments, especially in terms of white balance and brightness. It is definitely a television that would benefit from calibration.

We tested the QN70F in the best default picture mode, which is Filmmaker Mode. It must be said that in this particular test unit, the factory settings performed quite well. The picture was calm, natural, and despite minor deviations, pleasant to perceive. The biggest flaw was a slight dominance of red in the white balance, which caused a slight pinkish tint to the entire scene. However, this was not a glaring flaw – rather subtle and only noticeable when directly compared to a properly calibrated screen. A somewhat larger issue appeared in the brightness characteristic. The television tends to understate the brightness of parts of the image that should be displayed more brightly. As a result, some details can appear slightly dimmed – not so much lost entirely, but not as clearly pronounced as they should be. Nevertheless, as far as a television in this category and in these settings goes, we consider the result to be a good starting point for further calibration.

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

In SDR mode, the white balance is nearly perfectly aligned. The errors are minimal enough that in many cases they can be considered negligible. This is confirmed by the Colour Checker palette results, where the errors did not exceed 2 ΔE – a result that is indeed quite rare. Gamma also looks very good, 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 image perception.

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

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

After calibration, the QN70F shows that it can offer a really high level of color reproduction. It nearly perfectly balanced the white point, and the values in the Color Checker test dropped below 3 – that is, below the threshold at which the average eye can perceive differences. The image looks natural, and the colors are accurately represented, without excessive saturation or the coolness known from factory settings. It must be said that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after proper adjustment, can come close to much more expensive models in terms of color accuracy. The only thing one could still criticize is the brightness characteristics. There is still a tendency to brighten the smallest parts of the image – particularly those that should remain darker. However, this is a design feature of this model, not a calibration error. Despite this, the final effect definitely deserves recognition.

When it comes to color transitions in lower quality materials like YouTube or television, the Xiaomi S MiniLED is equipped with the "Color Contour Removal" feature. In the "low" setting, it works quite well, but its effectiveness can be uneven. Sometimes it seems like the TV struggles with smoothing, which creates a certain dissonance. On the plus side, we did not notice any visible side effects, although given the instability of this feature, one might suspect that unexpected issues could arise in some situations.

Image scaling also performs average. There is slight aliasing, especially on thin elements like branches, and subtitles can appear a bit jagged. While it may not be very bothersome, a more discerning eye will certainly catch these shortcomings. Overall, most users should be satisfied with the scaling and smoothing quality, but the TV may not satisfy those who expect perfection in every frame.

Samsung QN70F offers a distortion reduction feature that improves the smoothness of tonal transitions. In "Standard" mode, it works quite well - smoothing problematic transitions without significantly interfering with the image structure. Film grain is partially removed, but details such as texture or skin structure still remain visible. The "High" mode operates much more aggressively. The smoothing is stronger, but it comes at the cost of a noticeable loss of detail. Therefore, in practice, we recommend sticking with the "Standard" setting or completely turning off this feature. The improvement in gradation may be less spectacular, but the image retains more naturalness.

When it comes to scaling low-quality content, the QN70F performs very well. Tests with lower resolution images were really impressive. Despite slight aliasing of contours, everything looks clean and clear, even if the original content was very poor. It's just a shame that the TV has an overscan issue that cannot be completely turned off. As a result, the image from very low resolution may be slightly cropped, which is mainly visible on subtitles or the interface.

Xiaomi S MiniLED 2025 is equipped with a display that refreshes at 4K@120Hz (1080p@240Hz), providing sufficient smoothness for both watching dynamic sports broadcasts and playing the latest games. This level of refresh rate makes the image look smooth, even in the most intense scenes. Additionally, the TV offers a "Motion Smoothing" feature that allows users to adjust the way images are displayed in movies. We can choose a more frame-like effect, typical of cinematic experiences, 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 favorite content.

The QN70F is a television with a refresh rate of 144 Hz, which puts it at the forefront in terms of image smoothness. Whether we are watching dynamic sports broadcasts or playing on a console, the picture looks very good. There is no feeling of stuttering, chopping, or the typical "tearing" in fast motion that is common in lower-end models. Samsung also allows you to adjust the smoothness to your own preferences. In the picture clarity settings, we find options such as blur reduction and motion smoothing – each of which can be adjusted independently. This is especially useful when watching content with a lower frame rate and we want to give it a smoother, more cinematic character – or on the contrary, maintain the natural film "feeling" of 24 frames.

Xiaomi S MiniLED 2025 is a television that has a lot to offer gamers. With two HDMI ports with 48 Gbps bandwidth, we can easily connect modern consoles or PCs, utilizing their full potential. Additionally, the ALLM feature automatically switches the television to low latency mode – something we will appreciate during dynamic games without annoying lags. No matter what we connect, it works smoothly, and the television handles various resolutions well. There is also GameBar, which may not look as impressive as the "bars" from the competition, but makes up for it with practicality. It's 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 have to admit that operating the television itself – or rather finding the gaming features – was quite a challenge for us. We approached the Xiaomi S MiniLED 2025 test several times to find 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 at 120Hz, and turning on the image 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 exceptional gaming experiences. Unfortunately, the intuitiveness of the menu itself leaves much to be desired and may pose a certain challenge for the average user.

Samsung QN70F is truly a solid choice for gamers. Here we have as many as four HDMI 2.1 ports with full bandwidth of 48 Gbps, which means full support for gaming in 4K at 144 Hz refresh rate. In addition, we have all the basic features we expect today: auto low latency mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar with information about the mode, resolution, and frame count.

It's also worth highlighting the Game Motion Plus feature, which allows you to add artificial frames to games running at 60 fps or less. It works surprisingly well and in many titles – especially those where consoles struggle to maintain a stable framerate – it improves gameplay smoothness without significant lag.

Unfortunately, there are also some drawbacks. The lack of support for Dolby Vision mode is not surprising – it's a standard for Samsung. But the much bigger disappointment is the absence of the HGiG feature. What's worse, it was removed in a software update, leaving users who previously used it quite shocked. Without HGiG, you can't manually set the maximum HDR brightness from the console, which results in some games looking slightly washed out – especially if the TV misinterprets the tonal range. Why did Samsung, a brand that has set standards in gaming features for years, decide to take such a step? It's hard to say. At the time of writing this review, the tested TV was running on software version 1110 – and frankly, if you care about full support for gamers, it's better to temporarily hold off on updates.
