Panasonic W70A vs Xiaomi S Mini 2025

HDR on the Panasonic W70A unfortunately does not impress. A brightness level of 250–300 nits is simply too low to feel the true magic of cinematic effects in dynamic, bright scenes. Images that should “explode” with light appear rather flat, and fine details in bright areas often get lost in the average luminance of the panel. On the plus side, the HDR effect is at least stable. The TV does not suffer from excessive brightening nor lose details with sudden scene changes. Everything is predictable and calm, though unfortunately lacking in impact. Another issue is the colour gamut coverage. The W70A is not equipped with an additional layer of quantum dots (often known as QLED), which is why the colours appear rather average. There is a lack of depth in reds, saturation in greens, and precision in reproducing subtle shades.

Since Xiaomi S MiniLED boasts an impressive 308 zones of dimming, it's 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. But do these numbers translate to real-life experiences in film scenes? In the case of less demanding shots, such as those from the film The Meg, the television indeed delivered excellent results, reaching up to 900 nits. Such values are impressive and can truly convey the strength of HDR effects.

Unfortunately, just like with contrast, there were some issues. When smaller, brighter elements appear on the screen – as in challenging scenes from Sicario 2 – the aggressive action of the dimming zones ruins the entire effect. Brightness in these moments drops to just 100 nits. That is definitely too little to convey the full magic of HDR. Instead of a dynamic and detailed image, the viewer gets a muted, almost flat impression, which takes away all the enjoyment of the viewing experience.

In summary, if we're 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 the dimming zones makes watching movies in the evening, especially during demanding HDR scenes, potentially more frustrating than satisfying.

The Panasonic W70A was tested in movie mode, which theoretically should guarantee the most natural image reproduction. Unfortunately, as is often the case with budget televisions, reality turned out to be far from ideal.

In HD (SDR) content, the white balance was significantly disrupted by an excess of red and a noticeable drop in blue tones. The result? The image had a distinctly warm, almost yellowish glow, which is clearly visible in the comparison photo. In the case of 4K HDR materials, the situation reversed. Here, the image became excessively cold and bluish, causing scenes to lose their naturalness and depth. The differences are visible even to the naked eye, especially in the bright areas of the image. The Colour Checker palette test confirmed our observations. Most colour samples did not hit their intended points, 'drifting' towards warmer shades in SDR and cooler ones in HDR. In terms of brightness characteristics, both gamma and the EOTF curve showed significant issues. The image tended to excessively brighten certain areas, disrupting the balance and leading to a loss of detail in both darker and brighter regions.

In summary – the factory colour reproduction settings in the Panasonic W70A leave much to be desired. The image is far from neutral, and errors in white balance and gamma mean that solid calibration is needed to extract the full potential from this television.

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

Let’s start with the SDR material tests. Here the TV had quite a few problems, especially with white balance. The noticeable dominance of red made the image appear too warm, and all colours gained a reddish hue. This was particularly evident in the comparative scene from the film Star Wars. The brightness characteristic (gamma) also left much to be desired – instead of a smooth transition, we had a real "rollercoaster," with visible excessive brightening of the screen.

In 4K materials, the situation looked considerably better. The white balance, though still not perfect, was much more balanced, with a slight dominance of red and blue, but no excessive impact 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 in the test scene from the film Pan that we described above. These brightening effects may disturb the precision of the image, but in 4K, the overall effect was far more acceptable than in SDR.

Although Xiaomi S MiniLED can pleasantly surprise in 4K materials, its factory settings in SDR require significant corrections, especially regarding white balance and brightness. It's definitely a TV that would benefit from calibration.

Panasonic W70A, despite its limitations, gave us plenty of room to manoeuvre during calibration. Thanks to well-developed tools, we were able to achieve a much better white balance in both HD (SDR) and 4K HDR content. The issues with excessive red in SDR and overly cool images in HDR have disappeared. The gamma brightness characteristics have also been improved, now maintaining stability and not leading to excessive brightening or loss of detail in darker areas.

So where is the problem? Unfortunately, there are barriers that even professional calibration cannot overcome. Poor coverage of a wide colour gamut means the television cannot fully convey colours in HDR materials. There is a lack of saturation, and subtle colour transitions still appear somewhat “flattened.” Another limitation is the brightness management due to the IPS panel used. In a comparison photograph with an actress's face in colourful clothing, it is clearly visible how some shades are distinctly muted, and colours lose their depth and vibrancy.

Calibration has extracted from the W70A as much as it could. The image is now much more natural, and the factory setting errors have been effectively corrected. Unfortunately, the hardware limitations in the form of poor colour gamut coverage and an average panel mean that even after calibration, we are unable to achieve spectacular effects, especially in HDR content.

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

In SDR mode, the white balance is almost perfectly aligned. The errors are so minimal that in many cases they can be considered negligible. This is confirmed by the Colour Checker palette results, where errors did not exceed 2 ΔE – a truly rare outcome. Gamma also performs very well, although there are slight brightening effects in the darkest elements at the beginning of the graph. However, this is a minor exception that does not significantly affect the viewing experience.

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

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

We checked how the Panasonic W70A handles upscaling content that is lower quality than 4K, and I must admit that the TV performs quite decently in this regard. The feature responsible for smoothing tonal transitions is called "Zeroing Counter." The optimal setting turned out to be the Average option, which effectively smooths out colour gradation issues while not ruining the film grain. This is the setting we recommend for most users, as it provides a balance between enhancing the smoothness of transitions and maintaining the naturalness of the image.

When it comes to image scaling, the Panasonic W70A performed really well. The test chart with the model looked positive – details in her clothing were well reproduced, and the contours of her face maintained sharpness. In the background, we noticed a slight "jagginess" on thin branches, but these are details that only a very attentive eye will catch. However, it's worth noting a certain quirk of this model – the TV has a tendency to overscan, meaning it slightly crops the edges of the image. It’s not a very intense phenomenon, and for most users, it will be practically unnoticeable, but if we care about perfectly framing the shot, it's worth keeping this in mind.

When it comes to tonal transitions in lower-quality materials, such as YouTube or television, the Xiaomi S MiniLED comes with a feature called “Colour Contour Removal.” In the "low" setting, it works quite well, but its effectiveness can be uneven. Sometimes it appears as if the TV struggles to smooth things out, which creates a bit of dissonance. On the plus side, we didn’t notice any visible side effects, although given the instability of this feature, one might suspect that unexpected issues could arise in certain situations.

Image scaling also comes across as average. There’s slight jaggedness, especially on thin elements like branches, and text can be a bit ragged. It may not be overly bothersome, but a more discerning eye will certainly catch these imperfections. 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.

The Panasonic W70A is equipped with a 60 Hz panel, which immediately suggests that the TV is best suited for watching movies, series, or everyday television content. In more dynamic scenes, such as sports broadcasts or games, the limitations of the panel become more noticeable. However, it is worth noting the presence of a motion smoother called “Effect”, which offers three levels of adjustment – low, medium, and high.

Each setting allows you to adjust the smoothness of motion to your own preferences, minimizing the motion blur effect and improving the clarity of dynamic shots. In practice, the Medium setting seems to be the most universal – it offers better smoothness without the excessive “soap opera effect” that can look artificial in feature films. The High setting may work well for sports broadcasts, but in movies, it can disrupt the natural character of motion.

Xiaomi S MiniLED 2025 is equipped with a 4K@120Hz (1080p@240Hz) refresh rate panel, providing sufficient smoothness for both watching dynamic sports broadcasts and playing the latest games. This level of refresh rate makes the image look fluid, even in the most intense scenes. Additionally, the television offers a "Motion Smoothing" feature that allows users to adjust the way the image is displayed in films. We can choose a more choppy effect, typical for cinematic experiences, or a smoother one, resembling the so-called "theatrical effect". As a result, every user can tailor the settings to their preferences and enjoy smooth images in their favourite content.

The Panasonic W70A is a TV that is likely to suit casual gamers more than hardcore players. The 60 Hz refresh rate doesn't fully utilise the potential of next-gen consoles, especially in dynamic titles. The lack of HDMI 2.1 slightly limits its capabilities, but fortunately, it includes features like ALLM, which automatically switches to game mode, and VRR, which helps minimise screen tearing. It's also worth noting the support for Dolby Vision in games and HGiG, making HDR more predictable and looking solid. It's a pity, though, that it lacks Game Bar. This feature is now standard in many TVs and provides quick access to the most important settings for gamers. The W70A performs well for gaming, but it does have its limitations. It will do fine with more laid-back titles, but more demanding gamers may feel unsatisfied.

Xiaomi S MiniLED 2025 is a television that has a lot to offer gamers. With two HDMI ports boasting 48 Gbps bandwidth, we can easily connect modern consoles or PCs, utilising their full potential. Additionally, the ALLM feature automatically switches the TV to low latency mode – something we appreciate during fast-paced gaming without annoying lags. No matter what we connect, it runs smoothly, and the TV handles various resolutions exceptionally well. There’s also the GameBar, which may not look as flashy as the "bars" on competing models, but makes up for it in practicality. It’s a straightforward settings panel that allows us to quickly change the most important options or check stats – a perfect solution when time is of the essence.

However, we must admit that navigating the TV itself – or rather, finding gaming features – was quite a challenge for us. We approached the Xiaomi S MiniLED 2025 test several times to locate all the necessary options. The hidden menu allowed us to discover the "GameBoost" feature, which enables switching the TV to 240 Hz mode, activating VRR, and allows for enabling the image in HGIG mode.

In summary, the Xiaomi S MiniLED 2025 is a TV that definitely deserves praise in the gaming equipment category. Its rich set of features – 240 Hz mode, VRR, HGIG, and "GameBoost" – provides an exceptional gaming experience. Unfortunately, the intuitiveness of the menu itself leaves much to be desired and can pose some challenges for the average user.
