Compare: Xiaomi S Mini 2025 vs TCL A300W NXTVision

Xiaomi, well known as a giant in the smartphone market, has decided to fight for the attention of high-end technology enthusiasts by presenting a television with MiniLED backlighting. The S MiniLED 2025 model looks truly impressive on paper. The vast number of dimming zones provides excellent contrast, and the brightness, reaching impressive levels, can impress both in high-quality HDR materials and in older SDR. The television performs excellently where smooth motion is key. The high refresh rate panel and low input lag make it a good choice not only for sports fans but also for gamers. Support for features such as ALLM and GameBar further enhances the gaming experience. Google TV on this television works as it should – quickly, smoothly, without unnecessary stutters, which we could not say about the model A Pro 2025. Additionally, with such an extensive application library, it will satisfy even the most demanding user. However, not everything looks so good in practice. Despite solid hardware specifications, the television has its drawbacks. The biggest problem is the algorithms managing the dimming zones, which can be quite irritating when watching films in the evening. The operation of individual zones is overly noticeable in dynamic scenes, which can effectively distract our attention from the image. Issues also arise in more demanding HDR scenes despite the truly impressive brightness. Small, bright elements often lose brightness, ruining the effect that a top-quality image should provide. The system is also not free from shortcomings – image enhancement features for lower-quality materials work unevenly, and some options in Google TV are poorly translated or even untranslated. The Xiaomi S MiniLED 2025 has huge potential, but in its current form, it seems underutilised. It is clear that Xiaomi wanted to create something truly good, but several significant shortcomings result in a mixed final effect. A device with high aspirations that needs better software to truly shine. It is an ideal television for brighter rooms, where high screen brightness plays a key role, and local dimming issues become less noticeable. It will also perform excellently as a screen for gamers and for those who value the versatility and functionality of the Google TV system.

At first glance, it is clear that the TCL A300 NXTVision aims to be more than just an ordinary television. It offers an image display mode that – unlike its competitors from Korea, Samsung The Frame – is completely free. Additionally, just like its rivals, it comes with freebies. In the packaging, besides the television, we find extra frames mimicking light wood and a flat wall mount, allowing the television to actually resemble a gallery piece. In terms of everyday use, the standout feature is the Google TV system – extensive, quick, and offering access to a vast number of applications. And if we feel like stepping out of the digital museum and jumping straight into the world of gaming, the A300 can surprise us. Two HDMI 2.1 ports, 144 Hz, VRR, ALLM, and very low input lag ensure that even demanding gamers can feel at home here. Well... perhaps except for those who are sensitive to motion blur – as this remains one of the major issues with this model. There are also downsides. Although the image mode is free – and that is worth appreciating – the quality of the available graphics is clearly lacking compared to what Samsung offers in its paid ART Store. The displayed images resemble photos rather than realistic reproductions of artworks. Unfortunately, the A300 – like the rival Hisense S7NQ – performs poorly here and additionally has certain software issues. The brightness of the television itself also leaves much to be desired – it is the darkest television of the entire "frame trio," which translates to average experiences during the day and limited HDR effect. Nevertheless, the TCL A300 NXTVision is quite a reasonable alternative to Samsung The Frame or S7NQ – especially if we are looking for a cheaper solution without additional fees for access to the "gallery" mode and with an operating system that does not limit us in terms of the number of applications. However, it is essential to remember that this is a proposition with a significant amount of compromises. If we want to save a bit and do not expect top-notch picture quality, then the A300 could be a hit in the picture stakes. Otherwise, it is worth taking a look at its competition.

Xiaomi S MiniLED is one of the most affordable MiniLED technology televisions available on the market. The model we tested, with a size of 55 inches, features as many as 308 local dimming zones, which is impressive for this price. Additionally, it uses a VA panel, which naturally offers significantly better contrast than IPS panels. On static test images, the television performed excellently, achieving an impressive contrast ratio of 182,000:1 in the film Oblivion. The blacks were deep, and the details in the light and dark areas of the image were clearly separated. However, in more demanding scenes where the image is dynamic, the situation becomes complicated.

Where lies the problem? The main cause is the local dimming algorithms. Although their work shows promising results on static images, during film playback – that is, in the natural working conditions of the television – they operate too aggressively. In dynamic scenes, such as those from the tested film, you can see how the individual dimming zones "work and flicker," which detracts from the viewer's sense of image coherence. This effect is particularly noticeable in motion, when bright objects move against a dark screen. As a result, although Xiaomi S MiniLED offers excellent contrast on paper, in practice the effect is less satisfying. The aggressive operation of the algorithms spoils the perception of dynamic scenes, making the television average in this category. It's a good example of how MiniLED technology requires not only good specifications but also proper optimisation.

The TCL A300, also known as NXTVision, uses a VA panel, so right from the start, one could expect decent contrast. On our test charts, the television indeed showed typical results for this type of panel – in the best case, the contrast reached around 5000:1, which is not a bad result for this segment.

However, it should be noted that the model is not equipped with any local dimming technology, which unfortunately is noticeable in practice. The black levels, though quite deep at times, often lean towards navy blue or grey – especially in darker scenes. In short: for a television without local dimming, it's not bad, but it cannot be compared to models that already have this feature on board.

Since the Xiaomi S MiniLED boasts an impressive number of 308 dimming zones, it is time to test 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. Do these figures, however, translate to real experiences in film scenes? In the case of less demanding shots, such as 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 power of HDR effects.

Unfortunately, much like with contrast, it wasn't without issues. When smaller, brighter elements appear on the screen – as in the challenging scenes from Sicario 2 – the aggressive operation of the dimming zones spoils the entire effect. Brightness in 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 receives a muted, almost flat impression, which takes away all the enjoyment from the viewing experience.

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

When it comes to brightness, the TCL A300W is definitely the darkest television among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, this is immediately noticeable. In our measurements, the peak luminance reached a mere 400 nits, and on test film patterns, this value dropped to 350 nits. This is definitely too little to experience the true “magic” of bright HDR effects. As a consolation – the television is equipped with a PFS LED coating (which is something like QLED), providing very good coverage of a wide colour gamut, both DCI-P3 and BT.2020. In addition, it has full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the lack of brightness and helps improve the overall perception of content in this quality.

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 reflect a reference image, but the reality turned out to be somewhat different.

Let's start with the test of SDR content. Here, the television had quite a few issues, especially with white balance. The clearly visible dominance of red made the image look too warm, with all colours taking on a reddish hue. This was particularly noticeable in a comparative scene from the film Star Wars. 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 content, the situation improved significantly. The white balance, although still not perfect, was much more balanced, with a slight dominance of red and blue, but without 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, for example, in the test scene from the film Pan that we described earlier. These brightening effects may disturb the precision of the image, but in 4K, the overall effect was much more acceptable than in SDR.

Although Xiaomi S MiniLED can pleasantly surprise with 4K content, its factory settings in SDR require solid adjustments, especially regarding white balance and brightness. This is definitely a television that would benefit from calibration.

TCL A300 offers several picture modes, but without a doubt, the best is the movie mode. Unfortunately, although it is the best option available, it is not free from errors. In both HD and HDR content, the image has a noticeably too warm hue - it leans slightly towards pink, which is particularly noticeable in scenes with snow. Instead of pure white, we get a pinkish tint that spoils the natural perception of colours.

The management of brightness is also not very good. In the case of older HD material, the image often seems too dark - which is confirmed by the inflated gamma value. Conversely, with HDR content, the effect is the opposite - the image is overly bright, which we observed in scenes from the film Pan. Such a lack of consistency also affects the accuracy of colour reproduction - a test with the ColorChecker showed that many samples clearly deviate from the reference values.

Fortunately, TCL allows for manual adjustment of settings, so we decided to check how the television would perform after our professional calibration. The effects of this adjustment are described below.

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

In SDR mode, the white balance is nearly perfectly aligned. The errors are so minimal that in many cases they can be considered negligible. This is confirmed by the results of the Colour Checker palette, where the errors did not exceed a value of 2 ΔE – this is really a rare result. Gamma also performs very well, 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 perception of the image.

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

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

After our professional calibration, the TCL A300 has literally received a new lease of life. The image has stopped being too warm, and the colours finally look as they should – which was confirmed by the ColorChecker test, where the colour samples finally started to hit their marks, at least to some reasonable extent. It was also possible to partially correct the brightness management – the image is now more balanced and less "wobbly" between different types of content. Of course, certain limitations cannot be overcome – a slightly noticeable blooming effect is still present, but that is a characteristic of the technology and not something that can be eliminated even after professional settings.

Generally speaking: after calibration, the A300 performs significantly better and gains a completely new quality.

The fluidity of tonal transitions in Xiaomi S MiniLED 2025 is impressive. Even in the theoretically most difficult scene with red water, the television performs excellently – we did not notice any major issues. Minor imperfections occur in scenes like The Kingsman or The Martian, where subtle colour blending can be observed. Nevertheless, Xiaomi stands out in this category, offering one of the best qualities of tonal transitions in its price range. This is definitely a strong point of this television.

TCL A300 NXTVision is another frame-style television that handles transitions of tones really well. It's hard to find distinct bands or sharp transitions between shades of the same colour – the overall appearance is natural and smooth.

However, it must be admitted that among the three tested models (The Frame and S7NQ), TCL performs the worst in this category. In darker and lighter scenes, slight imperfections can be noticed. Nonetheless, looking at it as a whole, for a television in this price range – it presents itself really solidly. It may not be the best of the bunch, but it maintains a very good level.

When it comes to tonal transitions in lower quality materials, such as YouTube or television, the Xiaomi S MiniLED is equipped with a feature called "Colour Contour Removal." At the "low" setting, it performs quite well, although its effectiveness can be inconsistent. Sometimes it seems as though the television is struggling to smoothen, which creates a certain dissonance. On the positive side, we did not notice any visible side effects, although due to the instability of this feature, one could suspect that unexpected issues may arise in certain situations.

Image scaling also performs moderately. There is some slight jaggedness, particularly on thin elements like branches, and subtitles can appear slightly jagged. While this may not be very bothersome, a more discerning eye will certainly pick up on these shortcomings. Overall, most users should be satisfied with the quality of scaling and smoothing, but the television will not satisfy those who expect perfection in every frame of the image.

TCL A300 handles tonal transitions in high-quality films very well, but the question arises – how does it perform with weaker material? The television is equipped with a tonal transition smoothing function, but its effectiveness can be described in one word: "random." In one scene it could work and improve the gradation, but when turned off… the effect remains the same. There is a lack of consistency and predictability.

Image scaling is also not one of A300's strong points. On the test chart, the main character actually looked better than on the raw signal, but with thin lines – such as fonts or background details – there was noticeable jaggedness and aliasing. On the positive side, the television does not crop the image and has no problems with overscan, but the overall quality of scaling is rather average.

Xiaomi S MiniLED 2025 is equipped with a panel featuring a refresh rate of 4K@120Hz (1080p@240Hz), which provides sufficient smoothness for both watching dynamic sports broadcasts and playing the latest games. This level of refresh rate makes the image appear fluid, even in the most intense scenes. Additionally, the television offers a “Motion Smoothing” feature that allows you to adjust the way the image is displayed in films. You can choose a more frame-like effect, typical of the cinematic experience, 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 favourite content.

The TCL A300 is equipped with a 144 Hz panel, which should immediately satisfy practically everyone – both gamers and sports fans. The motion is smooth and the image is clear even during fast-paced scenes. Additionally, the television offers motion enhancement functionality called "Motion," where we find two sliders on a 10-point scale. These allow you to adjust the effect to your own preferences – from a classic, cinematic look with visible frames to a very smooth (though somewhat unnatural) image reminiscent of soap opera effects. This way, everyone can find a setting that suits them.

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 will appreciate during dynamic games without annoying lags. Regardless of what we connect, it functions smoothly, and the television handles various resolutions exceptionally well. There is also the GameBar, which may not look as impressive as the "bars" from the competition, but makes up for it with practicality. It is 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 must admit that operating the television itself – or rather finding the gaming features within it – posed a significant challenge for us. We approached the testing of the Xiaomi S MiniLED 2025 several times to locate 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, and allows for enabling picture 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 an exceptional gaming experience. Unfortunately, the intuitiveness of the menu itself leaves much to be desired and may pose a challenge for the average user.

TCL A300 is a television designed not only to transport us to a digital art museum but also to a full-fledged gaming world. Here, we find practically everything one could expect from gaming equipment: two full-bandwidth HDMI 2.1 ports, 144 Hz refresh rate, VRR support, and ALLM.

The proper implementation of the HGIG mode also deserves praise – something that competitor Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which older console or PC owners will appreciate.

In addition, there is an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is really well-prepared for top-level gaming – it's just a shame that issues with smearing slightly tarnish its overall image as a gaming device.

The input lag of the Xiaomi S MiniLED 2025 is one of its biggest advantages. 8 ms for 120 Hz content and 17 ms for 60 Hz is an absolutely remarkable performance that will satisfy even the most demanding gamers. Furthermore, the Dolby Vision mode in games deserves praise. Unlike many competing models, Xiaomi maintains a low input lag even in this mode, making it an excellent choice for fans of high-quality HDR gaming experiences.

In terms of input lag, the TCL A300 performs really well. Values below 10 ms at a refresh rate of 120 Hz are something many gamers dream of – such low lag is practically unnoticeable, both during everyday gaming and in more demanding e-sports titles. One might criticise the result of 23 ms in Dolby Vision mode at 60 frames, but it is still a sufficiently low value that it's hard to have serious objections. In this category, the A300 really excels.

Xiaomi S MiniLED 2025 is a good choice if we need a television for working with a computer. The fonts are very clear thanks to the support for chroma 4:4:4, making it perfect for office work or browsing documents. It also performs excellently in gaming – high refresh rates, G-SYNC, and low input lag ensure smooth gameplay, which will satisfy most gamers.

If we plan to use the TCL A300 as a monitor for a computer, we may be pleasantly surprised. The television performs really well in this role. It is equipped with a 144 Hz panel, supports G-Sync, and, as we have already mentioned, offers very low input lag, so gaming on it with a connected PC is a pure pleasure.

Working with text is also possible, though with some limitations. The TCL A300 has slight issues displaying dark fonts and thin lines – this stems from the subpixel structure, which in everyday use can be somewhat bothersome, although it looks better in photos than in reality.

The television supports chroma 4:4:4, but only up to 120 Hz. Therefore, we have indicated that this feature is available, but with a limitation – if we care about perfectly readable fonts, it is advisable to stick to a refresh rate of 120 Hz. At 144 Hz, the sharpness of the text may suffer slightly.

In terms of viewing angles, Xiaomi S MiniLED 2025 does not impress. This is a typical problem with VA panels, which do not perform well without additional coatings that widen viewing angles. The image begins to lose quality when watching the television from the side – colours fade and contrast significantly drops. However, the advantage of VA panels is their considerably better contrast compared to IPS panels, which in turn win in terms of wider viewing angles. This is a classic compromise where one has to choose between better blacks and a more universal image seen from various places in the room.

The viewing angles on the TCL A300 NXTVision are – let's be honest – mediocre. The television is equipped with a VA panel, which inherently has rather limited angles and unfortunately this is evident here. The video below speaks for itself – even a slight deviation from the axis results in a noticeable drop in contrast and colour saturation. It's a shame that this is yet another frame-style television that has done absolutely nothing about it. After all, we don't always have the opportunity to sit perfectly straight on – especially if the device is also intended to serve a decorative function in the living room.

Xiaomi S MiniLED 2025 is equipped with a satin finish on the panel, which performs fairly well in reducing reflections. On the screen surface, one can notice light reflections, which can be somewhat distracting in bright rooms. However, the key feature that saves this television in daytime use is its brightness. With a value of 841 cd/m², the screen performs effortlessly even in very sunny interiors. This is more than enough to comfortably watch television, films, or sporting events. Importantly, the television also handles more demanding content, such as winter sports, where the dominant white can pose a significant challenge for other televisions. Here, Xiaomi definitely delivers.

The TCL A300 NXTVision is equipped with a matte panel very similar to the one found in one of its Chinese competitors – the Hisense S7NQ model. Such a surface handles reflections fairly well, although it must be said that it performs worse than Samsung's The Frame, which offers a significantly higher level in this regard. As is often the case with matte displays, blacks lose their depth during the day and appear more gray than black – and this is no different here. Unfortunately, the fact that the A300 is the darkest television of the three tested does not help either. As a result, it has a real problem standing out in brightly lit rooms.

Xiaomi S MiniLED 2025 is a television that stands out thanks to the Google TV system. It offers access to the most popular streaming services, music apps, and various useful features that significantly enhance the everyday experience of using the television. For those who enjoy personalisation, the system also provides plenty of configuration options.

The built-in voice assistant operates smoothly – we can not only control the television but also ask about the weather forecast or set a reminder for the next day. Unfortunately, we noticed during testing that some features have difficulty translating into Polish, which can be frustrating, especially for those less adept at navigating the settings. Despite this, the overall impression is very good, and minor shortcomings can be corrected in future updates.

The device manages connectivity well. Wireless connections to Windows computers or Apple devices proceed smoothly, and thanks to Bluetooth, we can easily connect headphones, keyboards, or other accessories. The remote control is simple and convenient – it works from any position, so aiming at the screen is not necessary. However, there are some shortcomings. If someone frequently uses traditional television, they may feel the lack of recording features from tuners or the PiP (picture in picture) option. This somewhat limits capabilities, but for those focusing on streaming and modern functionalities, it shouldn't be a significant issue.

Xiaomi makes up for these shortcomings with an excellent operating system. Google TV is one of the most advanced and user-friendly systems available on the market, which makes the television perform really well in everyday use.

The TCL A300 is a television styled to resemble a painting, which can successfully masquerade as a work of art during everyday use, hanging on the wall. It is equipped with a special image display mode, additional frames in a light wood tone, and a flat wall mount that allows the television to be hung like a true picture – flush against the wall.

A significant advantage of the image mode is that it is completely free. We have access to dozens of works from which we can choose the one to be displayed in standby mode – instead of a black screen, the picture we selected remains on the wall. The quality of the graphic reproductions is decent, but it must be admitted that it clearly falls short of that from the Samsung ART Store. Although access to images there is paid, the quality of the scans is significantly better – you can see the texture of the paint, the canvas, and the details. In the TCL A300, it resembles high-quality photographs more than realistic reproductions of artworks. Additionally, the implementation of the image mode in the system leaves much to be desired. For example – if we set the brightness in image mode to 10%, that same value automatically transfers to the normal viewing mode, where we could comfortably set the brightness to 50% or even 100%. This works in the opposite direction too – when we set the brightness to 100% in normal mode, switching to gallery mode displays the images with that same maximum brightness, shining too intensely and losing the entire effect of a “picture on the wall.” These are minor but annoying errors that can ruin the experience of what was intended to be visually subtle and elegant.

Moving on to more classic features – the A300 runs on the Google TV system, which currently offers by far the largest selection of applications (the full list available below). The well-functioning voice assistant with support for the Polish language is also a major plus. As standard – as in most TCL televisions – the USB recording function or picture-in-picture (PiP) mode is missing.

The basic file player in Xiaomi S MiniLED 2025 does its job for simple video materials. However, a noticeable drawback is the lack of support for Polish characters, which can be problematic for those using subtitles.

Fortunately, the presence of the Google TV system allows for an easy workaround of this limitation. Thanks to it, alternative file playback applications can be installed, which handle Polish characters and offer much more extensive options. As a result, the limitations of the built-in player are not as burdensome as one might think.

The built-in player in the TCL A300 works as it should – most popular video and photo files play without any issues. There is a lack of support for the HEIC format from Apple (which is quite common in many televisions), but most users still use AirPlay, so this shouldn't be a major problem. If someone is not satisfied with the default player, the Google TV system offers considerable options – it's easy to install an alternative app that better suits our tastes. Nevertheless, it must be acknowledged that the factory solution is entirely sufficient for everyday use.

Xiaomi S MiniLED 2025 plays really nicely and even offers a light bass, reminiscent of the sound known from the lower model, namely A Pro 2025. The sound is well balanced, making watching films or listening to music comfortable, even without additional audio equipment. Interestingly, the television effortlessly supports audio formats such as Dolby Atmos and the less common DTS:X. This means you can connect a home cinema system or soundbar and enjoy spatial sound without any difficulties. A nice addition is also the presence of a standard speaker jack.

When it comes to sound, the TCL A300W – like its competitors – plays quite... flat, after all, we are talking about a super flat television. For everyday watching of news or series, this level is entirely sufficient, but during film screenings, we may clearly miss depth and space. On the plus side, it is worth noting that the television supports both Dolby Atmos and the increasingly rare DTS:X – which offers more options when connecting an external audio system. It is also worth mentioning that the A300 PRO model has been equipped with a dedicated, flat soundbar. And not just any soundbar – it performs better than most of the televisions we have tested.
