Compare: Samsung QLED Q70D / Q74D / Q77D vs Xiaomi S Mini 2025

Samsung Q70D performed in the test exactly as it should for its price range – very competently. The strongest aspects of the television are certainly its performance when using a console and colour reproduction after the calibration process. The former will undoubtedly catch the attention of gamers with a range of conveniences that Samsung Q70D can offer, and there are quite a few, including that which is almost exclusive to the manufacturer's units – the ability to smooth out gameplay while still maintaining reasonable input lag, allowing titles running at 30 fps to perform like those at native 60 frames per second. In the context of gaming, one cannot forget the well-implemented HGIG mode, which, when set correctly, is on par with games using Dolby Vision. We must also acknowledge the easy pairing of the television with the Canal+ decoder, which is not such an obvious advantage, but we know that many people experience issues with this. Staying on the topic of television, it must be noted that the Samsung Q70D offers very good brightness in SDR content for its price range, making daytime viewing more than comfortable. A downside for the tested television is the lack of Dolby Vision, which would have significantly enhanced performance at the maximum brightness of the Samsung Q70D. The device's construction flaws should not be overlooked, as they may (though not necessarily) lead to light bleed that can be noticed in dark situations during dimly lit scenes. What cannot be taken away from the Samsung Q70D is the fact that it features one of the better motion smoothers in its price bracket, which works excellently for sports events or fast-paced action scenes. The system responsible for the television's operation runs very smoothly, and the only thing we can criticise it for is the absence of the Tidal app. In summary, the Samsung Q70D represents a good continuation of the manufacturer's seventh series, which year after year is gaining – firstly, in quality, and secondly, in popularity.

Xiaomi, well-known as a giant in the smartphone market, has decided to compete for the attention of high-end tech enthusiasts by presenting a MiniLED backlit television. The S MiniLED 2025 model looks truly impressive on paper. An enormous 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 exceptionally well where motion smoothness 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 like ALLM and GameBar further enhances the gaming experience. Google TV on this television works as it should – quickly, smoothly, without unnecessary stutters, which we couldn't say about the model A Pro 2025. Additionally, with such an extensive app 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 quirks. The biggest issue is the algorithms managing the dimming zones, which can be quite irritating when watching movies in the evening. The performance of individual zones is overly noticeable in dynamic scenes, which can effectively distract our attention from the image. Problems also arise in more demanding HDR scenes despite the truly impressive brightness. Small bright elements often lose brightness, which spoils the effect that high-quality imagery should provide. The system is also not without its shortcomings – features that enhance images in lower-quality materials work unevenly, and some options in Google TV are poorly translated or even untranslated. Xiaomi S MiniLED 2025 has enormous potential, but in its current form, it seems underutilised. It is clear that Xiaomi wanted to do something really good, but a few significant shortcomings lead to a mixed final outcome. 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 issues with local dimming 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.

Samsung Q70D and its related models, such as Q77D and Q74D, use a VA panel, which should inherently provide decent contrast. Typically, it is several times higher than that of IPS/ADS screens that do not come equipped with an advanced local dimming system. As you can see, contrast results are quite varied, which is caused by the unevenness of the panel. Therefore, we might sometimes get good contrast, and other times it can be significantly worsened, but generally, it remains fairly consistent, aside from light bleed. Let’s take a look at the film scenes we prepared from "Oblivion" and "Revenant." As we can see, in the first one, the lights are well separated, which is a positive phenomenon, as the visibility of details in bright areas in further tests should be equally good. What stands out the most here is the unusual oversharpening of the smoke visible under the light and the navy black in the background. In the frame from the second film, the first thing that stands out is the unevenness of the backlighting of our piece. This was significant and strongly affected the perceived image. Nonetheless, the details in the film were well visible.

Xiaomi S MiniLED is one of the most affordable televisions with MiniLED technology available on the market. The model we tested, sized at 55 inches, is equipped with as many as 308 local dimming zones, which is impressive for such a price. Additionally, it features a VA panel, which inherently offers significantly better contrast than IPS panels. On static test screens, the television performed excellently, achieving an impressive contrast ratio of 182,000:1 in the film Oblivion. Blacks were deep, and details in both bright and dark areas of the image were clearly separated. However, in more demanding scenes where the image is dynamic, the situation begins to complicate.

Where lies the problem? The main cause is the local dimming algorithms. Although on static images, their effects are promising, during movie playback – which reflects the television's natural working conditions – they operate too aggressively. In dynamic scenes, like those from the tested film, one 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 fantastic contrast on paper, in practice, the effect is less satisfying. The aggressive operation of the algorithms ruins the perception of dynamic scenes, making the television perform average in this category. This is a good example of how MiniLED technology requires not only a good specification but also adequate optimisation.

The brightness that the Samsung Q70D can offer is at a rather average level, although it cannot be said that the HDR effect will not be noticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR content. As was the case in the paragraph about contrast and black levels, we can also observe here that the first scene, featuring a bright sunny sky and a darker foreground, has the lowest luminance of those measured. The result, which can be considered very good for this price range and display class, is that one. In a scene where we see a large light source filling a significant portion of the frame, the brightness of the TV is at its highest, reaching nearly 500 nits. However, it is worth noting the rather low coverage of the wide DCI-P3 colour gamut, which sometimes results in noticeable shortcomings in the colour reproduction. Additionally, users can enjoy rich colours and high precision in rendering shades, making movie screenings a unique experience. It is also worth mentioning that the Q70D Samsung panel performs excellently in eliminating blur during dynamic action scenes, which enhances the viewing comfort of sports broadcasts or games.

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 best factory mode in Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before the calibration process, it had several flaws that effectively hindered the presentation of the director's intentions. In both SDR and HDR material, the white balance was dominated by red and green colours. As a result, there was a characteristic yellow tint on the image, which caused whites to appear yellowed and skin tones to be noticeably too warm. The reduced gamma in standard colour palette materials caused a significant drop in contrast, which was already not the highest. This led to the highlighting of details in the blacks, but also to clipping in brighter scenes. In this case, the EOTF curve proved to be much better and only brightened those scenes with quite low luminance. This was clearly visible in the section where we measured the maximum brightness of the television in HDR materials. At that time, a shot from the film "Billy Lynn" appeared unnaturally bright and lacking depth.

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.

Fortunately, Samsung provides a wide range of calibration tools in all its TVs, including 2- and 20-point grey scale adjustments and advanced CMS. As a result, we were able to significantly improve the quality of SDR and HDR content. The vast majority of errors have been corrected, and the image that the Samsung Q70D now delivers is definitely much closer to the reference. Higher deltaE errors in wide dynamic range content primarily result from the display's insufficient luminance.

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.

Considering how important lighting is in films and series, the overlapping structures and fluidity of tonal transitions constitute an extremely significant element in assessing image quality. The colour grading on the tested television is at quite a decent level. It cannot be said that it is outstanding, but it is not bad either. We assess it as acceptable. Brighter scenes perform best here, demonstrating the least amount of choppiness. In scenes recorded in darker settings, slight shortcomings in grading can already be noticeable, although it is not an issue that would cause discomfort while watching. This may be disturbed by the leaking backlight, which is clearly visible in the last image.

The fluidity of tonal transitions in Xiaomi S MiniLED 2025 looks very good. Even in the theoretically most challenging scene with red water, the television performs excellently – we did not notice any major issues. Minor imperfections occur in scenes like Kingsman or The Martian, where you can see subtle colour blending. 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.

The function responsible for improving gradation is named "Noise Reduction" in the menu. As we have confirmed, it is worth enabling as it has a beneficial impact on tonal transitions. More importantly, it does not negatively affect film grain or fine details, which sometimes the competition "offers" us.

The image scaling on Samsung Q70D should be rated as average. The manufacturer does not aim to artificially sharpen the image, but rather to keep it naturally softened.

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.

Samsung Q70D is the first model in the manufacturer's portfolio with a 120Hz panel. As a result, its motion smoothing features are more advanced than those in lower-tier models. In the menu, we find three functions responsible for improving fluidity. They are "Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We'll discuss the third one later. The first function enhances sharpness in motion, while the second adjusts the level of smoothing. The smoothness enhancer in Samsung Q70D works satisfactorily, and each setting makes a noticeable difference. Therefore, those who dislike the characteristic stuttering of films or who passionately watch sports will be able to achieve their preferred level of smoothness. In the image, we present a setting with slight smoothing, without the soap opera effect.

The panel used in Samsung Q70D has a fairly good response time for this type of display. Of course, it won't deliver an image as sharp as a proverbial razor, but at this price point, it is a recommended choice for all kinds of sports.

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 tested television is equipped with four HDMI 2.1 ports. Interestingly, all of them have a bandwidth of 40 Gbps; however, during the testing process, we did not observe any negative effects associated with this situation. More importantly, Samsung Q70D supports all features stemming from the aforementioned standard. This news will surely delight all gamers, as it means that whether using a console or a PC, we can expect the highest possible comfort during gameplay. Given the standard absence of Dolby Vision HDR for this manufacturer, it is significant that the HGIG mode has been implemented correctly and there are no issues with setting up the calibration chessboard. We particularly note that Samsung is the only manufacturer to allow gaming with the smoothness enhancer switched on, without significant degradation. This means that titles running at 30 fps will be perceived like those with native 60 frames per second.

Samsung, as one of the first manufacturers, introduced the Game Bar to its televisions, which has since been consistently refined. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

In summary: Samsung Q70D will perform excellently both with consoles and with computers. All functions worked brilliantly, and there were no issues with them. The ability to enable the smoothness enhancer without significant increases in input lag is a true gamechanger.

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.

Results of latency on the Samsung Q70D are at a high level, regardless of the signal or resolution. All gamers will certainly appreciate the manufacturer's efforts, which allow a game running in 4K 120 Hz with HDR to have only 7 ms of latency, which is practically unnoticeable even in online gaming. It's worth adding that lag with the motion smoother turned on roughly doubles, which still means very comfortable gaming in this case.

Input lag in Xiaomi S MiniLED 2025 is one of its biggest advantages. 8 ms for 120 Hz content and 17 ms for 60 Hz are simply outstanding results that will satisfy even the most demanding gamers. Moreover, 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 lovers of high-quality HDR gaming experiences.

After connecting the television to the computer and wishing to use it as a monitor, we can expect a low input lag of 13 ms, which is practically unnoticeable on the mouse-screen-eye line. Thanks to the correct implementation of chroma 4:4:4, the readability of fonts is at a high level, so you can confidently connect Samsung Q70D to your computer as a monitor and expect a comfortable experience with text.

The subpixel layout is BGR, which does not negatively affect the use of the television as a monitor. However, as operating systems are not adapted to this type of subpixel format, it may cause slightly less distinct contours. This is, however, something practically negligible, and only a handful of people may notice it.

Xiaomi S MiniLED 2025 is a good choice if you need a TV for computer work. The fonts are very clear thanks to 4:4:4 chroma support, making it ideal 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.

Due to the VA panel, the performance of Samsung Q70D in terms of viewing angles is its Achilles' heel. Even a slight shift off-axis leads to a significant loss of contrast and a substantial degradation of colours.

In terms of viewing angles, Xiaomi S MiniLED 2025 is not impressive. This is a typical problem with VA panels, which struggle without additional coatings to widen viewing angles. The image begins to lose quality when watching the TV from the side – colours fade, and contrast significantly drops. However, the advantage of VA panels is their much better contrast compared to IPS panels, which in turn win when it comes to wider viewing angles. This is a classic compromise where one has to choose between better blacks and a more universal image seen from different spots in the room.

The satin finish of the panel in the Q70D allows for quite good performance in a well-lit room. It is worth noting that reflections do not spread beyond their source, and thus do not bleed onto the rest of the panel. We also commend the maximum brightness of the TV in SDR content, which is 450 nits, allowing for comfortable content consumption during the day.

Xiaomi S MiniLED 2025 is equipped with a satin finish on the display, which moderately handles glare reduction. On the screen's surface, you can see light reflections, which may be somewhat distracting in bright rooms. However, the key element that saves this television in daytime use is its brightness. With a value of 841 cd/m², the screen performs flawlessly even in very sunlit interiors. This is more than enough to comfortably watch television, movies, 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 excels.

The operation of Samsung Q70D is managed by the proprietary Tizen system. This is fairly well-known software, as the manufacturer has been developing it in their TVs for quite a long time. Its main advantage is smooth operation and a lack of significant stutters, which we can confirm through conducted tests. The biggest downside, however, is its closed nature. Although the app store is quite extensive, we are still dependent on the grace or displeasure of the manufacturer. Therefore, we will not be able to install missing items, even from a USB drive. A perfect example of this is this year's discontinuation of support for the Tidal app. On the other hand, a benefit, especially for Apple device users, is the implementation of AirPlay functionality, which allows for easy screen mirroring from a device to the TV. Fortunately, Samsung also provided the option to connect a keyboard and mouse for much quicker navigation through the TV menu. It’s worth mentioning that the manufacturer has thankfully included a remote that connects via Bluetooth this year, which often wasn't the case in the past. The Tizen system has one more advantage. It integrates very well with external devices, such as the NC+ decoder or soundbars. The connection process is very quick and does not require special skills.

In summary: The Tizen system is very efficiently functioning software, which is certainly a strong advantage of the TV. While more advanced users may complain about the lack of something like KODI, the rest will be satisfied.

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 everyday use of the TV. 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 TV but also ask for the weather forecast or set a reminder for the next day. Unfortunately, we noticed during testing that some functions have trouble translating into Polish, which can be annoying, especially for those less proficient in navigating the settings. Despite this, the overall impression is very good, and minor shortcomings can be improved in updates.

The device handles connectivity well. Wireless connections with Windows computers or Apple devices run smoothly, and thanks to Bluetooth, we can easily connect headphones, keyboards, or other accessories. The remote 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 might miss the recording functions from tuners or the PiP (picture in picture) option. This somewhat limits the possibilities, but for those focusing on streaming and modern features, it won’t be a major issue.

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

The built-in player Samsung Q70D is a significant advantage. It handled nearly all video and audio files prepared for the testing process exceptionally well. The only exceptions in this regard are of course the Dolby Vision format (which is not surprising) and less popular codecs. Additionally, it is worth noting the support for Polish characters and the ability to change font colours as a positive aspect. However, it struggles more with photo formats, as it only supports JPEG among the popular ones. There's definitely a lack of formats like PNG or Apple's HEIC here.

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

Fortunately, the presence of the Google TV system provides a way to easily work around this limitation. It allows for the installation of alternative file playback applications that handle Polish characters and offer significantly more advanced options. As a result, the limitations of the built-in player are not as burdensome as they may seem.

The built-in audio system Samsung Q70D, due to its slim design, is not among the most outstanding. Overall, it's fairly balanced, although we wouldn't recommend cranking up the volume to levels higher than 2/4 of the scale. However, if we have a home theatre system, there is a range of codecs available, and we can enjoy the presence of the most important ones, namely DTS-HD Master Audio and Dolby Atmos.

Xiaomi S MiniLED 2025 sounds really pleasant, and even offers a light bass, reminiscent of the sound known from the lower model, the A Pro 2025. The sound is well balanced, making watching movies or listening to music comfortable, even without additional audio equipment. Interestingly, the television seamlessly supports audio formats like Dolby Atmos and the less common DTS:X. This allows you to connect a home theatre system or soundbar and enjoy spatial sound without any difficulties. A nice addition is also the presence of a standard speaker jack connection.
