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

Samsung Q70D performed in the test just as it should for its category – very well. The strongest points of the television are undoubtedly its efficiency when using a console and the colour reproduction after undergoing the calibration process. The former will certainly not allow gamers to remain indifferent to the range of benefits that Samsung Q70D can offer, and there are indeed many, including this almost exclusive feature for the manufacturer’s units – the ability to smooth out gameplay while maintaining a reasonable input lag, which allows 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 correctly set up, is on par with games using Dolby Vision. One should also not overlook the ease of pairing the television with the Canal+ decoder, which is not such an obvious advantage, but we know that many people struggle with this issue. Staying on the topic of television, it must be acknowledged that the Samsung Q70D offers very good brightness in SDR materials for its price range, making daytime viewing more than comfortable. A downside for the tested television has to be the lack of Dolby Vision, which would have greatly enhanced the maximum brightness of the Samsung Q70D. One should also not overlook the construction flaws of the device, which may (though not necessarily) lead to light bleed, which can be noticed in dark conditions on less bright scenes. What cannot be taken away from Samsung Q70D is the fact that it features one of the better motion smoothing technologies in its price range, which works excellently in the context of sports events or fast-paced action scenes. The system that operates the television runs very smoothly, and the only complaint one might have is the lack of the Tidal app. In summary, the Samsung Q70D is a good continuation of the manufacturer's seventh series, which year after year gains – both in quality and popularity.

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.

Samsung Q70D and its related models, such as Q77D and Q74D, utilise a VA panel, which in itself should provide decent contrast. Typically, it is several times higher than in IPS/ADS screens that are not equipped with an advanced local dimming system. The contrast results, as you can see, are quite varied, which is caused by the non-uniformity of the panel. Therefore, at times we can achieve good contrast, whereas at other times it is significantly degraded, but generally fairly consistent, not counting light leakage. Let’s take a look at the film scenes we prepared from the films "Oblivion" and "Revenant". As we can see, in the first one, the lights are well separated from each other, which is a positive phenomenon, as visibility of details in the whites in further tests should be equally good. What stands out the most here is the unusual over-sharpening of 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 uneven backlighting of our scene. It was quite significant and heavily affected the perceived image. Nevertheless, the details in the film were well visible.

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 brightness that the Samsung Q70D can offer is at a fairly average level, although it cannot be said that the HDR effect will be unnoticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR materials. As was the case in the paragraph about contrast and black levels, this time we can observe that the first scene, featuring a bright sun and a dark foreground, possesses the lowest luminance among the measured ones. The result, which can be considered very good for this price range and class of display, is the latter. In a scene where we see a large light source filling a significant part of the frame, the brightness of the television is at its highest, reaching nearly 500 nits. It is worth noting the quite low coverage of the wide DCI-P3 colour gamut, which occasionally results in noticeable gaps in the colour palette. Additionally, users can enjoy rich colours and high precision in shade reproduction, making movie screenings a special experience. It is also worth noting 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 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.

The best factory mode on the Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before calibration, it had several flaws that effectively prevented it from conveying the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green. As a result, there was a characteristic yellow tint on the image, causing white to appear yellowed and resulting in skin tones that were noticeably too warm. The lowered gamma in standard colour gamut materials resulted in a significant drop in contrast, which was already not the highest. This caused detail in the blacks to be accentuated but also led to overexposure in brighter scenes. The EOTF curve, in this case, proved to be much better and only brightened those scenes with relatively low luminance. This was perfectly evident in the section where we measured the television's maximum brightness in HDR materials. At that point, the frame from the film "Billy Lynn" was unnaturally bright and lacking in 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 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.

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, including 2-point and 20-point grey scale adjustment as well as advanced CMS. This allowed us 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 generates is definitely closer to the reference. Higher deltaE errors in wide dynamic range content are primarily due to the display's insufficient luminance.

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.

Considering how important lighting is in films and series, the overlapping structures and the fluidity of tonal transitions constitute an extremely significant element in assessing the quality of the image. The colour grading in the tested television stands at a fairly decent level. It cannot be said to be outstanding, but it is also not bad. We assess it as adequate. Brighter scenes perform best here, showing the least amount of stuttering. In scenes recorded in darker settings, slight deficiencies in grading can already be noticed, although this is not an issue that would cause discomfort while watching. This may be disrupted by the bleed of the backlighting, which is clearly visible in the last image.

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.

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

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

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.

Samsung Q70D is the first model in the manufacturer's portfolio featuring a 120Hz panel. Consequently, its motion smoothing functions are more advanced than those in lower-tier models. Within the menu, we find three functions responsible for improving smoothness: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We will discuss the third one later. The first function is responsible for sharpness in motion, while the second adjusts the level of smoothing. The smoother in Samsung Q70D performs satisfactorily, and each setting brings noticeable changes. Therefore, those who dislike the characteristic juddering in films or are avid sports viewers will be able to achieve a personalised level of smoothing. In the picture, we present a setting with slight smoothing, without the soap opera effect.

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

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 tested television is equipped with four HDMI 2.1 ports. Interestingly, all of them have a bandwidth of 40 Gbps; however, during the conducted tests, we did not find any negative effects related to this state of affairs. Moreover, and more importantly, Samsung Q70D supports all functions resulting from the aforementioned standard. This news will surely please all gamers, as it means that whether using a console or a PC, we can count on the highest possible comfort during gameplay. Given the typical absence of HDR Dolby Vision for this manufacturer, it is significant that the HGIG mode has been correctly implemented and there is no issue with setting the calibration checkerboard. We particularly note that Samsung, as the only manufacturer, allows gameplay with the smoothener turned 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 it has consistently refined since then. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

To summarise: Samsung Q70D performs excellently both with a console and a computer. All functions worked perfectly and there were no issues with them. The ability to enable the smoothener without a significant increase in input lag is a true game changer.

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.

The latency results in Samsung Q70D are at a high level, regardless of the signal or resolution. All gamers will certainly appreciate the manufacturer's efforts, which allow for a game running in 4K 120 Hz with HDR to have a mere 7 ms latency, which is virtually unnoticeable even in online games. It is worth adding that the lag with the smoothness enhancer switched on increases by about twice, which still means very comfortable gaming in this case.

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.

After connecting the television to the computer and wanting to use it as a monitor, we can expect a low input lag of 13 ms, which is practically unnoticeable along 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 one can confidently connect the Samsung Q70D to the computer as a monitor and anticipate comfortable work with text.

The subpixel arrangement is BGR, which does not negatively impact the use of the television as a monitor. However, since operating systems are not adapted to such a subpixel format, this may cause slightly less clear outlines. Nevertheless, this is practically negligible and only a handful of people may notice it.

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.

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

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 satin finish of the panel in the Q70D allows for quite good performance in a strongly sunlit room. It is worth noting that the reflections do not extend beyond their source, thus not spilling over onto the rest of the panel. We also commend the maximum brightness of the television in SDR materials, which is 450 nits, allowing for comfortable content consumption during the day.

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 operation of the Samsung Q70D is powered by the proprietary Tizen system. It is quite a well-known software, as the manufacturer has been developing it in its televisions for a really long time. Its main advantage is smooth performance and the absence of significant stutters, which we can confirm through conducted tests. The greatest downside, however, is its closed nature. Although the app store is quite extensive, we are still at the mercy of the manufacturer. Therefore, we will not be able to install missing items, even from a pendrive. A perfect example of this is this year's discontinuation of support for the Tidal app. On the other hand, a benefit, especially for users of Apple equipment, is the implementation of AirPlay, which allows for easy mirroring of content from a device to the television. Fortunately, Samsung has also provided the option to connect a keyboard and mouse for much quicker navigation through the television's menu. It is worth mentioning that the manufacturer has luckily included a remote that connects via Bluetooth this year, which often did not occur 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 any special skills.

In summary: The Tizen system is very smoothly functioning software, which is certainly a strong advantage of the television. Although more advanced users may complain about the lack of at least 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 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 built-in player Samsung Q70D is one of its major advantages. It handled almost all video and audio files prepared for the testing process excellently. The only exceptions in this regard are, of course, the Dolby Vision format (which is not surprising) and less popular codecs. Additionally, credit should be given for the support of Polish characters and the ability to change font colours. However, it performs worse with photo formats, as it only supports JPEG among the popular ones. There is definitely a lack of formats such as PNG or Apple's HEIC.

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 audio system Samsung Q70D, due to its slim design, is not among the most outstanding. The overall sound is fairly balanced, although we wouldn't advise increasing the volume above 2/4 of the scale. However, if we have a home cinema system, a number of codecs await us, notably featuring the most important ones, namely DTS-HD Master Audio and Dolby Atmos.

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.
