Our verdict

LG G4 is a strong contender for being the best television of 2024. Thanks to the combination of OLED black and MLA technology, we will get an incredibly dynamic and vibrant image that will surely captivate us completely. LG G4 is also proof that televisions equipped with an OLED panel supported by MLA technology are indeed suitable for viewing in bright rooms. The operating system, while not as open as the competition, allows for many possibilities. Its greatest advantage is the well-known remote with a cursor, which makes controlling the unit (in our opinion) one of the most convenient on the market. Factory colour reproduction, although not at a high level, after undergoing calibration, can be considered almost reference-quality, providing a truly cinematic image. No wonder post-production studios choose televisions from this manufacturer. They uniquely offer such a deep capability to adjust the image, thanks to 3D LUT calibration. It seems that the biggest (and perhaps only) drawback of this television is the tonal transitions, which, while far from perfect, cannot be said to detract from the viewing experience. The remedy is provided by the manufacturer themselves, and enabling the "Smooth Gradation" function will remove the vast majority of any choppiness. LG G4 also performs exceptionally well when watching all kinds of sports or other dynamic scenes. The motion smoother is incredibly advanced and allows for adjustment of smoothness to suit individual needs. Thanks to HDMI 2.1 ports with full functionality and the manufacturer's attention, the tested television will find its place in the homes of many passionate gamers. Each of the essential features works flawlessly, and the low input lag in every mode is very pleasing. In summary, LG G4 is an incredibly versatile television, allowing for entertainment in excellent quality both at night and during the day.

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.

Halo effect and black detail visibility:

LG G4, with its OLED panels produced for over 10 years, delivers perfect contrast, black levels, and detail reproduction in the darkest scenes. It's worth noting that the panel itself is equipped with MLA (Micro Lens Array) technology, which LG showcased just a year ago with the launch of its predecessor. The use of an organic panel not only allows for achieving pitch-black blacks but also provides extraordinary immersion and a three-dimensional effect in the image, which is hard to find even in the best Mini LED TVs. Such image quality is closely linked to OLED panel technology, as each pixel is controlled by an electrical impulse rather than shading filters on the panel. Therefore, if we want to achieve black, the pixel is simply turned off. This is very evident in test images, where the spotlight provides high brightness while being perfectly separated from each other. The situation remains unchanged in the challenging scene from "Sicario 2," where no imperfections from zone dimming can be seen, which we might encounter in LCD TVs.

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.

LG OLED G4

LG G4 guarantees an incredibly vibrant HDR effect, placing the television firmly at the top of the rankings. The highest model in the manufacturer's 2024 portfolio, equipped with the second generation of microlens technology (MLA), has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product of the Korean manufacturer may fall short compared to LCD televisions with Mini LED backlighting is during a full-screen scene featuring a lot of white. If we were to disregard the latter scene, the average result would be even higher. It's also worth mentioning scenes with very fine details, where each one shone at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 color space ensures that HDR materials are more engaging than ever before.

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.

After calibration

The best factory mode in terms of colour reproduction was "Filmmaker". This is the one we used during our tests. Let's check how its characteristics looked before the calibration process. Taking a closer look at the white balance first, we can notice a significant dominance of red and green colour. As a result, the image had a warm yellow tint. This is the kind of characteristic we usually observe in "Cinema", "Filmmaker", or similarly named modes. The effect of such a colour balance was clearly visible in both SDR and HDR content, which, after switching from "Standard" mode, was distinctly yellowed. Now let's move on to two graphs that are responsible for brightness characteristics, and consequently, image contrast. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, the midtones and bright whites were represented very accurately, however, it noticeably lost the darkest details which blended into a black patch. On the other hand, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. There was also an issue with the colours themselves as seen on the "ColorChecker" graph since they were noticeably undersaturated.

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.

Color reproduction after calibration

9.5/10

8.4/10

The manufacturer has been implementing extensive support for the calibration process in their LG televisions for many years. Therefore, we used 2- and 20-point grey scale adjustments along with an advanced CMS (Color Management System) and got to work. As you can see, thanks to the procedure carried out, each of the parameters has significantly improved. The use of tools has resulted in extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and proper colour saturation. Thus, we have maximised our approach to the reference image, or the one that the film director saw on the preview monitor. It is worth noting that the LG G4 televisions are the only ones that allow for even deeper intervention in image quality due to the capability to calibrate with 3D LUT matrices. However, this solution is recommended only for post-production or graphic studios.

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.

Smoothness of tonal transitions

6.2/10

8/10

The tonal transitions presented on LG G4 are not among the top performers. Each scene played from a BluRay disc with 10-bit HDR exhibited noticeable choppiness in the colour transitions. This was particularly evident in the case of the film "The Green Knight," where issues related to posterisation were especially pronounced. This effect could also be observed in films with moderate to high brightness, such as "The Martian" or "Kingsman," which is rarely seen in televisions (especially of this class), which took us by surprise. Such results suggest that in scenes with low luminance and a lot of black, this issue will be troublesome, even for a layman.

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.

Image without overscan on the SD signal

The tested television did not perform well with content rich in tonal transitions, resulting in a strong posterisation effect. However, there is a partial remedy for this ailment. The manufacturer has equipped the LG G4 with a smoothing system called "Gentle Gradation," which we can apply at three levels: Low, Medium, and High. Each of these options guarantees quite high smoothing effectiveness on bright colours, though low on darker ones. We recommend primarily using the first one due to the fact that the other two interfere with directorial intentions, removing film grain.

When watching lower-quality content, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, attention should be paid to the jagged edges of fine details and minor issues around characters, such as the creation of a halo effect, which occurs due to the sharpening imposed by the LG G4 even when the slider is set to the lowest value, which is 0. It is worth noting that this is a change in relation to the LG G3, which did not impose such strong image sharpening, even when the appropriate slider was set to position 0.

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

Image scaling also comes across as average. There’s slight jaggedness, especially on thin elements like branches, and text can be a bit ragged. It may not be overly bothersome, but a more discerning eye will certainly catch these imperfections. Overall, most users should be satisfied with the scaling and smoothing quality, but the TV may not satisfy those who expect perfection in every frame.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible by connecting the LG G4 to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with high motion dynamics. For those who require high fluidity of image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range from 0 to 10, with each increment affecting the degree of smoothing, so everyone can find their sweet spot.

The LG OLED G4 panel features an average response time of 0.78 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable by LCD televisions, which have response times of even several milliseconds. This is clearly visible in the "UFO Test" images, showing the absence of any trailing blur behind the object. Furthermore, the LG OLED G4 test showed that the television offers the ability to precisely adjust motion smoothing functionality, allowing users to choose the ideal level of image interpolation. We particularly appreciated this during fast-paced action in video games, where the LG G4 performed exceptionally well, minimising any blurriness. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sports or movie scenes.

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 LG G4 television supports all features that make up the HDMI 2.1 standard. During testing, each feature activated without any issues, which allows us to consider the television as designed for gaming. Its performance will certainly be appreciated by both console users and those connecting the LG G4 to a computer. It’s also worth mentioning the proper implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels beyond the maximum luminance of the LG G4 will correctly map tones, keeping the game image true to the original.

A nice touch is the presence of a special GameBar that we can bring up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, turning on VRR technology does not degrade contrast, which is often a problem in televisions with local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emissiveness. As a journalistic note, we will only mention a slight grey flicker, which, however, is somewhat normal when VRR is enabled.

In summary, the LG G4, like practically all OLED televisions, is an ideal product for all kinds of gaming and online competitions. With full HDMI 2.1 ports with a complete bandwidth of 48 Gbit, features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will bring a lot of joy.

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.

The input lag of the LG G4 is impressively low in every scenario. Even the most dedicated gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is just 5 ms. It's also worth noting that the lag at the same settings, but with Dolby Vision HDR enabled, remains unchanged, which is not as obvious with the competition. Therefore, it deserves the highest rating and recommendation.

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.

LG G4 paired with a PC performs excellently, thanks to an incredibly low latency of just 5 ms, which is practically instantaneous response between the mouse, eye, and screen. A crucial aspect while working on the screen is the readability of text, which is very good in the case of the tested television.

The RWBG pixel arrangement has no significant impact on the display of fonts or letters, which is a considerable advantage over Samsung's QD-OLED matrices. Users of both Windows-based PCs and macOS will surely be pleased with the performance on the tested LG G4 television.

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.

Viewing angles

The undisputed advantage of OLED screens equipped with MLA technology is their performance when viewing from various angles. To the naked eye, there are no noticeable changes, regardless of where we are watching from. This type of screen maintains consistent brightness, saturation, and white hue, unlike LCD matrices or OLEDs without micro-lens technology (MLA). The only matrices that can match them are those produced by Samsung Displays, using quantum dots, namely QD-OLED.

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 glossy coating of the display in LG G4, although it may sound like a downside, is actually quite the opposite. Thanks to it, the LG G4 television maintains very high efficiency and effectively suppresses all reflections, "holding" them only at their source. It's also worth mentioning the quality of black during the day, which in the case of WRGB displays produced by LG Displays is outstanding. OLED MLA displays, despite their many advantages, are somewhat inferior in this case, but still better in the context of competition from Samsung, whose QD-OLED displays fade under light. The combination of brightness at around 500 nits and the glossy coating allows for daytime viewing of the television, unless the user has a living room with large glazing.

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.

LG uses the well-known proprietary system WebOS, which has been around for many years. The system offers virtually all the essential applications, and those that are missing can be counted on one hand, such as CDA or KODI.

WebOS also provides the highly valued ability to perform operations using a cursor that appears when the remote control is moved. The convenience of such a feature is invaluable when entering queries or passwords for portals. WebOS, like most systems, also supports functions such as screen mirroring, AirPlay, voice search in Polish, and the ability to connect headphones via Bluetooth. On a more practical note, WebOS allows us to use both headphones and the TV speaker LG G4 simultaneously, which will certainly be a significant advantage for those with hearing disabilities. Among the more interesting features, particularly appreciated by sports fans, is the option to enable an alert for upcoming matches, ensuring that we never miss a broadcast. The home panel also deserves praise, allowing for control of all smart devices connected to the home network. For example, the end of a laundry cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, although less known and with some limitations compared to Android TV, offers stable and fast operation and supports most features that users might need. It is a solid solution for those looking for a simple and effective operating system in a television.

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 default file player on the LG G4 performs quite well with most photos, although it's surprising to find a lack of several equally popular ones. It can successfully play videos recorded in virtually all the most popular formats, including Dolby Vision. The only codec that the G4 cannot play is H.266 VVC, although this is currently quite rarely used. However, it's important to note the supported photo formats, of which there are only two: JPEG and PNG. Users of Apple phones may feel disappointed by the lack of support for the HEIC format, which is the default format when taking photos. The remedy for this is to use the built-in AirPlay feature. Lastly, we should also mention the lack of support for TXT subtitles.

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 assessment of sound quality is always subjective. However, we must give credit to LG G4 for maintaining a fairly good level of sound clarity. The biggest drawback of the built-in audio system in the television is the low bass range. However, it’s important to look at this from a different perspective — anyone opting for this television will likely have a home theatre system. The key in this case will be broad support for audio codecs, including 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.
