Compare: LG OLED C4 vs XIAOMI A PRO 2025

LG C4 is a television that will likely have no competition in its price range for many users. Thanks to the wide options for purchase, it will appeal to those looking for a TV strictly for movies and series, as well as for gaming. The advanced WebOS system and a remote that works like a mouse will certainly make everyday use much easier and ensure that we will likely stick with this brand for a much longer time. The OLED panel implemented by the manufacturer, resulting from over 10 years of history, shows that it has not yet said its last word. Brightness results in HDR material are very solid and can display an incredibly dynamic and deep image. Here, it’s worth mentioning the excellently implemented dynamic tone mapping feature, which makes HDR10 images look almost as good as Dolby Vision. And if we’re talking about fidelity to artistic vision, we can't forget about how calibratable LG TVs are, allowing for a great deal of freedom for the calibrator and classic calibration for home users, as well as 3D LUT for professionals. However, if we are looking for a gaming TV, then the LG C4, like most of the manufacturer’s OLED TVs, will be the ideal choice. With the implementation of HDMI 2.1 ports and the full use of their potential, we can enjoy extremely smooth gameplay with all the benefits, such as VRR, ALLM, FreeSync, or G-Sync. Of course, the panel, which has a maximum refresh rate of 144 Hz and an advanced smoothing technology, will also allow for very smooth and sharp images during broadcasts of various sporting events. It’s hard not to give a high rating to LG OLED C4, as it's difficult to find a TV in a similar price range with such advanced features among the competition.

Xiaomi A Pro 2025 is an affordable QLED model that works well as a basic television at home. The Google TV operating system deserves special mention. Thanks to it, you can easily use apps like Netflix or YouTube. The interface is clear and easy to navigate, and the voice search capability in Polish ensures that we can quickly find the content we are interested in. The picture quality of the A Pro 2025 is sufficient for everyday TV watching or movies. Smooth tonal transitions and the enhancement of older materials make even lower resolution content look good. However, the screen brightness may disappoint in very sunny rooms – here, the TV performs moderately, but it fares much better in a darkened room. The television is more suited to occasional gaming. The low input lag provides quick response times, which is important for dynamic games. However, the 60 Hz panel and lack of more advanced features may not appeal to gamers looking for perfect image fluidity. On the other hand, A Pro 2025 may be sufficient for those who play from time to time. Not everything works perfectly. When connecting the TV to a computer, the fonts are hard to read, which can be an issue when working with text. The Google TV system itself can be a bit slow, which sometimes makes it difficult to switch between apps quickly. Xiaomi A Pro 2025 is a simple and functional TV that is good for everyday TV watching and using apps. It has its drawbacks, such as average brightness and issues with font readability, but at this price, it offers a lot. It’s a good choice for those looking for budget equipment for basic uses.

LG OLED C4, as the name suggests, uses an organic panel of its own production. This series definitely belongs to one of the most recognisable on the market. Over 10 years of experience in building self-emissive panels has allowed for the refinement of each subsequent design, with the models from the 2024 range being the quintessence of this process. Of course, the use of this type of screen enables the achievement of flawless contrast and blacks, allowing viewers to immerse themselves in the world created by the director. This is possible thanks to the OLED panel, characterised by the absence of conventional backlighting, which instead allows current to pass through organic pixels. This permits super-accurate image control, thereby eliminating issues such as dimming of delicate fine details or the halo/blooming effect. Looking at both of our test scenes, we can notice two things: perfect light separation and a plethora of details in the movie "Sicario 2".

Xiaomi A Pro is equipped with a VA panel, which inherently offers distinctly better black depth and colour intensity compared to IPS panels, especially in darker conditions. Based on the tests conducted, the contrast measurement tool indicated a maximum value of around 6000:1. This is a solid result, ensuring good separation of image elements in darker scenes. An example is the film Oblivion, where the TV excelled at separating bright and dark areas, enhancing the visual effects. Unfortunately, the TV does not support local dimming technology, which is an obvious fact in this price range. This particularly stands out in tougher scenes, such as those from the film Sicario 2. In such moments, the black loses intensity and starts to resemble a navy blue shade. The lack of dynamic dimming of image segments means that details that should be deeply dimmed remain slightly illuminated.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

In the HDR category, the television Xiaomi A Pro performs, to be blunt – poorly. In ideal conditions, it offers brightness at around 250 nits. This is a weak result; however, in this price range, many competing models offer similar or lower values. Such brightness is too low to fully capture the potential of HDR content. In practice, this means that the image lacks the proper depth and intensity expected from high-quality HDR. These values are more characteristic of Standard Dynamic Range (SDR), which means the true HDR effect remains out of reach for this model, and scenes that should stand out with spectacular brightness and contrast seem flat and lacking in vibrancy. However, for its price, the television offers good coverage of the DCI-P3 colour palette at 92%, thanks to quantum dot technology (specifically PFS LED). This results in vibrant and saturated colours, which will appeal particularly to gamers and movie enthusiasts who appreciate richer hues and better colour reproduction compared to traditional televisions without this technology.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

The Xiaomi A Pro 2025 TV has been tested in movie mode, which offers the best colour reproduction straight out of the box. However, it’s worth noting that it is not without flaws. Analysing the white balance, one can see that the green values are in the negative. This phenomenon leads to some distortions in the shades of white, and at full white, the graph shows clear deviations. The high-contrast image results in inadequate tonal transitions in red, which negatively affects the quality of colour display. Generally, in the image below, it can be seen that the entire scenery before calibration takes on pink hues. Additionally, when analysing the gamma contrast, the graph is significantly below the value of 2.4, suggesting that the TV overly emphasises dark tones, while the brighter areas of the image may appear less pronounced. Furthermore, the EOTF curve shows a strong spike at the start, which can lead to a loss of detail in bright scenes and an unpleasant feeling of over-exaggeration. These aspects indicate the need for further calibration to achieve a more balanced colour reproduction and improve overall picture quality. Users who expect precise colour reproduction may need to take action to adjust the TV settings to achieve more realistic and natural visual results. In xiaomi tv a pro 2025, the factory colour settings in Xiaomi are average and may require calibration. After appropriate colour adjustment, the image gains a natural and vibrant colour palette, significantly closer to cinematic standards. It’s worth adding that the issue of inaccurate colour reproduction is typical for many TVs of this class, meaning it’s not a fault unique to the Xiaomi A Pro 2025 TV. For those who value perfect colour reproduction, professional calibration will be a key element that enhances overall picture quality.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

Now it’s time to check how the Xiaomi A Pro 2025 TV performed after calibration. The biggest beneficiary of this process is white balance. After calibration, all previous errors were corrected in both HD and 4K content, and most errors no longer fell significantly outside the value of "2". This means a much more balanced and natural colour reproduction, which certainly affects the viewing comfort. In terms of gamma, the drop has been greatly mitigated, resulting in a more consistent tone reproduction across various scenes. However, the EOTF curve has not improved significantly due to a lack of effective control over dynamic tone mapping. This limitation means that there are still some issues with detail reproduction in bright scenes, which can affect the perception of certain materials. Nevertheless, despite these minor shortcomings, the overall shape of the picture is definitely better after calibration. The TV has gained quality, and the improved white balance along with reduced gamma issues means that users can enjoy a more realistic and pleasant visual experience. Further adjustments to the settings could improve the picture quality even more, but already the TV is demonstrating its capabilities, meeting the expectations of many users.

The fluidity of tonal transitions in LG televisions has always been a rather sensitive issue, as the manufacturer, despite impeccable performance in other areas, has almost always struggled to get this right. The evaluation results for the fluidity of tonal transitions in the tested television were quite good, with issues mainly visible in darker scenes, such as the last two scenes. Interestingly, this is a significantly better result than the highest model from the manufacturer, namely the LG G4.

During the fluidity tests of tonal transitions in Xiaomi A Pro 2025, the gradation proved to be close to ideal. In most of the test sequences, there were no noticeable issues. Only in the scene with red water did very cosmetic imperfections appear, which, however, have no significant impact on the overall image quality. Both colour and grey gradients were reproduced with almost perfect precision, making this TV model a very good choice for those who pay attention to this particular feature of a television.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

How does the Xiaomi A Pro 2025 handle tonal transitions, especially with lower quality materials? Thanks to advanced digital processing, the colour contour removal feature works surprisingly well. We recommend setting this option to "Medium" – this way, the television significantly improves the smoothness of tonal transitions while avoiding excessive smoothing of other image elements, such as film grain.

In the case of the test shot with the model and numerous branches in the background, the Xiaomi A Pro 2025 showcased its capabilities in the context of digital processing. Adding artificial sharpness to this scene made the details of the model clearer, and her hair appeared more detailed. However, delicate contours appeared around the branches in the background, which were a result of digital intervention. While this enhances the overall impression of details, excessive sharpness can make some elements of the image seem unnaturally emphasised.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the 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 of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

Xiaomi A Pro 2025 offers a motion smoothing feature called "Motion Smoothing," which primarily works for films. It can be customised to favour either a more cinematic, film-like effect with visible frames or a smoother, theatrical image. This feature should satisfy those who intend to watch mainly films on it. However, gamers and sports fans may feel disappointed. The panel with a refresh rate of 60 Hz, typical for this price range, does not impress. Our "Ufo" test revealed some blurring. Those expecting better clarity for moving objects may be slightly let down.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.

Xiaomi A Pro 2025 offers several features useful for gamers, including Game Bar, which differs from the typical “dashboards” with interfaces found in other manufacturers. With this, users can quickly access game-related settings, which is convenient during intense gaming sessions. The TV also supports automatic low-latency mode (ALLM), meaning it automatically switches to a mode optimised for gaming, reducing signal delay. Unfortunately, it lacks support for HDMI 2.1, limiting the connection capabilities for the latest gaming consoles that may require higher bandwidth. Additionally, the TV does not support features such as VRR (variable refresh rate) or G-Sync, which are increasingly desired by gamers as they allow for smoother images and eliminate tearing. For these reasons, although Xiaomi A Pro 2025 has some features for gamers, in this price range, better options can be found that offer more advanced gaming solutions.

The latency time of LG C4 is remarkably low in every scenario. Even the most avid gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is only 5 ms. It's also worth noting that the lag at these same settings, but with Dolby Vision HDR enabled, remains unchanged, which is not so obvious with the competition. Therefore, it deserves the highest rating and recommendation.

Xiaomi A Pro 2025 delivers outstanding performance, regardless of resolution or HDR mode. With measurements as low as 15 ms, this TV ranks among the best in terms of responsiveness.

LG C4 combined with a PC works wonderfully, thanks to its very low latency of just 13.5 ms, which is practically instantaneous feedback between the mouse, eye, and screen. An extremely important aspect when working on a screen is the readability of text, which in the case of the tested TV is very good. However, it is worth noting that to achieve sharp fonts, you need to enable the passthrough option in the settings.

The RWBG pixel layout does not significantly affect the display of fonts or letters, which is a significant advantage over Samsung's QD-OLED panels. Users of both Windows-based PCs and macOS will surely be pleased with their experience on the tested TV screen.

In the category of collaboration with PCs, Xiaomi A Pro 2025 performs very poorly. The fonts are of low quality, and their display on the screen is often problematic. Dithering is ubiquitous; when zooming in on the fonts against a dark background, they are displayed in three colours, which is definitely eye-catching and can significantly hinder comfortable use of the device. Such issues can be a significant drawback for users planning to use the television as a computer monitor.

The undisputed advantage of OLED panels is their efficiency in the context of group viewing, meaning from various angles. LG C4 maintains very good contrast, colour saturation, and fidelity. Although this isn't a result of organic TVs supported by MLA technology, it's fair to say that anyone who purchased the device was satisfied with the results obtained. However, it should be noted that at sharp angles a slight greenish tint can be observed. This is a characteristic feature of WRGB panels from LG, without the aforementioned micro-lens technology, and unfortunately, there's nothing that can be done about it.

In the viewing angles category, Xiaomi A Pro 2025 with its VA panel simply performs poorly. While directly in front you can enjoy better blacks, the image loses quality from side perspectives. Our specialists found during the testing of the television that sitting a metre away from the device, the image on the right side is brightened and desaturated. However, moving a bit to the side improves everything, highlighting how significant the difference in image reception is depending on the viewing angle. All this makes the viewing experience in a larger group potentially less satisfying.

The maximum brightness of the television in SDR materials is 367 nits. For an OLED television, this is a very good result and allows for quite comfortable viewing during the day. It's worth noting two things. Thanks to the glossy coating of the panel, the light reflections are well held in place and do not spill over the rest of the panel. The second issue is the brightness of the screen when fully filled with white, oscillating around 220 nits, which is a remarkable result, as until recently, OLED televisions in this category could only boast brightness half as much. As a result, the conditions for watching, for example, winter sports will be very good.

Xiaomi A Pro 2025 presents itself as average. The panel coating is satin, which may help reduce reflections, but the suppression of glare is moderate. The brightness of the television is only 250 nits, which is relatively low compared to other models on the market. As a result, during sunny days or in brightly lit rooms, the image quality may suffer, and details may be hard to discern.

LG uses the well-known proprietary WebOS system that has been around for many years. The system offers virtually all the major apps, and the few that are missing can be counted on one hand, such as CDA or KODI. It's also worth noting that the modern web browser and the remote with a built-in mouse allow for convenient access to streaming services in this way, if there isn't a built-in app.

WebOS also features a highly praised ability to perform operations using a cursor that appears when the remote is moved. The convenience of this function is invaluable when entering queries or passwords for portals. WebOS, like most systems, also supports features such as screen mirroring, AirPlay, voice searching in Polish, and the ability to connect headphones via Bluetooth. On a more practical note, WebOS allows simultaneous use of headphones and the television speaker, which will certainly be a significant help for those with hearing impairments. One of the more interesting features, particularly appreciated by sports fans, is the ability to turn on an alert for an upcoming match, 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 wash cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, although less known and with certain limitations compared to Android TV, offers stable and quick performance and supports most functions that users may need. It is a solid solution for those looking for a simple and effective operating system in their television.

In the functionality category, Xiaomi A Pro 2025 stands out with the Google TV system, which is one of its biggest advantages. This allows users access to a wide range of apps and streaming services, significantly enhancing the convenience of using the television. The Google TV system also offers a voice assistant that facilitates navigation and allows for quick content searches without the need to dig through menus. One of the key strengths of this system is the ability to download virtually unlimited apps from the Google Play Store, enabling personalisation of the television according to individual needs. Users can install apps for streaming, gaming, and various tools, making the television a multimedia entertainment hub. However, it is worth noting that this model lacks recording functions and AirPlay, which may be disappointing for some users. Additionally, there are quite significant lags in the operating system, affecting the ease of use. On the positive side, it also features the ability to pair other peripheral devices via Bluetooth and a remote that does not require aiming at the screen, which significantly improves user comfort. Despite some shortcomings, Xiaomi A Pro 2025 has the potential to meet the needs of users looking for a modern television.

The default file player on LG C4 handles all photo resolutions exceptionally well. It successfully plays videos recorded in practically all the most popular formats, including Dolby Vision. The only codec that the C4 won't play is H.266 VVC, although this is currently rather uncommon. It's a pity that subtitles in .txt format are not supported. Attention should be paid to the supported photo formats, of which there are only three: JPEG, PNG, and, importantly for Apple phone users - HEIC. However, the tested television cannot be faulted for a lack of variety in audio files, which can be played without a compatibility warning.

Xiaomi A Pro 2025 offers a decent built-in media player that meets the basic expectations of users. However, the TV has its drawbacks and sometimes encounters issues with playing certain file formats, which can be frustrating. Fortunately, with access to Google Play Store, users can easily download alternative players that better meet their needs. In our test of the Xiaomi TV A Pro 2025, we demonstrated that its compatibility with applications is high, and additional media playback applications work flawlessly. It is also worth highlighting that the Xiaomi TV A Pro 2025 is equipped with the Android TV platform, enabling access to a wide range of applications and streaming services. Installing alternative media players enhances the overall functionality of the device and eliminates format compatibility issues. As a result, Xiaomi A Pro becomes a more versatile television that can meet the diverse expectations of users, even those with higher demands regarding media playback.

The audio system implemented in LG C4 is very well tuned, allowing us to experience strong bass as well as balanced mid and high tones. We can confidently say that in its price range, it's one of the better sounding televisions. However, we believe that those deciding to purchase the C4 will already have a dedicated audio set. The presence of DTS-HD Master Audio and Dolby Atmos codecs will also be significant.

When it comes to sound, Xiaomi A Pro 2025 pleasantly surprises, especially considering its price. The sound quality is really solid, and the audio does not deviate from what one might expect in this class. Additionally, the TV supports DTS audio formats, which are often missing in much more expensive TVs. It's worth noting that this rating is subjective and may vary depending on individual preferences.
