LG OLED G4 vs XIAOMI A PRO 2026

LG G4 guarantees an incredibly vivid HDR effect, placing the television among the very best. The equipment of the highest model in the producer's 2024 portfolio with the second generation of micro-lens technology (MLA) has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product from the Korean manufacturer may lag behind LCD televisions with Mini LED backlighting is during the full-screen scenes featuring a lot of white. If we disregard the latter type of scene, the average result would be even higher. It is also worth mentioning scenes with very fine details, where each one shines at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 palette makes HDR materials more engaging than ever before.

If you are hoping for a cinema-grade HDR effect in the new Xiaomi A Pro 2026, you better cool your expectations quickly. This television is simply too dim to fully showcase the capabilities of contemporary films or series designed for the highest image quality. Our measurements showed brightness in the range of 200–300 nits, which is more akin to SDR content than ambitious HDR productions. In practice, this means that while most films may look fine, they certainly won't evoke that "wow" effect that other televisions are known for. Fortunately, not everything is lost – we must credit the PFS LED filter used here, which is a solution similar to the quantum dot technology found in QLEDs. Thanks to this, the coverage of the DCI-P3 colour palette reaches about 94%, resulting in vibrant, saturated colours in the vast majority of materials.

The best factory mode in terms of colour reproduction was "Filmmaker". This was the one we used during our tests. Let's check how its characteristics looked before the calibration process. Looking closely at the white balance first, we can notice a significant dominance of red and green. As a result, the image had a warm yellowish hue. Such characteristics are typically observed in "Cinema", "Filmmaker" or similarly named modes. The effect of this colour balance was clearly visible in both SDR and HDR content, which after switching from "Standard" mode appeared distinctly yellow. Now, let's move on to two graphs that are responsible for the brightness characteristics and consequently the contrast of the image. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, midtones and bright whites were reproduced very accurately; however, it noticeably lost the darkest details, which merged into a black blob. Conversely, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. The colours themselves also posed a problem, as can be seen on the "ColorChecker" graph, since they were noticeably under-saturated.

What we saw in Filmmaker mode took us by surprise – and unfortunately not in a good way. The mode advertised as Hollywood standard resembled more of a shop window display. The white balance was shifted towards blue, leading to significant colour mistakes and burnt-out scenes in SDR content. It was slightly better, though still not perfect, in HDR materials. There were also issues there – the colour saturation and the entire palette consistently drifted towards cooler tones, resulting in an image that had more of an artificial, cold tint instead of a cinematic character. In other words: even in Filmmaker mode, which should showcase this television, we got an effect far from expectations.

The manufacturer has implemented extensive support for the calibration process in its LG televisions for many years. We therefore used 2- and 20-point greyscale adjustments, as well as an advanced CMS (Colour Management System), and got to work. As you can see, thanks to the procedure carried out, each parameter has significantly improved. The use of tools allowed for the achievement of extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and suitable colour saturation. This brings us as close as possible to the reference image, which is what the film director saw on the preview monitor. It is worth noting that the LG G4 televisions alone allow for even deeper intervention in image quality thanks to the ability to calibrate with 3D LUTs. However, this is a solution recommended only for post-production or graphic studios.

Although Xiaomi is not a brand associated with top-tier televisions, it must be acknowledged that even in a budget model like the A Pro 2026, the manufacturer left plenty of calibration settings. After a few adjustments, the SDR image gained a completely new look. Colours stopped drifting towards blue tones, whites took on a more natural quality, and most errors dropped to a practically invisible level. As a result, SDR content looked very good, surprisingly so for this price range.

It was somewhat different with HDR materials. Here, it was immediately evident what we had already mentioned – clipping in bright scenes and issues with balance control. Calibration helped only partly, as the limitations of the panel itself played a role. However, it must be emphasized that for SDR, the television had transformed beyond recognition and in a decidedly positive direction.

The tested television did not perform particularly well with materials rich in tonal transitions, as a result of which we could observe a strong posterisation effect. However, there is a partial remedy for this issue. 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 a high effectiveness of smoothing on light colours, although it is low on darker ones. We recommend primarily using the first one, as the other two interfere with the director's intentions by removing film grain.

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

Upscaling and digital image processing in the Xiaomi A Pro 2026 are not among the strengths of this model. One might expect that since the television was not designed to achieve record brightness levels, the manufacturer would focus on a more robust processor and a set of features that would "enhance" lower-quality images. Unfortunately – and here we are also faced with significant disappointment. On the positive side, we can note reasonably good upscaling, which handles HD materials and boosts them up to 4K in an acceptable manner. However, this is where the list of advantages ends. The television does not offer any features that improve tonal transitions or smooth out digital imperfections, so in most cases, we get a raw image, exactly as we deliver from an external source. On a large screen, such a lack of support makes lower-quality materials simply look bland. An additional problem is the phenomenon of overscan. When watching older materials, it happens that part of the image gets cut off, which only amplifies the impression that Xiaomi still has a lot of ground to make up in this category.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when the LG G4 is connected 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 high motion dynamics. For those requiring high image fluidity, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". This 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 level affecting the degree of smoothness, allowing everyone to find their golden mean.

The LG OLED G4 panel features an average response time of 0.78 ms (as directly derived from our measurements), enabling an incredibly clear image, unattainable by LCD televisions, which can have response times of several milliseconds. This is perfectly illustrated by the images from the "UFO Test", which show no trailing blur behind the object. Moreover, the LG OLED G4 test revealed that the television offers the ability to precisely adjust the motion smoothing function, allowing users to select the ideal level of image interpolation. We particularly appreciated this during fast-paced actions in video games, where the LG G4 performed exceptionally well, minimising any blurring. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sporting or cinematic scenes.

The fluidity of motion in the Xiaomi A Pro 2026 is an interesting compromise that arises from the hybrid matrix used here. At its native 4K resolution, the maximum refresh rate is 60 Hz – sufficient for those who mainly watch films and series. It is precisely with them in mind that the manufacturer has added a motion smoother, allowing users to adjust the image to their own preferences – opting for greater fluidity or leaving more "cinematic" frames depending on the settings.

The LG G4 television supports all the features that make up the HDMI 2.1 standard. During testing, each of them activated without the slightest problem, which allows us to consider the television as designed for gaming. Their functionality will surely be appreciated by both console users and those connecting the LG G4 to a computer. It is also worth mentioning the correct implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels exceeding the maximum luminance of the LG G4 will correctly map tones, and the game's visuals will remain true to the original.

A nice touch is the existence of a special GameBar, which we can call up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, enabling VRR technology does not degrade contrast, which is very common in televisions that feature local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emission. As a matter of editorial obligation, we will only mention a slight grey flicker, which is somewhat normal after enabling VRR.

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

Exactly – since Xiaomi has included the "Game Boost 120 Hz" feature, one might expect that they would follow up with a solid gaming package. Unfortunately, reality quickly dampens this enthusiasm. Aside from this mode (which, it must be admitted, is a great addition in a budget design), we only have a rather odd player panel. It's hard to call it a full-fledged "game bar" – it’s more of a simple overlay on the TV Menu with limited capabilities. And that would be about it. There’s a lack of ALLM, so the TV won’t automatically switch to game mode. There’s no VRR, so you can forget about smooth frame sync. We also won’t find support for Dolby Vision in games or the HGiG format, which are becoming increasingly standard on consoles. In short: besides the Game Boost 120 Hz, which actually allows for a more enjoyable experience at 1080p or 1440p, the Xiaomi A Pro 2026 offers nothing that could particularly attract gamers.
