LG OLED G4 vs XIAOMI A PRO 2026

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.

If you're counting on the cinematic HDR experience in the new Xiaomi A Pro 2026, it's best to temper your expectations. This TV is simply too dim to fully realise the potential of contemporary films or series designed for the highest quality image. Our measurements showed brightness levels in the range of 200–300 nits, which are values that are more suited to SDR content than to ambitious HDR productions. In practice, this means that while most films look decent, they certainly won't evoke the 'wow' effect that other TVs do. Fortunately, not everything is lost – credit has to be given to the PFS LED filter used here, 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 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.

What we saw in Filmmaker mode really surprised us – and unfortunately not in a good way. The mode advertised as the Hollywood standard resembled more of a display in a shop window. The white balance was shifted towards blue, which led to massive colour errors and the effect of blown-out scenes in SDR content. It was a bit better, though far from perfect, in HDR materials. There were also problems there – colour saturation and the entire palette consistently drifted towards cooler tones, resulting in an image that had an artificial, cold tint rather than a cinematic character. In other words: even in Filmmaker mode, which should be the showcase of this television, we got an effect far from expectations.

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.

Even though Xiaomi isn't a brand associated with top-tier televisions, it's fair to say that even in a budget model like the A Pro 2026, the manufacturer left plenty of calibration settings. After a few adjustments, the SDR picture took on a completely new look. The colours stopped veering into blue tones, the whites gained a sense of naturalness, 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 a slightly different story with HDR materials. Here, it was immediately noticeable what we had already mentioned – the overexposure of bright scenes and issues with balance control. Calibration helped only partially, as the limitations of the panel itself were at play. However, it must be emphasized that in the case of SDR, the television changed beyond recognition, and definitely for the better.

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.

Upscaling and digital image processing in the Xiaomi A Pro 2026 are not among the model's strong points. One might expect that since the television was not designed to achieve record brightness levels, the manufacturer would have opted for a more robust processor and a set of features that would "enhance" lower quality images. Unfortunately – we were also met with significant disappointment here. On the plus side, it has reasonably decent upscaling, which handles HD content and boosts it to 4K in an acceptable manner. However, that is where the list of advantages ends. The television does not offer any features to improve tonal transitions or smooth out digital imperfections, so in most cases, we receive a raw image, exactly as we deliver it from an external source. On a large screen, this lack of support makes lower quality content look simply bland. An additional problem is the phenomenon of overscan. When watching older material, it happens that part of the image is cut off, which only intensifies the impression that Xiaomi has quite a bit of catching up to do in this category.

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.

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

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.

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