LG OLED G4 vs XIAOMI A PRO 2026

The LG G4 excels in delivering an incredibly vivid HDR experience, positioning it as one of the best models in its class. Equipped with second-generation Micro Lens Array (MLA) technology, it achieves a remarkable peak brightness of 1474 nits in real-world scenes. While it may not match Mini LED-backlit LCD TVs in full-screen white scenes, the overall performance is outstanding. The fine details in HDR content shine brightly, a distinct advantage of OLED technology over non-OLED displays. With this impressive brightness and wide DCI-P3 colour gamut coverage, HDR content is brought to life with unmatched engagement and immersion.

If you are hoping for a cinematic HDR effect in the new Xiaomi A Pro 2026, you better quickly cool your expectations. This TV is simply too dark to fully convey the capabilities of contemporary movies or series prepared for the highest quality picture. Our measurements showed brightness in the range of 200-300 nits, which are values that suit SDR content more than ambitious HDR productions. In practice, this means that most movies look okay, but they definitely won’t give you the "wow" effect that other TVs deliver. Fortunately, not everything is lost – a plus here is the use of the PFS LED filter, which is a solution similar to the quantum dot known from QLEDs. Thanks to this, the coverage of the DCI-P3 color gamut reaches about 94%, resulting in vibrant, saturated colors in the vast majority of materials.

Before calibration, the "Filmmaker" mode on the TV had a noticeable red and green colour dominance, resulting in a warm-yellow hue across both SDR and HDR content. This warm tone, typical of modes like "Cinema" and "Filmmaker," led to a yellowish cast that was evident when switching from the "Standard" mode.

Looking at the brightness characteristics, the Gamma chart showed decent performance for mid-tones and bright whites, but it struggled with the darkest details, which tended to merge into a black blob. HDR content, as represented by the EOTF curve chart, displayed a drop in contrast due to excessive brightness, which overshadowed fine details and negatively affected the overall image quality. Additionally, the "ColourChecker" chart revealed that colours were under-saturated, contributing to a less accurate and vibrant visual experience.

This provided a good foundation to build on, but calibration was needed to bring out the full potential of the "Filmmaker" mode and address these issues.

What we saw in Filmmaker mode surprised us greatly – and unfortunately not in a good way. The mode advertised as Hollywood standard resembled more of a display in a store window. The white balance was shifted towards blue, leading to huge color errors and the effect of washed-out scenes in SDR content. It was a little better, though far from perfect, in HDR materials. There, problems were also visible – color saturation and the entire palette consistently shifted towards cooler tones, which made the image appear more artificial and cold rather than cinematic. In other words: even in Filmmaker mode, which should be the showcase of this television, we got a result far from expectations.

The manufacturer has been offering extensive support for the calibration process in its LG televisions for many years. Therefore, we used 2- and 20-point grayscale adjustments along with an advanced CMS (Colour Management System) to optimise the display. As shown, the calibration procedure greatly improved each parameter. The results included studio-quality colour reproduction, enhanced detail in dark areas, corrected brightness characteristics, and accurate colour saturation. This led to a near-perfect match with the reference image—the one the film director saw on the preview monitor. It’s also worth mentioning that LG G4 televisions are unique in offering even deeper image adjustments through 3D LUT matrices, a feature primarily suited for post-production or graphics studios.

Even though Xiaomi is not a brand associated with top-of-the-line televisions, it must be acknowledged that even in a budget model like the A Pro 2026, the manufacturer left quite a few calibration settings. After a few adjustments, the SDR picture gained a completely new character. The colors stopped veering into blue tones, the whites became more natural, 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 material. Here, it was immediately noticeable what we had already mentioned - the overexposure of bright scenes and issues with balance control. Calibration only helped partially because the limitations of the panel itself played a role. However, it should be emphasized that in the case of SDR, the television transformed beyond recognition, and in a decidedly positive direction.

The LG G4 does not perform well with materials rich in tonal transitions, leading to a pronounced posterization effect. However, the manufacturer has included a smoothing system called "Gentle Gradation," with three levels: Low, Medium, and High. These settings are effective at smoothing bright colours, though less so for darker tones. It is recommended to use the Low setting, as the higher levels can distort the director's intentions by removing film grain.

When it comes to upscaling lower-quality material, the television's performance is quite good, delivering a sharp and clear image. However, attention should be paid to the jagged edges of fine details and the occasional halo effect around figures. This occurs due to the sharpening imposed by the LG G4, even when the lowest setting is selected (0). This is a noticeable change from the LG G3, which did not apply such strong sharpening, even at setting 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 TV wasn’t 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 quite disappointed here. On the plus side, there is reasonably decent upscaling that handles HD materials and elevates them to 4K in an acceptable manner. However, this is where the list of advantages ends. The TV does not offer any features to 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, this lack of support makes lower quality materials look simply bland. An additional problem is the phenomenon of overscan. When watching older materials, it sometimes happens that part of the image is cut off, which only intensifies the impression that Xiaomi still has a lot to catch up on in this category.

The LG G4 offers a maximum refresh rate of 144 Hz, achievable when connected to a powerful PC. For most users, however, the TV operates at a maximum of 120 Hz, ideal for watching sports or other content with fast motion. To improve image fluidity, the television includes the "TrueMotion" motion smoothing system, which features two separate sliders: De-Blur (for the sharpness of moving images) and De-Judder (for judder reduction). These sliders allow users to adjust the level of smoothing between 0 and 10, ensuring everyone can find the ideal setting.

With a response time of 0.78 ms, the LG G4 delivers exceptionally clear images, outperforming LCD televisions, which can have much slower response times. This results in no trailing blur behind moving objects, as shown in the "UFO Test." The TV also provides precise control over motion smoothing, which is especially beneficial during fast-paced video game sequences. Thanks to OLED technology, the G4 eliminates ghosting, ensuring a crisp and clear image even during the most dynamic sports or action scenes.

The motion fluidity in the Xiaomi A Pro 2026 is an interesting compromise that results from the hybrid matrix used here. At the native resolution of 4K, the maximum refresh rate is 60 Hz – sufficient for those who mainly watch movies and series. It is precisely for them 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 the more "cinematic" frames depending on the settings.

The LG G4 TV supports all the features encompassed by the HDMI 2.1 standard, making it a gaming powerhouse. During testing, every feature activated seamlessly, ensuring a smooth experience for both console gamers and PC users. Notably, the HGIG mode (HDR Gaming Interest Group) is implemented correctly, allowing games mastered to brightness levels higher than the TV’s maximum luminance to map tones accurately, preserving the game’s original visual integrity.

A notable highlight is the dedicated GameBar, which can be accessed at any time to quickly check or adjust game settings. More importantly, enabling VRR (Variable Refresh Rate) does not compromise contrast—a common issue in TVs with local dimming or Mini LED backlighting. This is thanks to the OLED panel’s self-emissive pixels, which maintain consistent contrast. However, a slight grey flicker may appear when VRR is enabled, though this is standard across OLEDs.

In summary, the LG G4, like most OLED TVs, is ideal for gaming and online competitions. Its HDMI 2.1 ports offer a full 48 Gbps bandwidth, supporting features such as VRR, ALLM (Auto Low Latency Mode), G-Sync, FreeSync, and HDR Dolby Vision gameplay, ensuring an exceptional gaming experience.

Indeed – since Xiaomi has added the "Game Boost 120 Hz" feature here, one might expect that they would 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 have just a rather bizarre player panel. It's hard to call it a fully-fledged "game bar" – it's more of a simple overlay on the TV Menu with limited options. And that would be about it. There is no ALLM, so the TV won't automatically switch to game mode. There is no VRR, so you can forget about smooth frame synchronization. We also won't find support for Dolby Vision in games or the HGiG format, which are becoming increasingly standard on consoles. In short: apart from Game Boost 120 Hz, which does indeed make playing more enjoyable in 1080p or 1440p, the Xiaomi A Pro 2026 offers nothing particularly appealing to gamers.
