XIAOMI A PRO 2025 vs LG OLED G6 (G64LW, G66LS)

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 LG G6 is currently one of the brightest OLEDs on the market. Its peak brightness reaches nearly 2500 nits and, best of all, this translates directly to real movie scenes. The TV flawlessly extracts details in the bright areas of the image. And this is regardless of whether we are talking about very small points in the form of stars in the sky or slightly larger elements on the screen. Naturally, with full-screen, uniformly white scenes, the brightness of the G6 drops due to the panel protection system (ABL). However, in real, varied movie shots, this value still hovers around an impressive 2000 nits, which can be considered a remarkable result. The coverage of the color palette also deserves praise. The new 2nd generation Tandem OLED panel has brought about only a cosmetic change, but still an improvement. The coverage of the DCI-P3 color space reaches nearly 99.5%, while the ultra-wide BT.2020 is around 84%. These are very good results, although it's important to remember one thing: at extremely high brightness levels, the volume of colors will be lower than in QD-OLED panels from Samsung Display due to the use of white sub-pixels (WOLED). However, in everyday content and most films, capturing this difference will be very difficult.

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.

We tested the LG G6 in the best factory mode for colour fidelity, which is FILMMAKER MODE. In the case of our test unit, this mode was reasonably well tuned straight out of the box. In SDR content, the only issue we noticed was the white balance, which leaned towards warmer tones. This made the image occasionally appear slightly yellowish, but overall, it wasn't a significant problem. The G6 performed a bit worse in HDR content. There, the white balance showed too much blue component. This caused the image to veer towards cooler shades, resulting in quite noticeable errors. As can be seen on our ColorChecker chart, the colours shifted towards these cooler registers. Nevertheless, considering the factory settings, the television presented a perfectly decent level. However, we know that OLED screens – particularly those from LG – respond exceptionally well to professional calibration, so we immediately proceeded to do just that.

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.

After completing a professional calibration, we gained complete control over the panel, and we managed to align all parameters to nearly zero. We were able to tune the white balance perfectly, which removed the factory's cool and warm tints from the screen. The effects are visibly clear in the ColorChecker test – the average colour reproduction errors dropped below the critical value of 1-2. And what does this mean? PERFECT colours, without any distortion! However, as a reviewer’s duty, we must point out how the LG G6 arbitrarily manipulates brightness, which is due to the EOTF curve's behavior. When we look at the standard synthetic graph, it might seem that the line is quite straight. However, the situation changes when we turn on the measurement filter, which shows how the television interprets brightness in actual, moving film scenes (EOTF in MOVIES). Then, it is clear as day that some of the smallest fragments on the screen are slightly overly brightened by the algorithm. Of course, for the average viewer, such a deviation will practically go unnoticed, but in the test of such an expensive screen, it’s worth noting – especially since we are talking about a model that has huge aspirations for the title of the best television of the year.

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.

No matter what one might say about the G6's issues with near-black signal, it must be fairly acknowledged that it handles heavily compressed material and lower resolution content extremely well. All unwanted, ugly tonal transitions are effectively reduced here by the "Smooth Gradation" feature. At the "Low" setting, the algorithm works flawlessly – effectively masking the artifacts resulting from strong compression without destroying the sharpness and details in the frame. Higher levels of this feature do further smooth the image, but they start to blur the real texture elements of the objects, so we recommend keeping this slider at a low level. As for the actual upscaling to 4K, the processor does an excellent job – edge sharpness and detail reconstruction are at the highest level, and in this respect, the G6 is on par with the global leaders.

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.

The LG G6 is an OLED television, so in the category of motion fluidity, it traditionally deserves the highest marks. The TV supports very high refresh rates of up to 165 Hz in 4K resolution, but most importantly – there are absolutely no signs of blurring on the screen. The response time of the matrix is virtually instant, ensuring that dynamic images remain perfectly sharp.

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 LG G6 is a true beast for gamers and one of the best-equipped TVs on the market in this regard. The manufacturer didn't compromise and equipped this model with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This means that no matter which port you plug in your PlayStation 5, Xbox Series X, or powerful PC, you'll get the absolute maximum performance out of them.

The TV supports a full suite of gaming technologies: from VRR (Variable Refresh Rate), to AMD FreeSync Premium Pro, and Nvidia G-Sync Compatible. Let's add to that a remarkably low, almost imperceptible input lag and an excellently functioning game panel (Game Optimizer), which allows you to constantly monitor signal parameters. Gaming on this screen, with the perfect black of OLED and powerful refresh rates, is pure pleasure.
