XIAOMI A PRO 2025 vs LG OLED B6

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.

LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year's B5. That's down to LG Display's new budget OLED SE panel. In practice this simply provides a bit more headroom and makes HDR look fuller in many scenes than on last year's lower-end OLEDs. That doesn't mean the B6 has no limitations. In very bright shots, when a large part of the screen is brightly lit, brightness can fall below 400 nits. This behaviour is typical of OLED TVs (especially in this segment), and it's then you see the biggest difference compared with pricier models. All the same, we rate the B6's results as really solid. It's still not a TV built to break brightness records, but the HDR effect is strong enough that films really feel like a step up from ordinary SDR picture.

Colour gamut

Using the OLED SE panel has had some impact on wide colour-gamut coverage. Compared with last year's model the figures have dropped by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn't mean the colours on the LG B6 are weak. In most films and TV series they look vivid, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD-OLED panels. This is due to the WOLED panel structure. In addition to the red, green and blue subpixels it also uses a white subpixel that helps boost brightness. This comes at a cost: at very high luminance some of the colour is effectively 'diluted' by the white light, so saturation of some hues can be slightly lower. Day-to-day it's not a big problem, but you can see it in the most demanding scenes.

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 B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes give very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is a far better starting point than Vivid or Eco, where the picture is heavily boosted and noticeably less natural. For SDR content the factory settings perform really well. Colour errors are small, gamma behaves correctly, and the picture looks natural during regular viewing and does not seem overly enhanced.

It's a bit worse with HDR. Once you start playing that kind of content it's quickly apparent the white balance isn't perfectly set. Too much blue and red makes the image take on a slightly pink tint. Colour gamut measurements and the ColorChecker confirm this, with samples clearly shifting in that direction. It's not a defect that completely ruins the picture, but you can notice it with HDR films. So anyone who wants the most faithful image should consider calibration, which we cover later in the review.

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.

During calibration we focused mainly on HDR material, because that’s where the factory settings needed the most correction. We didn’t neglect SDR, though. After tuning it was brought almost to perfection. Colours are very accurate and brightness is controlled as it should be. The biggest change in HDR came from improving the white balance. After removing excess red and blue the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colours that had previously leaned towards pink improved. After calibration most errors fell below Delta E 2-3, the threshold at which an average viewer stops noticing differences with the naked eye. So the LG B6 can produce a very accurate picture, especially for the manufacturer’s entry-level OLED model.

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.

LG B6 copes very well with lower-quality material. Much of that is down to effective digital image processing, which can mask some source imperfections without excessively smoothing the whole scene. The "Smooth Gradation" feature proves particularly useful. It lets you noticeably reduce posterization mentioned earlier, especially in dark parts of the image. The safest choice is to set it to Low or Medium. The feature still effectively smooths out harsh tonal transitions, but doesn't yet interfere too much with fine details. Die-hard purists can of course leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a fair amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations are only noticeable with very poor sources below 720p, where the smallest text and fine elements aren't always perfectly sharp, but this is true for almost every other TV on the market.

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.

One of the biggest advantages of OLED panels is their very fast pixel response time. That keeps the picture sharp and prevents visible smearing that often appears on LCD TVs. It does have a downside, though. During slow camera pans motion can look a bit choppier than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 this is easy to tame with TruMotion. With the motion smoothing set correctly you can get smoother motion without giving the picture an exaggerated soap-opera effect.

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.

LG OLED B6 has plenty going for gamers; it's a complete base for the PS5, Xbox Series X/S or a solid PC. It comes with four full-size HDMI 2.1 ports with 48 Gb/s bandwidth, so you can forget about annoying cable swapping when you want to connect several newer devices at once. We get a full package of sync technologies, from classic VRR to G-Sync and FreeSync. The panel effortlessly syncs its refresh rate to the frame pacing produced by your console or graphics card. Of course ALLM is present: the B6 automatically recognises when a game is running and immediately cuts latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG means that after an initial calibration in the console settings the picture won't suffer from blown-out whites or lost detail in bright areas. The icing on the cake is the Game Bar. Instead of digging through the full menu mid-game, a single click lets you correct shadow visibility, tweak chosen parameters or simply check the display's current mode. All of this makes the LG B6 a great choice for gamers.
