Samsung Neo QLED QN85D / QNX1D vs XIAOMI A PRO 2025

The HDR performance of the Samsung QN85D is a mixed bag. While it excels in synthetic luminance tests, reaching up to 1000 nits, and delivers impressive results in scenes with full-screen brightness – like in The Meg or the opening of Life of Pi – the limitations become apparent when smaller bright elements are introduced. In these cases, the brightness level noticeably dips, weakening the HDR effect and reducing its impact. When brightness hovers around 200-300 nits, the immersive “wow factor” of HDR tends to diminish, and visuals lose some of their intended brilliance.

That said, the QN85D still manages to deliver decent colour quality, covering 95% of the DCI-P3 colour space, which, while respectable, doesn’t set it apart from its top competitors. Colours appear accurate and vibrant, but the HDR experience could be more compelling if the brightness was consistently well-balanced across various content types.

In the HDR category, the Xiaomi A Pro performs poorly overall. Under ideal conditions, it achieves a brightness level of around 250 nits, which is underwhelming. However, many competing models offer similar or even lower brightness levels. Such limited brightness is insufficient to fully showcase the potential of HDR content. In practical terms, the image lacks the depth and intensity expected from high-quality HDR. Instead, the visuals resemble standard dynamic range (SDR), with scenes that should display striking brightness and contrast appearing flat and uninspiring. That said, for its price, the television offers solid DCI-P3 colour gamut coverage at 92%, made possible by its quantum dot (QLED) technology. This ensures vibrant and saturated colours, making it an appealing choice for gamers and movie enthusiasts seeking richer hues and improved colour reproduction compared to standard models.

The Samsung QN85D, when tested in Filmmaker Mode, falls short of expectations for film accuracy due to several notable issues in colour and brightness reproduction. In HD content, the white balance is skewed by an excess of red and blue, causing a pinkish tint across the image. This effect, confirmed by Colour Checker tests, impacts the realism of skin tones and other details, becoming particularly distracting in complex scenes.

For 4K HDR content, while the white balance intially appears accurate, there is a pronounced shift towards blue tones at the upper end of the spectrum. This deviation results in colours that lack natural appeal, subtly detracting from the viewing experience. The gamma, although close to the standard reference, slightly dips below the ideal 2.4 level, reducing shadow depth. Moreover, the EOTF curve for 4K content is noticeably elevated above the reference line, leading to excessive brightness in certain image areas. This undermines the cinematic look Filmmaker Mode aims to deliver, creating a visual experience that feels over-bright rather than authentically nuanced.

In summary, while Filmmaker Mode on the QN85D initially presents a cinematic effect, the inaccuracies in colour balance and brightness are too significant to achieve the true-to-source quality that the mode promises.

The Xiaomi A Pro 2025 performs best in movie mode for colour reproduction straight out of the box, though it is not without its flaws. An analysis of the white balance shows negative green values, causing distortions in white tones. At full white, there are noticeable deviations, and the high-contrast image leads to poor tonal transitions in red, negatively impacting the overall colour quality. Before calibration, the image often displays a pink hue in its scenery.

The gamma contrast graph falls below the 2.4 mark, indicating an overemphasis on darker tones and a lack of prominence in lighter areas. Additionally, the EOTF curve shows a sharp rise early on, which can result in lost detail in bright scenes and an oversaturated appearance. These issues suggest that further calibration is needed to balance the colour reproduction and enhance the overall image.

Factory colour settings on the Xiaomi A Pro 2025 are average, and while this is common in televisions of its class, users seeking accurate colour representation may need to adjust the settings. After proper calibration, the TV delivers a more natural and vibrant palette, aligning better with cinematic standards. For those prioritising precise colour reproduction, professional calibration will significantly improve image quality.

After professional calibration of the Samsung QN85D’s Filmmaker Mode, there's a noticeable enhancement in HD/SDR content quality. The calibration eliminates major issues with white balance, and adjustments to the brightness characteristics result in a more natural and lifelike picture. Regular HD content, like television broadcasts and YouTube videos, now benefits from well-balanced colours, free from the distracting hues that previously impacted image quality.

However, challenges remain with 4K HDR content. Despite calibration, improvements in white balance for HDR are minor, and more cosmetic than transformative. The EOTF curve initially aligns with reference standards in test conditions, but the television struggles to maintain consistent brightness during film scenes. As a result, dark elements appear overly boosted in mixed scenes, creating excessive contrast. In fully dark scenes, the image often becomes too dim, obscuring finer details and diminishing the overall viewing experience. This inconsistency in brightness affects the depth and accuracy of HDR performance, especially in more challenging scenes.

After calibration, the Xiaomi A Pro 2025 TV shows significant improvement. The white balance is the most noticeable change, with previous errors corrected in HD and 4K content. Most deviations are now minimal, falling within an acceptable range, resulting in a more balanced and natural colour representation that enhances viewing comfort.

In terms of gamma, the drop has been largely addressed, leading to a more consistent rendering of tones across various scenes. However, the EOTF curve still hasn't seen substantial improvement, as there is limited control over dynamic tone mapping. This limitation means that some details may still be lost in bright scenes, affecting the perception of certain materials.

Despite these minor issues, the overall picture quality is improved after calibration. The enhanced white balance and reduced gamma issues provide a more realistic and enjoyable viewing experience. While further adjustments could enhance the image even more, the TV now showcases its potential, meeting the expectations of many users.

When assessing the fluidity of tonal transitions in low-resolution materials on the Samsung QN85D, it's important to consider the noise reduction feature, which significantly improves problematic tonal transitions. However, this feature also has its drawbacks – it removes film grain, a crucial element in many productions that adds authenticity, and it can also soften the image. While this may appeal to those who prefer a smoother image, film enthusiasts who favour the authentic look of films may want to use this feature sparingly.

In terms of image scaling, the television performs very well. The model's figure is presented correctly, without noticeable distortions, and the branches in the background do not suffer from excessive artificial sharpness, a common issue when scaling lower-resolution content. The high capabilities of the image processor are evident, as it effectively handles lower-quality materials, ensuring a high-quality final image.

The Xiaomi A Pro 2025 handles tonal transitions effectively, especially when dealing with lower-quality materials. Thanks to its advanced digital processing, the colour contour removal feature performs surprisingly well. Setting this option to "Medium" provides the best balance, enhancing the smoothness of tonal transitions while avoiding excessive smoothing of other image elements, like film grain.

In the case of a tested frame featuring a model with numerous branches in the background, the TV demonstrated its digital processing strengths. Adding artificial sharpness clarified the model’s details, particularly enhancing the hair's definition. However, around the branches, subtle contours emerged due to digital intervention. While this adds detail to the overall image, excessive sharpness can sometimes cause certain elements to appear unnaturally highlighted.

The Samsung QN85D’s display boasts a 120 Hz refresh rate, which should satisfy both gamers and sports enthusiasts, providing a smooth and dynamic viewing experience. There are options for further improving fluidity, including a blur and judder reduction feature that allows precise adjustment of motion smoothness on a 10-point scale. Blur reduction enhances the sharpness of fast-moving objects, making action scenes clearer, while judder reduction smooths motion to eliminate the "stuttering" effect. Ghosting is generally well-controlled, although minor drawbacks may be noticeable in more demanding scenes, particularly when an object moves against a dark background. Additionally, the television features a BFI (Black Frame Insertion) option at a 60 Hz frequency, which can significantly enhance motion smoothness, although it comes with the potential downside of flicker, which may be bothersome for some viewers.

The Xiaomi A Pro 2025 features a motion smoothing option known as "Motion Smoothing," which is designed mainly for film viewing. It allows users to adjust the effect to either a more cinematic, film-like appearance with visible frames or a smoother, theatrical image. This feature will likely satisfy movie lovers. However, gamers and sports enthusiasts might be disappointed. The TV uses a 60 Hz refresh rate panel, typical for this price range, which doesn’t offer exceptional motion handling. Our "Ufo" test revealed some motion blur, so those seeking sharper moving images may find it lacking in this regard.

The Samsung QN85D is an excellent choice for gamers, offering a wide range of features that elevate gameplay quality and make it even more immersive. With a 120 Hz refresh rate, the image remains incredibly smooth, crucial during fast-paced action scenes in games. The TV also boasts low input lag, making player responses to commands almost instantaneous, enhancing control over characters and events on screen. Additionally, the Samsung QN85D supports VRR (variable refresh rate) and ALLM (auto low latency mode) technologies, optimising image fluidity and reducing lag by automatically adjusting the TV to meet gamers' needs.

The Xbox app, which enables cloud gaming without requiring a console, is another significant advantage, offering a seamless gaming experience without the need for additional hardware – a feature that sets Samsung TVs apart. The Auto Motion Plus Game feature is another notable addition. This motion smoother simulates a higher frame rate, making 30 fps games appear smoother, akin to 45 fps, while games at 60 Hz are upgraded to a 90 Hz experience. Most importantly, this feature does not introduce significant lag, ensuring the comfort of gameplay remains intact. It allows gamers to enjoy a smoother image without compromising responsiveness.

The Xiaomi A Pro 2025 includes several gamer-friendly features, such as the Game Bar, which sets itself apart from the typical dashboards seen in other brands. This feature allows quick access to game-related settings, making it convenient during intense gaming sessions. The TV also supports Automatic Low Latency Mode (ALLM), automatically switching to a game-optimised mode to reduce signal delays. However, it lacks HDMI 2.1 support, limiting compatibility with the latest gaming consoles that require higher bandwidth. Additionally, it does not support features like VRR (Variable Refresh Rate) or G-Sync, which are becoming essential for gamers seeking smoother visuals and reduced tearing. While the Xiaomi A Pro 2025 has some useful features, there are better options in this price range offering more advanced gaming solutions.
