Samsung Neo QLED QN90D / QN92D vs Sony X85L

During synthetic tests, the Samsung QN92D demonstrated remarkable brightness capabilities, reaching an impressive 2000 nits—on par with top models in the market. This level of brightness puts it at the forefront for displaying HDR content, where high brightness is essential. But how does it fare in real movie scenes? Under favourable conditions, such as the light-drenched opening and closing scenes of Life of Pi, the QN92D nearly replicates its lab results, delivering striking brightness levels. However, performance changes in scenes featuring small, bright objects against dark backgrounds, such as the fourth scene in Sicario. Here, brightness levels drop significantly, with maximum values capping at around 600 nits.

As with contrast, these limitations are due to the aggressive local dimming algorithm, which aims to reduce the "halo" effect around bright objects in dark scenes but often sacrifices overall brightness. Consequently, while the TV excels in scenes with abundant light, it faces challenges maintaining brightness with smaller, bright elements on dark backgrounds.

The Sony X85L TV offers solid HDR performance with a brightness level of 750 nits, which is sufficient to enjoy vivid effects. In scenes of moderate difficulty, such as the first, third, or fifth test scenes, a brightness of around 600 nits allows one to fully experience the HDR effect. Unfortunately, in more demanding segments, such as the scene from the movie Sicario 2, the TV shows its limitations. Drops in brightness to 250 nits make the HDR effect lose its impressive quality and resemble regular SDR instead. Nevertheless, it is worth highlighting the very good coverage of the DCI-P3 color palette at 95%, which definitely deserves praise and positively affects the overall image quality.

The best mode for colour reproduction on the Samsung QN92D is Filmmaker mode. Although it generally offers good colour quality, it is not without significant issues. Starting with HD/SDR image quality, the main challenge is white balance. The graphs reveal considerable instability, with a dominant red tint that makes the image appear too warm. This imbalance causes shades to shift unnaturally towards warmer tones, potentially affecting the perception of natural colours. Additionally, while contrast, as indicated by the gamma chart, is not the worst, it still falls short of the ideal, impacting overall image quality, especially in darker scenes.

This issue continues with 4K content, such as high-quality series or films. Here too, white balance proves problematic, with noticeable deficiencies in both blue and red, leading to tonal shifts. Tests using the Colour Checker tool confirm these issues, showing a tendency for colours to skew toward yellow hues, further distorting the natural look of the image. While Filmmaker mode remains one of the best options for cinematic content, it could still benefit from improvements, particularly in colour accuracy and white balance.

The Sony X85L television was tested in IMAX Enhanced mode, which, although associated with world-class cinema, does not guarantee an image that aligns with the director's vision. The main issue is the white balance – there is a noticeable strong dominance of blue color and significant lack of red. As a result, the image becomes unnaturally cool and appears artificial. The color reproduction errors were confirmed by the Colour Checker test, which showed significant discrepancies – colors were "scattered" like shots from a rifle, and only a few samples hit the target values. This clearly shows that the precision of color reproduction leaves much to be desired.

The brightness of the image is one of the positive features of the TV. The gamma for HD content is at an acceptable level, although there are minor errors, but generally, it is quite good. However, the brightness characteristics for 4K materials remain an issue, controlled by the EOTF curve. It is evident that very small, bright elements of the image are too dim, which is a result of the limited number of dimming zones due to the design of the television.

After calibration, the Filmmaker mode on the Samsung QN92D shows significant improvement, particularly with SDR content. The white balance has been greatly enhanced — previous colour shifts and red dominance have been corrected, resulting in more natural colour reproduction. Although the gamma curve didn’t require major adjustments, its stabilisation has positively impacted overall picture quality.

In high-quality materials, the white balance has also improved. However, contrast remains an area to watch. The EOTF curve initially appears accurate, but closer inspection reveals that the television struggles to maintain consistent contrast in film content, indicating further room for improvement. Despite these areas, one advantage is the TV’s colour saturation. Skin tones are rendered well, and while some colours may be slightly oversaturated, the overall effect is rich and vibrant.

Despite minor contrast limitations, the calibrated Filmmaker mode on the Samsung QN92D delivers excellent picture quality, with natural colours, making it a strong choice for movie watching.

Thanks to the use of calibration tools offered by Sony X85L, the image quality has been significantly improved. After calibration, the white balance for HD content is much more stable, making colors look more natural and the image gains authenticity. Although it is not perfect, these changes allow viewers to enjoy a more realistic representation of colors, eliminating the earlier cool tone. The gamma, which already performed decently, has been adjusted to an even better version. As a result, tonal transitions and brightness are more consistent, positively affecting the depth and detail of the image.

As for 4K content, despite efforts, the white balance still struggles with a deficiency of red, which can result in overly warm colors in some scenes. Synthetic tests showed that the EOTF curve in HDR is quite stable, with a slight boost in mid-bright scenes. However, in real film materials, the TV can still be too bright with fine, light details, which is a result of the limitations of large local dimming technology.

Nonetheless, calibration has brought significant benefits, particularly in color accuracy, improving overall image quality and providing a more natural and cohesive directorial vision.

Let's examine how the Samsung QN92D television manages tonal transitions in low-quality materials. The noise reduction function is highly effective, enhancing the fluidity of tonal transitions even under challenging conditions. However, it’s worth noting that, as with other Samsung televisions, this feature can occasionally remove desirable elements, such as film grain, which may affect image authenticity. 

In terms of digital processing, the Samsung QN92D also performs impressively. During testing, the image appeared natural and well-balanced, with details like background branches precisely reproduced, underscoring the television’s ability to enhance the quality of low-resolution materials.

In terms of smoothing tonal transitions, the Sony X85L television does not offer any dedicated enhancement options, which is a downside. On the other hand, image scaling performs quite well – the television adds a bit of artificial sharpness, which can make details such as tree branches more pronounced, although sometimes with noticeable jaggedness. This type of effect may appeal to some viewers who prefer a more detailed image.

The Samsung QN92D TV features a 144 Hz panel, however, when using the motion smoother, the maximum refresh rate adjusts to 120 Hz. This setup ensures excellent picture quality for both gamers and sports enthusiasts. Additionally, the TV offers a range of image enhancement options, such as the "blur and judder reduction" feature, which lets users fine-tune smoothness on a 10-point scale. Blur reduction sharpens fast-moving objects, while judder reduction smooths out motion, eliminating the "stutter" effect. With these advanced settings, the Samsung QN92D provides optimal visual experiences for dynamic scenes and intense gameplay alike.

The TV performs impressively in terms of motion blur, with minimal issues. The only minor drawback is a slight overshoot effect noticeable on dark backgrounds in our "Ufoludkiem" test. Nonetheless, with its advanced smoothness settings, the Samsung QN92D delivers outstanding performance for both fast-paced scenes and immersive gaming sessions.

The Sony X85L, equipped with a 120 Hz panel, will meet the expectations of a wide range of users – from sports and gaming fans to movie buffs.

This model provides virtually every gaming feature currently available, enhancing the excitement of gameplay. A standout feature is the 120 Hz panel, delivering impressive motion smoothness, which is especially beneficial during action-packed games. The TV also boasts low input lag, ensuring quick responses to player commands. Additionally, VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) optimise refresh rates and automatically activate gaming mode, further elevating the gaming experience. An additional bonus is the Xbox app, enabling users to play directly on the TV without needing a console—an exclusive feature in Samsung TVs, adding to their appeal in the gaming world.

Samsung’s Auto Motion Plus Game feature deserves particular praise. This motion smoother is highly effective in gaming, making lower frame rates appear smoother—30 frames per second can look like 45, and 60 Hz can resemble 90 Hz. Crucially, it achieves this without introducing noticeable input lag (keeping it below 25 ms), so gameplay remains highly responsive, unlike many other motion-smoothing options on the market. As a result, players can enjoy a smoother visual experience without sacrificing responsiveness.

Sony X85L offers quite a solid set of features for gamers, making it an attractive choice for gaming enthusiasts. First and foremost, the TV has a 120 Hz panel, translating to smooth and dynamic image display, ideal for both fast-paced action games and more demanding sports titles.
