Sony Bravia 9 (XR90) vs Samsung QN900D Neo QLED 8K

The brightness performance of the Sony Bravia 9 is exceptional. Each scene reaches over 1500 nits, and the television can shine even brighter during movie playback. This level of brightness provides an extraordinary viewing experience, allowing for immersive interaction with high-quality video content. Thanks to its extensive coverage of the DCI-P3 colour gamut, the image is vibrant, and when combined with such high luminance, it almost feels alive. With its impressive peak brightness, viewers can fully appreciate the colour range, even in the most challenging scenes involving dynamic lighting changes. The Bravia 9 also supports Dolby Vision and HDR10 formats, further elevating the viewing experience.

Under synthetic testing conditions, the television showcased its impressive light output, achieving 1400 nits, which is undeniably remarkable. This capability was also evident in the opening scene of Life of Pi, featuring a vibrant sunrise. However, due to certain dimming algorithm issues, some drawbacks are noticeable. For instance, in test scenes from Sicario 2 and the second scene of Life of Pi, the brightness levels dropped to an average of 500-600 nits. While this performance isn't poor by Mini LED standards, expectations were higher given the premium price of the TV. Nonetheless, the set should be commended for covering a wide colour gamut of DCI-P3 at around 96%. Although some technologies offer higher coverage, this is still a commendable result.

The "IMAX Enhanced" factory mode has remained the best option in Sony televisions for years, and it was used throughout the entire testing process. While it aligns closely with the reference compared to other predefined settings, improvements could be made for a better viewing experience.

In SDR materials, the gamma shows a noticeable boost, which leads to over-contrasting the image. Additionally, the beginning of the graph deviates significantly from the reference, resulting in merged details in the darker areas, creating an unpleasant uniform blotch. The EOTF curve in HDR content, on the other hand, appears mostly correct, with only minor deviations from the reference.

However, the most prominent issues affect the white balance. There is a persistent green colour dominance, leading to problems with grey tones and overall colour misalignment. This imbalance in the white balance gives the image an unwanted greenish tinge, negatively impacting the overall visual quality.

The television includes a Filmmaker mode, intended to present films in the most authentic way possible, but it does come with some issues. For HD content, the white balance shows a dominance of red and blue, giving the image a pinkish hue. Conversely, for 4K HDR content, the levels of blue and red drop, resulting in a warming effect that shifts colours towards yellow tones. Colour Checker tests confirm this tendency, with colour samples visibly drifting in this direction.

In terms of brightness and contrast, the gamma is notably disrupted. The main issue is a marked spike at the start of the graph, indicating that dark details are excessively brightened, which reduces depth in the darkest parts of the image due to zone dimming. For 4K HDR content, the EOTF curve performs reasonably well but falls below the reference level, affecting the overall image dynamics.

The colour reproduction after the calibration process on the Sony Bravia 9 is nothing short of excellent. Regardless of the signal, whether SDR or HDR, the image comes remarkably close to the director's intended vision. Nearly every flaw in the image has been meticulously modelled and corrected to a high degree.

This impressive result can be attributed to the advanced tools available for calibration, which Sony has been offering in its televisions for years. Notable tools include the 2- and 20-point grayscale calibration and a very comprehensive CMS (Colour Management System). These features allow for precise adjustments, ensuring that the colours and overall image quality are as accurate and faithful to the source material as possible.

After calibration, the Filmmaker mode truly lives up to its name. The white balance for both HD and 4K HDR content has been significantly improved, resulting in more natural and consistent colours. The pink hues in HD content and the yellow tint in 4K HDR have been effectively eliminated, enhancing the realism of the image. As a result, the television now offers much better colour reproduction, positively impacting the overall viewing experience.

However, when it comes to brightness, the gamma curve now reveals a noticeable drop at the beginning, making the darkest details more difficult to discern. The EOTF curve for 4K HDR content remains largely unchanged and still falls short of the reference level, meaning the television continues to struggle with maintaining appropriate brightness. This issue is tied to the aggressive dimming algorithm, which affects overall brightness and black levels.

Despite the limitations associated with local dimming, the television has seen an improvement in colour reproduction quality. The Color Checker test results confirm that the colour samples are now much closer to the standards, resulting in a more natural and visually pleasing image.

When analysing the quality of tonal transitions and image scaling, especially for lower-quality materials, the improvement after activating the function for tonal transitions is clear. By default, the quality is quite average, but once the function is turned on, even at the lowest setting, the results are among the best we've seen. This feature can be enabled without worrying about negative side effects, such as film grain blur.

Sony's "XR" processor, which the brand has been touting for several years, lives up to its reputation for image scaling. The image quality is incredibly sharp while maintaining a very natural look. This reinforces that Sony's processing technology is one of the best available, particularly when handling lower-resolution content.

The smoothness of tonal transitions in lower-quality materials looks great – the Noise Reduction function effectively smooths tonal transitions while eliminating film grain. Although removing grain is not always desired, the final effect looks very aesthetic, especially for those who prefer a cleaner image.

As for upscaling, the Samsung QN900D demonstrates the enormous capabilities of the new AI technology processor. Photos and materials in lower resolution are upscaled while retaining many details – for example, a photo with a model looks great, devoid of unnecessary jagged edges, and the branches in the background are not overly aliased.

The maximum refresh rate of the Sony Bravia 9 is 120 Hz, the minimum for those primarily watching sports or other high-motion content. This refresh rate ensures the image remains sharp and smooth, even during fast-paced scenes. For more demanding users, Sony has implemented an advanced motion smoothing system, divided into three distinct segments: Smoothness (Film), Smoothness (Camera), and Clarity. These settings can be adjusted to various degrees, allowing users to fine-tune the picture to their preferences. For example, a setting with slight smoothing can be used to avoid the "soap opera effect," delivering a more natural and cinematic viewing experience. This level of customisation ensures that viewers can find their ideal balance between smoothness and clarity.

The Samsung QN900D is currently the fastest television in the world – quite literally. With an impressive refresh rate of 240 Hz at 4K resolution, it offers a remarkable performance that PC gamers will undoubtedly appreciate. Movie enthusiasts will also find much to admire, as Samsung provides a 10-level scale in the picture clarity settings, allowing for extensive image customisation. Users can choose whether they want the television to deliver a smoother, more fluid effect at the highest settings, or a more cinematic experience with visible frames at the lowest settings.

The Sony Bravia 9 television is equipped with four HDMI ports, but what is puzzling for a device of this class is that only two of them operate in the 2.1 standard. Despite this, it should not detract from the fact that nearly all features work excellently, providing a positive experience when using them. Games running in HDR10 or Dolby Vision benefit from low input lag, ensuring a comfortable gaming session. The solid implementation of the HGIG mode is a noteworthy feature, as, after proper calibration, it closely aligns with Dolby Vision.

Sony introduced the GameBar feature to its televisions last year, a standard for many manufacturers. This feature allows for quick adjustment of settings without exiting the game. Its implementation has been seamless, offering conveniences such as a crosshair grid, black level adjustment, and reducing the screen to gaming monitor proportions.

The Sony Bravia 9 will find its fans, particularly among PlayStation enthusiasts. It is a natural pairing since the console and the television share identical capabilities. However, more broadly speaking, despite the minor issues with Dolby Vision in games, the Bravia 9 remains a very good television for gaming overall.

The Samsung QN900D is excellent for console gaming, packed with features gamers will truly appreciate. It comes with 4 HDMI 2.1 ports, but they do not support the full 48 Gb/s bandwidth. However, for most users, this bandwidth is more than adequate. The TV also supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR), which ensures smoother gameplay and eliminates screen tearing during fast-paced action. Features like G-Sync and FreeSync are also supported, enhancing compatibility with both consoles and PCs equipped with compatible graphics cards, helping to reduce stuttering and provide a smooth image.

A standout feature exclusive to Samsung is the Xbox Game Pass app, allowing users to stream games directly to the TV without needing an Xbox console. This is a very convenient option for gamers who want to enjoy their favourite games without purchasing additional hardware. The Samsung QN900D also features a Game Bar, which provides quick access to gaming-related settings, making it easy to configure the TV for optimal performance.

The Auto Motion Plus Game function offers a special motion smoothing mode that increases the frame rate (up to 4K@60Hz). Importantly, this does not raise input lag significantly, so players can enjoy smoother visuals without sacrificing responsiveness. With all these features, the Samsung QN900D is a top-tier choice for gamers seeking a television with the best possible specifications.
