The Samsung QN90B offers excellent overall picture quality and brightness, making it a strong choice for a sunny room. It also has great gaming performance with a high refresh rate. However, it comes at a premium price compared to the Sony X85K. The Sony X85K is more economical, still delivers good picture quality, and performs exceptionally well with upscaling content. Yet, it lacks local dimming, which impacts its performance in darker scenes and might not be as bright as the Samsung, making it less ideal for very bright rooms. If budget isn't an issue and you want top-notch brightness and gaming features, go for the Samsung QN90B. If you're looking to save money and still get good quality, especially for upscaling and overall usage, consider the Sony X85K. Give Feedback

The Samsung QN90B (LCD) is very good for movies & TV, while the Sony X85K (LCD) is only fair.
The Samsung QN90B is considered very good for watching movies and cinematic content because it has excellent qualities like a high contrast with local dimming and strong black uniformity, which contribute to deep blacks and a good HDR experience. Meanwhile, the Sony X85K, while offering high contrast, lacks local dimming and has lower black uniformity, so the depth of blacks and shadow detail are not as pronounced, making it only fair for movies and cinematic TV.

The Samsung QN90B (LCD) is excellent for news, talk, & other TV, while the Sony X85K (LCD) is very good.
The Samsung QN90B stands out for its excellent SDR brightness, making it particularly suitable for viewing in well-lit environments such as when watching news and talk shows during the day. Although the Sony X85K also offers very good SDR brightness and better upscaling, which is crucial for watching lower resolution content, its performance is slightly overshadowed by the Samsung's superior colors out of the box and local dimming feature, which enhances contrast and provides deeper blacks.

The Samsung QN90B (LCD) is best in class for bright room, while the Sony X85K (LCD) is good.
The Samsung QN90B is better suited for viewing in a bright room primarily due to its higher SDR and HDR brightness as well as superior handling of reflections. Conversely, the Sony X85K, while offering good performance, falls short in these aspects, particularly in HDR brightness and reflections, which affects its capability to deliver optimal picture quality in well-lit environments.

The Sony X85K (LCD) and Samsung QN90B (LCD) are both good for sports.
The Samsung QN90B is well-suited for sports due to its excellent motion processing capabilities, which minimize blur during fast-paced scenes, and its very good reflection handling which keeps the picture clear even in bright environments; however, its viewing angles are only decent, meaning the picture may not be as consistent from side seats. In contrast, the Sony X85K boasts perfect motion processing and good reflection handling, providing a smooth and sharp viewing experience, but it has poorer gray uniformity, which could slightly affect the appearance of sports fields or courts under certain conditions.

The Samsung QN90B (LCD) and Sony X85K (LCD) are both very good for cartoons & animation.
The Samsung QN90B excels in reproducing vibrant and accurate colors straight out of the box, which is essential for animated content that often uses a wide array of colors. Both the QN90B and Sony X85K display a wide color gamut; however, the Samsung has superior SDR brightness and contrast, resulting in a more vivid and dynamic picture for cartoons and animations.
