If you are looking for a more budget-friendly option, the Sony X85K is often significantly less expensive and offers good overall picture quality, excelling in gaming and sports content. On the other hand, the Sony X90J, while typically more expensive, provides a higher overall picture quality, particularly shining in dark room settings. It also has good bright room performance, making it a versatile option if you are willing to invest more. Both models may not be ideal if used in very bright rooms as their performance under such conditions is not the best. Consider how you prioritize gaming, dark room viewing, and budget when making your decision. Give Feedback

The Sony X90J (LCD) is good for movies & TV, while the Sony X85K (LCD) is only fair.
The Sony X85K offers lower contrast and does not feature local dimming, affecting its black uniformity, which is less than ideal for movies and cinematic TV where dark scenes and deep blacks are prevalent. In comparison, the Sony X90J benefits from better contrast, effective local dimming, and superior black uniformity, resulting in a more immersive experience for the same content.

The Sony X90J (LCD) is very good for gaming, while the Sony X85K (LCD) is good.
The Sony X90J is preferred for gaming over the Sony X85K because it has a superior response time, meaning on-screen movement will be crisper, and less motion blur when playing fast-paced games. While both have low input lag for quick gameplay responsiveness, the Sony X90J's better response time gives it an edge, especially noticeable in high-speed gaming situations.

The Sony X90J (LCD) and Sony X85K (LCD) are both very good for news, talk, & other TV, though the Sony X90J (LCD) is somewhat better.
The Sony X85K excels in upscaling and SDR brightness, making it a solid choice for watching news and talk shows in various lighting conditions, though it doesn't have local dimming to enhance the contrast. On the other hand, the Sony X90J also performs well in upscaling and SDR brightness, and it benefits from better local dimming and contrast handling, which may provide a slight edge for darker room viewing, but it has poorer performance under bright lighting due to its screen reflections.

The Sony X85K (LCD) and Sony X90J (LCD) are both good for sports.
The Sony X85K handles reflections better and has a good response time which is well-suited for watching sports in bright rooms, while the Sony X90J, with slightly poorer reflection handling, has a very good response time offering a clear advantage in fast-moving scenes typical in sports. Both TVs have excellent motion processing, but viewers watching at wide angles might prefer the X85K for its slightly better viewing angles, although neither is ideal for off-center viewing.

The Sony X85K (LCD) and Sony X90J (LCD) are both very good for cartoons & animation.
The Sony X85K and Sony X90J both provide excellent colors right out of the box, which is crucial for animated content that often uses a wide and vibrant range of colors. While both TVs have a good color gamut, ensuring that they can display a wide range of colors, the Sony X90J has a slight edge in color volume, which means it can maintain the accuracy of those colors across a range of different brightness levels.

The Sony X90J (LCD) and Sony X85K (LCD) are both good for bright room.
Both the Sony X85K and Sony X90J have been noted as strong performers in bright rooms due to their very good SDR and HDR brightness, which means they can maintain visible picture quality even in well-lit environments. However, the Sony X85K has better management of reflections according to the listed specifications, while the Sony X90J falls short in this area, affecting its viewing quality in very bright or directly-lit rooms.
