If you're looking for a more budget-friendly option, the Sony X85K is significantly less expensive and delivers great performance for gaming and sports content due to its high gaming score and motion processing capabilities. Its bright room performance is satisfactory, but it may not be the best choice for darker rooms or for watching movies with deep black levels as it lacks local dimming. On the other hand, the Sony X90K, while costing more, offers better overall picture quality, especially in dark rooms due to its superior contrast and local dimming feature, which enhances the viewing experience for movies. Its sound quality is also higher, with more speaker power, which can enhance the audio experience. Both options have the same great upscaling and motion processing abilities, making them good for a variety of content. However, the X90K's slightly better color performance may be noticeable in vibrant, colorful scenes. The X85K and X90K are both 120Hz LCD TVs and support various HDR formats, but neither supports HDR10+. Your decision should be based on whether you value better dark room performance and sound quality over the price you're willing to pay. If you want to save on costs and mainly watch sports or game, the X85K is a strong choice, but if you watch a lot of movies and want better performance in dark settings, the X90K may be worth the extra investment.

The Sony X90K (LCD) is good for movies & TV, while the Sony X85K (LCD) is only fair.
The Sony X90K offers better overall movie and cinematic TV viewing primarily because it has local dimming, which enhances contrast and black uniformity, vital for deeper blacks and high-quality images in dark scenes. While the Sony X85K also has good color accuracy and black uniformity, the lack of local dimming means it cannot match the X90K's performance in these crucial areas, though it still provides clear images with well-defined colors.

The Sony X85K performs very well with upscaling and has excellent color accuracy out of the box, making it ideal for watching news, talk shows, and other TV programs.

The Sony X90K (LCD) is very good for bright room, while the Sony X85K (LCD) is good.
The Sony X90K is superior in a bright room compared to the Sony X85K because it has a higher HDR brightness and a better local dimming feature, which enhances contrast and bright scene portrayal, crucial for visibility in well-lit environments. On the other hand, while the X85K has a good SDR brightness for everyday content and acceptable reflections handling, its lower HDR brightness and lack of local dimming mean it's not as well-suited to combating bright room conditions as the X90K.

"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."
