Our Verdict
Sony X900H
Sony X90K/X90CK
The Sony X90K/X90CK is a newer version of the Sony X900H, and the TVs are similar overall. The X90K gets much brighter, so it's better to use in a well-lit room, and it makes highlights pop more in HDR, so it's the better choice if you care about brightness. However, if dark room performance is important to you, the X900H looks better because it displays deeper blacks with better uniformity.
