Our Verdict
Sony X75K
Sony X77L/X77CL
The Sony X77L/X77CL is a bit worse than the Sony X75K. The X77L has worse contrast, lower peak brightness, and worse gradient handling. It also has a slower response time, especially in shadow details, resulting in more noticeable black smear in dark areas of the screen.
