What reviewers say

TechRadar and HIFI.DE praise deep blacks, convincing colours, responsive gaming and the clear webOS interface. Both find HDR less bright than the CX. TechRadar notices dark-scene noise and occasional stutter, while HIFI.DE finds motion processing effective with few artefacts. Both regard the built-in sound as serviceable.
