What reviewers say

Both reviewers praise deep blacks, rich colours and an accessible smart interface. What Hi-Fi? considers the picture close to the more expensive C8 and likes the PLA model's substantial sound. RTINGS highlights responsive gaming and wide viewing angles, but notes film stutter and dimming in large bright scenes.
