What reviewers say

Both reviewers praise deep blacks, natural colours and strong upscaling. What Hi-Fi? finds a sharper, punchier picture than the previous generation but criticises motion processing, confusing settings and thin sound. RTINGS highlights viewing angles and responsive gaming, while noting film stutter and dimming of large bright scenes.
