What reviewers say
Both reviewers praise the deep blacks, responsive gaming and convincing picture for the price. Brightness is a compromise beside higher-end OLEDs, particularly in bright rooms, and the two full-speed HDMI inputs limit connections. What Hi-Fi? finds the built-in sound dull; RTINGS finds dialogue clear but bass limited. RTINGS also notes imperfect HDR colour accuracy.
