What reviewers say
AVForums and Stuff found the Q8DN's 4K HDR picture bright and colourful with strong contrast, and both liked the Tizen interface. AVForums found local dimming slow in some scenes and occasional 50 Hz judder; Stuff noted motion issues and weak built-in sound. They differed on value and audio for everyday TV.
