What reviewers say

Both launch-era reviews praise the contrast, colour and gaming support. They disagree on sound: TechRadar found it spacious but prone to bass distortion, while WIRED strongly preferred a soundbar. WIRED thought discounted 2019 models offered better value; TechRadar found the picture refinements worthwhile, while also noting reflections and limited brightness compared with LCD rivals.
