What reviewers say

Reviewers praise its smooth 240Hz motion, bright and colourful picture, and useful connectivity. They find its low contrast and limited HDR performance less convincing. PCWorld also criticises the large stand base, while DisplayNinja recommends avoiding the fastest overdrive setting because of overshoot.
