What reviewers say
Reviewers agree it has superb, sharp OLED image quality with deep blacks, smooth 240Hz gaming and a strong port selection including a KVM switch. The main caveat is the high price; Trusted Reviews noted its HDR support is more basic than some rivals with Dolby Vision, and Windows Central wanted more customisable picture profiles.
