What reviewers say

Reviewers agree it is one of the best 27-inch 4K OLEDs, praising very sharp text with no colour fringing, high brightness, accurate colour and fast, responsive gaming. Tom's Hardware found the sRGB modes slightly undersaturated and gamma light out of the box; PC Monitors saw VRR flicker and found the anti-flicker setting too aggressive.
