What reviewers say

Reviewers praise its fast IPS response, low input lag and useful adaptive sync, alongside vivid colour and an sRGB mode. Both criticise its weak contrast and limited HDR effect, and find the advertised 1ms setting produces excessive overshoot. TFTCentral also found the stand adjustments stiff.
