Owner experiences and issues

  • Most owners praise the picture quality, deep blacks, vivid colours and the combination of 21:9 with 240 Hz; one uses it with an Xbox Series X and wished for a remote, another wished for a glossy rather than matte finish. On the negative side, one user found VRR flicker noticeable at 240 Hz and said the flicker-reduction feature does not work at that rate. Another said HDR did not work properly on their unit and was unhappy with ASUS support, and one reported the screen turned off after two weeks and never came back on. One review title complains about HDMI 2.1 support, but the text gives no detail.
