Sometimes when I game with my x27 (in 98hz mode) with an HDR game, the monitor will randomly power down. I mean all the way down; no power light at all. In order to get it back to powering on, I have to actually unplug the power brick from the power supply and plug it back in. It is really annoying. I am obviously out of warranty (and I will never buy a refurb product from Acer again). Has anyone encountered this issue and is there a fix?
