I have an issue with ASUS ROG Strix XG27WQ and 6800XT at boot up. If I shut down the PC and leave monitor power on, the monitor goes to standby. Now when I turn on the PC, XG27WQ does not turn on. The PC boots and I hear a beep sound from bios that monitor is not detected. I need to turn off power to monitor and power it on again for the Windows Welcome screen to appear. It is very annoying but I am not sure how I could solve it. I am not sure if this is driver related or not as this happen when turning on PC. Otherwise the monitor works great. I have it since 2 months now. My work around until now is to turn off the monitor when turning off PC. Next time before I boot the PC I turn the monitor on just a few seconds before pressing power button of PC. This way monitor always turn on when booting and detects signal from 6800XT. The monitor is connected through display port.
