Observed issue: When waking from sleep the computer wakes fine (fans spin up, hard drive is active) but neither monitor is active. Power cycling and unplugging replugging the display port cable does not help either. It works fine with only one monitor but with 2 or more it fails. The only way is to do a hard reboot which throws me into bios after an overclocking error. I don't even think I am overclocking! I discard and reboot changes in the bios (having not changed anything) and it runs fine.

Been searching for a solution for months now with no joy.

Asus z170ar mono, 1080ti gpu, win10, i7660k ( I think), Asus pg278 monitors.

like I and most other techs will say, sleep & hibernation modes are a big problem for everyone.  just don't use them and shut your computer down when sleeping.

or go in to power options and set pc to just turn the monitor off and leave the computer on all night (or day depending if your night owl or not).


you will better off in the long run and have less issues.


sleep and hibernation have been a problem since windows 95 and they just don't work good at all.
