I run a dual monitor configuration (Asus VG248QE as primary on Displayport @ 144hz, Asus VE248H on DVI as secondary monitor @ 60hz). Using any 34x.xx driver, I get a black screen on my primary monitor when I try to come out of standby (monitors turn off by power options settings) and sleep. I think prior to my format, the 344.11 drivers were working fine. I dont know what could be causing this. I have all power settings features turned off (C-State, EIST, All PCI-Express settings), I also use High Performance as my power scheme. However, despite everything being turned off, it seems to happen. Technically the solution is to set "display turn off" and "sleep" to never, but it doesnt fix my problem. I need to restart my computer to fix this problem. This does not happen with stock Microsoft drivers, but for obvious reasons those are unusable. I resetted my display, but same issue. It happens when my card is at stock and overclocked. Help would be welcomed, thanks. EDIT: Hibernation works fine.
