    Display always blank after waking monitor


    Alright, this one has me stumped.

    On my desktop PC that I leave on all the time I have the "Turn off the display" set to 30 minutes and works as advertised. The computer itself is never put into a sleep or hibernation state. However upon waking up the display it turns back on the monitor but displays nothing but a black screen. Same on secondary monitor, it is on and outputting nothing more than a black screen. No mouse cursor, no nothing. This worked just fine under Windows 7 with the exact same video driver (tried both AMD Catalyst 12.10 and AMD Catalyst 12.11 Beta11).

    Looking around online I see some people having a black screen issue from a full hibernation state but like I said above I don't use hibernation at all. Granted, I can just manually turn off my monitor all the time but eventually I'd wear out that switch and the automatic "Turn off the display" has always been a great feature of Windows operating systems.

    Any ideas?

    Is the monitor on the right source? DVI/VGA, sometimes they will switch to a secondary source if another goes idle. This should only happen if you have more than one device connected to the monitor. Try disconnecting any other devices and see if that helps.

    Yes. Like I said, it does turn both currently connected outputs back on (DisplayPort and HDMI), but just outputs black. Only correction from this state is Reset button...
