Hi all, I need wake up PC from sleep to perform some actions - from C#. I've used CreateWaitableTimer functions, everything goes fine, at given time PC wakes up - but monitor stays in power save mode (turned off). So i want to know - how possible to turn on monitor after wake up?

PS I've tried "Complete Guide on How To Turn A Monitor On/Off/Standby" - with SendMessage (Codeproject) and SetThreadExecutionState(ES_DISPLAY_REQUIRED) - it doesn't work

Any ideas?
