Is it ok in Safe Mode ?
Press F8 right after the post screen and go to Safe Mode.
Go to Control Panel - Power Settings and change the power settings for monitor sleep mode.
Turn on monitor alone, go into the monitor Menu, via navigating monitor buttons and change timeout/sleep settings there.
It is not okay in safe mode and still goes black while on. I have literally tried everything I can think of. I have hooked my monitor up to my laptop and it still does this. I gave up and ordered a new monitor. I don't think it could be the sleep mode because nothing was changed there and I never had the problem before. Thanks for the advice!
