Wake from sleep - monitor not waking properly

Cheetah Designs · 12 Nov 2010 at 22:12

Basically when I wake from S3 sleep in Windows 7 my monitor doesn't switch on/I can't see anything on the screen. I know its booted properly because I can login and Shutdown blind. This is an intermittent problem as sometimes it will work fine and sometimes it won't.

My motherboard is:

BIOSTAR TA780G M2+
Graphics card ATI Radeon HD 3200. ONBOARD GRAPHICS CARD
Monitor connected via DVI cable.

What could be the problem/solution?

Still trying to figure this one out.

If I wake the computer up I get no display but if I put the computer to sleep again and then wake it up again it is fine?

what make of monitor do you have ?
slightly different I'm on vista laptop w/ samsung 2270hd as an extended monitor hdmi
and after s3 sometimes monitor does not come back on from standby and need to power cycle monitor.
[monitor standby on samsung implementation is odd since when source is removed - s3
monitor periodically/5mins shows a screen - no cable connnected - cannot inhibit this afain ]

I had an issue similar to this with my monitor, at boot I'd sometimes not get anything on screen but could hear windows load and could login to it blind and even start games. Turned out it was the graphics card, not the monitor that was the problem.

For over a year I'd simply assumed it was the monitor though and power cycled the PC until it'd work!

Well I have the latest drivers...I'm going to try switching back to VGA and see if it helps.
