Win7 only showing 1 monitor after waking up from sleep.

Recently after waking up from sleep, windows would only show my main monitor with my secondary blacked out. I had to go to screen resolution> extend display to get the 2nd monitor working. I have a BenQ fp241vw for main and the HP2335 for secondary, 7057 win7 build . Tried resetting the monitor to default as well as windows power plan already. I know I can just turn sleep off, but I wanna try and figure out what the problem is.

Anyone experiencing similar problem?

Is this only at the login/unlock screen, or after you get to your desktop?

after I get to desktop.
The login screen has always only shown one monitor and that doesn't bother me.

Correct; I just wanted to make sure that wasn't the issue you were talking about.

I haven't experienced similar problems on my desktop, so my guess is video driver. What GPU does it have? (And have you reported the issue to MS?)
