I have an issue with my Acer P221W monitor going black when I switch user profiles on my Win 7 PC. It only happens on random occasions but it's enough to be frustrating; a few times a week at least, sometimes once a day depending how much use the PC gets throughout the day.

but at that point I thought it was a problem with the OS.
Last night this happened again so I decided to unplug the monitor cable going into the video card (Radeon 4870) and plug it back in. Sure enough, when I plugged it back in the monitor came back to life. So now I'm wondering if it's hardware related. All my video drivers are up date and besides, this has been happening for quite some time (more frequently lately however). There are no Win 7 64-bit drivers for the monitor and certainly no firmware updates.
I'm at a loss as to what to do.
