Dual Monitor Problem


I'm having problems with my dual monitor setup. Before I was using a matrox dual head video card on Windows XP OS with 2 CRT monitors. Now I'm using two 22'' LCDs on Windows Vista Ultimate 64bit, with a Nividia 8800 GT video card. The problem is, when ever the machine goes goes into sleep mode and I have Quotetracker and Interactive Brokers active, and I awake the computer, the monitors will flicker every 3 seconds, showing my desktop, then going to black. And it repeats this until you restart the computer. Apparently there are issues with Vista and dual monitors, because I did a search and there are many other people out there with similiar problems. In attempt to solve the problem, I have changed the power settings (under screen saver settings) to never allow the computer to go into sleep mode and for the monitors to never go into sleep mode. Also I set the screen saver wait time to 9999 minutes. The problem is probably Vista related, but hopefully this will work for now.

I have dual monitor setup with the 8800 nvidia and have no problems.
What drivers are you using ? Vista built in drivers or the nvidia drivers ? If the one's from vista, uninstall and install the nvidia one's. If your using the nvidia contact them as your card may be going bad.

Good luck.

I have nividia drivers. The video card is brand new. I think I fixed the problem, which was the computer going into sleep mode, apparently vista has some problems with this.

Yes, me as well, nothing to do with NVIDIA drivers in my caes, I had the latest. Anybody have answers to this?
Matrox is brutal with their "support". You can't even register the product to get support online...

My monitor problem is vista related, and a guy on youtube found a temporary fix.
use task manager to kill explorer.exe on the processes tab and it will be ok for a random amount of time (use file -> run and put in
explorer
and hit ok to restart explorer.
SP1 makes it worse.
