I have the following setup:
42" LCD @ 1920x1080 connected through HDMI (using a DVI -> HDMI adapter) to a GeForce 8500GT 24" LCD @ 1920x1080 connected through DVI to a GeForce 7300GS 22" LCD @ 1680x1050 connected through VGA to the same GeForce 7300GS
When I recover from sleep mode, or when I connect a USB device such as my phone (I already have a wireless keyboard USB and wireless mouse USB connected and functioning) windows starts making that noise to indicate a device was connected and then the noise to indicate it was disconnected and all 3 screens flick on and off. It's as if they are being disconnected from the display and reconnected.
I'm wondering if there is a problem with bandwidth on the PCI bus here. Or perhaps the problem is with my video cards not being able to handle the resolutions.
Previously, the GeForce 7300GS was running
22" LCD @ 1680x1050 connected through DVI to GeForce 7300GS 19" LCD @ 1280x1024 connected through VGA to the same GeForce 7300GS
And I didn't have the flickering problem. Now that I've introduced this new screen the problem has occurred, and as you can tell, that 7300GS has to work much harder to display 1920 + 1680 wide and 1050 + 1080 tall.
Can anyone give me some advice on possible solutions? Do we think if I buy a new video card it might solve the problem?
