I have recently discovered the world of Dual Screens and have been having a little trouble with my Q35 Express Chipset. I only had one VGA port so I purchased a USB to VGA converter plugged my secondary screen in and everything worked great. I then noticed that the secondary screen quality was poor compared to the primary. I then checked the Graphics Media Acclerator > Display Devices but I only have the option for Single Display. I find that starnge as I can see both monitors in the normal display properties menu.
I have tried everything I can think of, updating all drivers etc. I know the Secondary screen is capble of a better display as I have set it to primary and seen the improvement, but then I loose qulaity on the other screen.
