Hello wise [H] members, I was hoping you could help me with an issue I have. I have an Acer AL2223W 22 in. wide screen display, a Hyundai L90D+ 19 in. display, and a 7800 GTX. My problem is when I try to use both displays using Dualview, my Acer screen becomes messed up at is native resolution (1680 x 1050). I guess could post a screen if necessary, but it draws lines across the entire screen. It only works at 1440 x 900. Any ideas on why this would happen only on my Acer display? Thanks in advance.
