I have attached dual monitors to a Dell Optiplex 3010, the monitors are Dell P2213. I have tried one on vga and one on dvi,and tried changing it to dvi in menu settings, that did not resolve the issue. I have tried windows key + p, I've tried connecting the second monitor via usb and it continues to show the same thing on both screens. I do not have the extend option when I go into the display function, nor do I get the option when I right click on my desktop. Both monitors are showing up as Generic VGA monitors. HELP
