I've got a dell computer that I just reinstalled the OS (Windows XP SP3) on and didn't have the driver disk so I downloaded most of the drivers from dell.com. I tried to hook up dual-monitors, but it won't let me. I can show the screen on one or the other or both, but I can't use the second to extend the first. If I do it to show on both screens it just show the same screen on both monitors. I'm guessing there is a driver like NVIDIA Dualview that I need to download but I haven't been able to find anywhere to download it. Thanks for the help.
