I have a Dell Inspiron 1100 laptop and want to use multiscreen. I am using windows XP and have an older monitor to use. I was reading instructions from the internet about it and when I connected the laptop to the old screen and restarted the image came up on both screens. When I went to display properties, setting, only one monitor appeared instead of two. This meant I couldn't use dualview (drag from one screen to another). Any suggestions?
