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?
On a lot of Dell Laptops, the way you set up the dual-view/shared desktop is (from memory so bear with me!) by right-clicking on the desktop, going to display options, dual view (or clone desktop) there.
If the monitor's sufficiently old, you may have to explicitly tell Window's it's there.
Theres a slim chance it only supports mirroring. Did you check on the Dell Talk forums?
