I have a problem. My laptop must at times be hooked to a projector and I can only make it work by using the projector as a second monitor (image is off the screen of the laptop display and the projector has a seperate image [monitor 1 is the display while monitor 2 is the projector]). How can I set it up to have the display and projector show the same image instead of splitting between monitor 1 and 2? It is a Dell using windows XP. Thanks.
