I'm hooking up an old ibook to a projector. When working on the screen of the iBook to open browser windows and apps to display video on the projector, The program always appears far off the screen. Displays are mirrored so the program isn't appearing half on the projector or anything. Is there a setting or a certain resolution my ibook screen must be at so my windows won't keep getting clipped. It really slows down the screenings.
