I don’t know either Steve but maybe the answer is in Quartz Display Services. There are approximately 15 to 20 CFDisplayxxxxx calls just in the category of "Getting the Display Configuration". Maybe use one of the "Finding Displays" calls( CGGetActiveDisplayList()? ) and then one of the "Getting the Display Configuration". Maybe CGDisplayBounds() or CGDisplayScreenSize()? Again, I really don’t know but it looks like a good place to start looking. Brian S.
