I worked on a Flight Simulator project that used RGB splitting for three monitors. In fact we had 4 monitors running off of the one Amiga. We had graphics cards that gave us a convenient byte-per-pixel display for polygons and scaled images on the main screen, and three small Mono monitors for instrument display. The instrument displays were each drawn into a single bitplane and a copper-list-of-doom mixed them with a noise bitmap and other failure modes to make a single rgb image which drove the three mono displays. The screens would then flicker, roll, and fade according to their damage status and all we had to worry about is drawing to the bitmap.
