Synchronized image display and buffer swapping in a multiple display environment

Ag system and method for synchronizing image display and buffer swapping in a multiple processor-multiple display environment. In a master-slave dichotomy, one processor or system is deemed the master and the others act as slaves. The master generates signals used to control vertical retrace and buffer swapping for itself and the slaves. In addition, a synchronization signal generator is provided to synchronize a timing signal between the master and slave systems.
