The circuit arrangement is such that each graphic processor has a clock, and a genlock input or output. The clock inputs of all the graphic processors are connected to a common oscillator, or have individual oscillators with one of the graphic processors arranged as a master. The master uses its genlock signal as a controller genlock input to the remaining slave processors. An Independent claim is made for a personal computer (PC) with several graphic processors for simultaneous control of more than one monitor, where the master graphics card has a clock input from a reference oscillator, with the remaining slave graphics cards clocked via a voltage controlled oscillator in a phase lock loop (PLL) circuit.
