Abstract

A video display has microcomputer control via a data bus and comprises a first sync generator coupled to the data bus for control by data thereon. A second sync generator is without controllable coupling to the data bus. A deflection amplifier is coupled to a deflection coil for generating a deflection current therein. A circuit for controlling the second sync generator is coupled to the first sync generator and is responsive to a digitally controlled signal therefrom. The second generator output signal is coupled to the deflection amplifier for deflection generation responsive to the digitally controlled signal.
