Abstract
A display monitor includes a conventional CRT and associated display drive circuitry together with conventional horizontal and vertical deflection systems. A high voltage system is operated in response to the horizontal deflection system to produce a CRT accelerating potential. A display size control responds to changes of high voltage system current to produce an error signal which is used to produce compensating amplitude changes of vertical and horizontal deflection currents in order to maintain substantially constant image size.
