Abstract
A video format signal generator based on a CRT controller, for producing a composite video format signal to be applied to a CRT display unit, is provided with improved circuit means for generating a clock signal to control the CRT controller whereby the timing relationships of the components of the output video format signal from the signal generator are accurately synchronized with a horizontal sync signal derived from an externally applied video signal when operating in an externally synchronized mode, whereby distortion of patterns displayed on the CRT arising from incorrect synchronization are eliminated.
