A method for detecting and separating vertical and horizontal synchronous signals from a computer system. The input forms of the vertical and horizontal synchronous signals from the computer system are detected by scanning a vertical synchronous signal terminal, a horizontal/composite
A stabilizing circuit for stabilizing a horizontal transistor of a video display device. The stabilizing circuit includes a transient state detector for detecting a transient state of a phase locked loop circuit in a horizontal drive circuit due to a change in an operation mode of a vide
