ABSTRACT:
A S-correction capacitor switching apparatus for a display monitor, comprising a control unit which sets a plurality of switching devices in a conductive state immediately before the power of a display monitor is turned on, controls the conductive
onconductive state of the switching device corresponding to the horizontal frequency after the horizontal frequency of a horizontal deflection circuit set according to the frequency of a horizontal synchronizing signal of an input video signal is stabilized after the power is turned on, and connects a S-correction capacitor suitable for the frequency of the horizontal synchronizing signal of the input video signal to a deflection coil.
