Abstract

본 발명은 모니터에 관한 것으로서, 특히, 모니터의 수평 동기신호 또는 수직 동기신호중 하나 이상이 입력되지 않을 때 뮤트신호가 발생되어 비디오 신호가 화면에 디스플레이되는 것을 방지함으로써, 모니터의 스포트 및 노이즈를 제거시켜 화질을 상승시킬 수 잇는 모니터의 뮤트신호 발생회로에 관한 것이다.The present invention relates to a monitor. In particular, a mute signal is generated when one or more of a horizontal sync signal or a vertical sync signal of a monitor is not input to prevent a video signal from being displayed on a screen, thereby eliminating spots and noise of the monitor. The present invention relates to a mute signal generating circuit of a monitor capable of increasing image quality.

이와같은 본 발명은 컴퓨터의 마이크로 프러세서에서 출력되는 수평 동기신호 및 수직 동기신호중 어느 하나 이상이 입력되지 않은 경우 비디오 보오드에서 주사되는 비디오 신호의 출력을 제거시키는 뮤트신호 발생수단이 메인 보오드에 더 포함된다.The present invention further includes a mute signal generating means for removing the output of the video signal scanned from the video board in the main board when at least one of the horizontal synchronizing signal and the vertical synchronizing signal output from the computer microprocessor is not input. do.
