Introduction

An LCD monitor is designed for users to get higher image quality and in the mean-time less power consumption than CRT monitor. Usually, an LCD monitor system is composed of a conversion board and a display panel. The conversion board is for input signal processing and for output format display, and the display panel performs different resolution according to input signal resolution set by the user.
