An extra-monitor control circuit system for monitor includes one or more of an OSD circuit, a scaler circuit, and an A/D converting circuit, and a DC/DC converting circuit. The extra-monitor control circuit system is located at a position outside a monitor, and the DC/DC converting circuit converts power supplied from a power supply of a PC host and supplies the converted power to the monitor. The extra-monitor control circuit system may be in the form of an independent unit adapted to insert into an expansion slot on the PC host, or integrated into a PC graphic card. With the extra-monitor control circuit system, the monitor can be manufactured at a reduced cost and the problems of signal distortion and compatibility can be avoided.
