Extra-monitor control circuit and transmission system for monitor
An extra-monitor control circuit and transmission system for monitor includes an extra-monitor control circuit system having a scaler circuit, an On Screen Display (OSD) circuit, and a DC/DC converting circuit provided thereon. The extra-monitor control circuit system is located at a position outside a monitor and connected to the monitor via a transmission system consisting one single cable and connectors thereof. The one single cable and the connectors thereof transmit both signals and power to the monitor from a personal computer (PC) host to thereby reduce the monitor manufacturing cost and eliminate the problems of distorted signals and signal compatibility.
1 . An extra-monitor control circuit and transmission system for monitor, comprising:
an extra-monitor control circuit system provided at a position outside a monitor;
a DC/DC converting circuit adapted to convert power supplied from a power supply of a personal computer (PC) host and supply the converted power to said monitor; and
a transmission system including one single cable and connectors thereof for connecting said PC host to said monitor to transmit both signals and power to said monitor from said PC host.
