ABSTRACT:
A computer monitor for allowing the easy connection of computer peripherals thereto, and supplying a power supply voltage from an internal power supply therein to the computer peripherals via universal serial bus hubs. The monitor has a power supply for converting externally applied AC power into DC power; and a universal serial bus hub having at least one upstream port and at least two downstream ports; wherein the upstream port is electrically connected in communication with the computer system, and the downstream ports receive DC power in response for a power switching signal in accordance with power supply control information from the computer system through the upstream port to selectively provide the DC power to external devices connected therewith in response to the power switching signal.
