Display apparatus for computer system

摘要

A computer monitor in which USB devices connected thereto can be operated with a host power supply voltage provided through host-connected hub ports, even though a power supply voltage from a power supply of the monitor has been cut off. The monitor detects when a power supply voltage to USB devices connected thereto is beyond a rated voltage, and shuts off an abnormal voltage of more than the rated voltage to the USB devices so as to prevent them from being damaged due to the abnormal voltage.
