allows you to connect an LCD monitor. The DVI connector provides a
high-speed digital interconnection between the computer and its display
device. To connect a LCD monitor, simply plug your monitor cable into
the DVI connector on the mainboard, and make sure that the other end of
the cable is properly connected to your monitor. (refer to your monitor
