The DVI-D cable supplied with this monitor is for digital-to-digital
connection only. Your computer must have a DVI-compatible
graphics card installed for use with this cable. When connecting
the DVI-D signal cable to the DVI connector on the monitor, you
must connect the other end of the DVI-D cable to the DVI connector
on the computer. Connect one end of the power cable to the back
of the monitor, and the other end to an electrical wall outlet.
