Video Connector

The system uses a 15-pin high-density D-subminiature
connector on the back panel for attaching a video graph-
ics array (VGA)-compatible monitor to your computer.
The video circuitry on the system board synchronizes the
signals that drive the red, green, and blue electron guns in
the monitor.
NOTE: Installing a video card automatically disables the
system's built-in video subsystem.
If you reconfigure your hardware, you may need pin
number and signal information for the video connector.
