Video Connector
The system uses a 15-pin high-density D-subminiature connector on the back panel for attaching a video graphics array
(VGA)-compatible monitor to your system. 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. Figure 6,
Pin Numbers for the Video Connector, illustrates the pin numbers for the video connector, and Table 5, Pin
Assignments for the Video Connector, lists and defines the pin assignments and interface signals for the video
connector.
