Video Connector

You can attach a VGA-compatible monitor to the system’s integrated video controller using a

15-pin high-density D-subminiature connector. Figure B-4 illustrates the pin numbers for the video connector and Table B-4 defines the pin assignments for the connector.

NOTE: Installing a video card automatically disables the system's integrated video controller.
