A-6 Connector Pin Assignments

VGA Interface Connector

Video signals are output from the system board through a VGA interface connector, which
is a 15-pin, D-subconnector (VESA VS890803-2) located at the rear of the system unit.
Figure A-6 and Table A-5 show the connector pin locations and pin assignments.
