Dell PowerEdge 1400SC - Manual (Page 74)

B-8 User’s Guide
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 B-6 illustrates the pin numbers for the video connector,
and Table B-5 lists and defines the pin assignments and interface signals for the video
connector.
