BNC Connectors

Many home theater projec-
tors do not have an HD-15
connector, in which case
you can use an adapter
cable to convert from VGA
to the BNC connectors
used on the projector.
These adapter cables are readily available
through most home theater retailers and
have a VGA connector on one end and
BNC connectors on the other. The BNC
end of the cable will usually have 5
connectors (labeled R, G, B, Hsync, and
Vsync), although not all will necessarily
be needed for every display. Please refer
to your display's specifications to deter-
mine which input signals it requires.
Below is a table showing the signal mappings for each wire of the BNC cable.

If your display device requires YUV/S or
RGB/S, then this is Composite Sync, which
is sent on the H (white/gray) line.
Displays that require RGBHV or YUVHV
will require all 5 BNC connectors. Hsync is
sent on the white/gray wire, and Vsync is
sent on the yellow/black wire.
