If you can't connect the projector's computer cable to your
PowerBook, you may need to use a Macintosh adapter
(available from Apple).
Remove the small cover on the
Macintosh adapter and set its DIP
switches according to the resolution
you want to use (such as 16-inch
mode). See your PowerBook
documentation for instructions.
Connect the small end of
the Macintosh adapter to
the computer cable.
Connect the computer
cable (with the
Macintosh adapter
attached) to the
video-out port on your
PowerBook.
If your PowerBook requires a video-out cable, connect
the smaller end of the video-out cable to the video-out
port on the back of the PowerBook. Connect the other
end to the Macintosh adapter on the end of the
computer cable.
3. Tighten the screws on all connectors.
