NEC VT440 Service Manual page 24

When using a Macintosh computer with the projector, set the DIP
switches of the supplied pin adapter according to your resolution.
After setting, restart your Macintosh computer.
See the following pages for setting of the DIP switches.
• When using with a Macintosh, SVGA(800
XGA(1024 768 : VT540) is recommended if your Macintosh
supports this mode.
• When using with a Macintosh PowerBook, output may not be
set to 800 600 unless "mirroring" is off on your PowerBook.
Refer to owner's manual supplied with your Macintosh com-
puter for mirroring.
NOTE: A Video Adapter cable manufactured by Apple Computer is
needed for a PowerBook which does not have a mini D-Sub 15-pin
connector.
