Connecting the projector to a computer

NOTE: Many laptop computers do not automatically turn on their external video port when a sec- ondary display device such as a projector is connected. Refer to your computer manual for the command that activates the exter- nal video port. Activation com- mands for some laptop computers are listed in the Appendix of this manual on page 44 and in the Technical Support section of our website.

NOTE: If you are connecting an older Macintosh computer that does not have a 15-pin connector, you must use a Mac adaptor between the computer and the projector. See “Optional Accesso- ries” on page 43.
