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 46 and in the 
Service section of our website.
