Are the image signals being output to the
projector?
If the image signals are only being output to the computer's LCD monitor or to the accessory
monitor, you need to change the output to an external destination as well as the computer's own
monitor. For some computer models, when the image signals are output externally, they no longer
appear on the LCD monitor or accessory monitor.
Computer documentation, under a title such as "External output" or "Connecting an external
monitor"
If the connection is made while the power is already turned on, the function [Fn] key that switches
the computer's video signal to external output may not work. Turn the power for the projector and
the computer off and then back on again. p.36, p.40
