Check Remedy
(Only when projecting computer image sig-
nals)
Was the connection made while the power of
the projector or the computer was already
turned on?
If the connection is made while the power is already turned on,
the Fn key (Function key) that changes the computer's image
signal to external output may not work. Turn off the power for
the computer and the projector and then turn it back on again.
Moving images are not displayed
Check Remedy
(Only when projecting computer image sig-
nals)
Is the computer's image signal set to external
output and to output to the LCD monitor at
the same time?
Depending on the computer's specifications, moving images
may not be displayed when the computer is set to external out-
put and to the LCD monitor output at the same time.
Change it so that the image signal is set to external output only.
For the computer's specifications, see the documentation sup-
plied with the computer.

(Only when projecting computer image sig-
nals)
Are the image signals being output to the
projector?
Change it so that the image signal is set to external output, and
not just the computer's LCD monitor. For some models, when
the image signals are output externally, they no longer appear
on the LCD monitor.
For the computer's specifications, see the documentation sup-
plied with the computer.
If the connection is made while the power of the projector or the
computer is already turned on, the Fn key (Function key) that
changes the computer's image signal to external output may not
work. Turn the power for the computer and the projector off and
then back on again.
