Change the image with the source buttons on the remote con‐
trol, or the
button on the control panel.
Turn on the device.
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 off the computer and the projector, and then turn
them back on.
If projecting the image from outside of the correctable range,
you may not be able to correct the keystone distortion com‐
pletely. Install the projector horizontally in front of the screen as
far as possible, and then adjust the projection position using lens
shift.

Remove the lens cap.
Check the recommended projection range.
If the projector is suddenly taken from a cold environment to a
warm environment, or if sudden ambient temperature changes
occur, condensation may form on the surface of the lens, and this
may cause the images to appear fuzzy. Set the projector up in
the room about one hour before it is used. If the projector is wet
from condensation, turn off the projector, disconnect the power
cord, and leave it for a while.
Check that all the cables required for projection are securely
connected.
