Check Remedy
Is the power of the connected computer or video equipment turned
on?
Turn the power on for the equipment.
Are the image signals being output to the projector?
(Only when projecting images from a laptop computer or a
computer with a built-in LCD screen)
If the image signals are only being output to the computer's LCD monitor or accessory monitor, change the output so
that the image signals are also output externally. For some computer models, when the image signals are output
externally, they no longer appear on the LCD monitor or accessory monitor.
If the connection is made while the power of the projector or 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 projector and computer off and then
back on again.

Has condensation formed on the lens? 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 condensation forms on the lens, turn the projector off and
wait for the condensation to disappear.
Interference or distortion appear in images
Check Remedy
Is the image signal format setting correct?
(Only when projecting images from a video source)
