Problem Solving
Check
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
Images are fuzzy or out of focus
Check
Is the focus adjusted correctly?
Is the projector at the correct distance?
Is the Keystone adjustment value too large?
Has condensation formed on the lens?
Interference or distortion appear in images
Check
Is the image signal format setting correct?
Only when projecting images from a video source
Are the cables connected correctly?
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. For more information, see your computer's documentation.
If the connection is made while the power of the projector or computer is already turned on, the
function [Fn] 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.

Press the [Focus] button on the remote control to adjust the focus.
Is it projecting outside of the recommended projection distance range?
Setup within the recommended range.
Lower the projection angle to reduce the amount of keystone correction.
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.
Change the setting according to the signal for the connected equipment. s Signal Menu - Video
