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. sComputer's documentation, under a title such as "External output" or "Connecting
an external monitor".
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

For EMP-280, the recommended projection distance for Wide ranges from 84 to 867 cm, and for Tele from
101 to 1041 cm. For EMP-260, the recommended projection distance ranges from 87 to 1050 cm.
Setup within this range. s p.60
Lower the projection angle to reduce the amount of keystone correction. s Quick Start Guide
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.
