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.

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.
