If the image signals are only being output to the computer's LCD monitor or to the accessory

monitor. For some computer models, when the image signals are output externally, they no longer
appear on the LCD monitor or accessory monitor.

The recommended projection distance range is 100–1210 cm (3.2–39.7 ft.). Set the projector up so
sp.16
that it is within this range.
Decrease 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 approximately one hour before it
is to be used. If condensation forms on the lens, turn the power off and wait for the condensation to
disappear.
