Is the projector at the correct
distance?
The recommended distance from the projector to the screen is within
87–1365 cm (2.9–44.8 ft.) for a screen size of 16:9, and 108–1672 cm

value too large?
Decrease the projection angle to reduce the amount of keystone
correction.

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
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.
