If the projected image is fuzzy or blurry, try the
following solutions:
Adjust the
image focus.
Check the lens for condensation.
Note: To avoid
condensation on the lens after bringing the projector in from a
cold environment, let the projector warm up to room temperature
before using it.
Position
the projector close enough to the screen, and directly in front of
it.
If you are
projecting from a computer, use a lower resolution.
Turn off any keystone correction and disable the Quick Corner setting.
