If the projected image is fuzzy or blurry, try the
following solutions:
Clean the projection window.
Note: To
avoid condensation on the projection window 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.
Position
the projector so the keystone adjustment angle is not so wide that
it distorts the image.
If you are
projecting from a computer, use a lower resolution
or adjust the computer's resolution to match the projector's
native resolution, if possible.
Display a test pattern and use it to adjust the
image focus using the focus lever.
Adjust the Sharpness setting to improve image
quality.
