If the projected image is not evenly rectangular,
try the following solutions:
- Place the
projector directly in front of the center of the screen, facing it
squarely, if possible.
- Before
using the projector's keystone correction feature, make sure the
projector lens is in the center-top position using the lens shift
dials.
- If you
adjusted the projector height using the projector feet, press the
keystone buttons on the projector to adjust the image shape.
