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.
- Try to fix
the image using lens shift before adjusting the Keystone setting.
- If you
adjusted the projector height using the projector feet, press the
keystone buttons on the projector to adjust the image shape.
- Adjust the
image shape using the Keystone
menu setting.
