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.
- If you are mounting the projector from the ceiling,
use the adjustment controls on the mount at the time of
installation.
- Try to fix
the image using lens shift before adjusting the Keystone setting.
- Adjust the
image shape using the Geometry
Correction menu settings.
- Adjust the Arc
Correction setting to correct the image shape projected on a
curved surface.
