Keystoning - making the image a perfect rectangle
There are four different ways to correct keystoning:
1)Adjust vertical or horizontal projection angle. (Best method)
2)Use vertical digital keystone correction with projector menu, keypad or remote. (Most projectors have this feature.)
3)Use horizontal digital keystone correction with projector menu, keypad, or remote. (Some projectors have this feature.)
4)Use lens shift in the projector menu. (Some projectors have this feature)
