Epson PowerLite 7900p User Manual page 19

Ideally, you should place the projector directly in front of the center of
the screen, facing it toward the screen squarely. The base of the lens
should be at about the level of the bottom of the screen.
Projector
If you place the projector below screen level, you'll have to tilt it up by
extending its feet. This causes the image to become "keystone" shaped,
but you can correct the distortion by pressing the
projector. See page 44 for detailed information about correcting the
image shape.
For instructions on installing the projector in a permanent location,
such as a theater or conference room, see page 123.
