EPSON PowerLite 7700p Projector
If you place the projector level with the bottom of the screen,
the image will be square and you won't have to adjust it. If
you place the projector higher than the bottom of the screen,
the image will still be square, but you won't be able to fill the
whole screen with the image.
The projector can be installed for three different viewing
setups: front projection, ceiling mounting, or rear projection
onto a semi-transparent screen, as shown:
front projection
To project from overhead, you'll need to select
projector's Advanced menu. To project from the rear, select
.
Rear Proj
If you're ceiling-mounting the projector and you place it
above screen level, you'll have to tilt it down to position the
image on-screen. This causes the image to lose its square
shape. You can then correct the distortion by using the
Keystone function in the projector's menu system or by using
the
button on the projector's control panel.
Keystone
If you place the projector's lens so it's level with the top of the
screen, the image will be square and you won't have to adjust
it. If you place the lens lower than the top of the screen, you'll
have to tilt the projector upward if you want to fill the whole
screen with the image.

Image Size and Projection Distance
Use the tables below to estimate how far to place the projector
from the screen. Since the size of the image can be changed by
rotating the zoom ring, a range of distance is given for each
screen size.
Note that if you tilt the projector upward by extending the
feet or use electronic keystone correction, your image size may
vary.
