Adjusting The Image Shape - Epson PowerLite 7800p Product Information Manual

EPSON PowerLite 7800p Projector

Adjusting the Image Shape

In most cases, you can maintain a rectangular image by
placing the projector directly in front of the center of the
screen with the base of the lens level with the bottom of the
screen.
Even if the projector is slightly tilted (within a range of 40° up
or down), the projector's automatic keystone correction
function detects and corrects vertical keystone distortion.
Projector tilted up Corrected image
It takes about one second after projection starts for the image
to be corrected. During this time, a vertical keystone
correction gauge appears on the screen.
If your image is still distorted, you can correct it using either
of these methods:
If the image has two parallel
sides but is wider on the top,
bottom, left, or right, you
can correct it using the
keys on the
Keystone
projector's control panel or
the Keystone menu (see
"Using Keystone
Correction" below).
If the image is trapezoid-
shaped (no two sides are
parallel), you can adjust its
shape using Quick Corner
as described below.
You cannot use both keystone correction and Quick Corner at
the same time.
