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.

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

Keystone

keys on the

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.

Using Keystone Correction

To adjust your image when it is wider on one side, do one of
the following:

❏ Look at the shapes of the icons on the

projector’s four

Keystone

buttons.

Press the button whose icon is the
opposite shape of your screen image.
Continue pressing the button until
you are satisfied with the shape of the
image.

Note: The image will be slightly shorter after adjusting. If it’s
important to maintain the correct aspect ratio, use the menu
system to perform keystone correction, as described below,
then adjust the Height setting as needed.
