Raising the projector causes the image to distort or

"keystone," but you can manually correct the shape as

described in the next section.

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

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" on page 7).

❏ If the image has no parallel

sides, you can adjust its

shape using Quick Corner

(see page 8).

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

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.
