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 as follows:

❏ 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 no two sides of the image

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.

❏ Press the

Menu

button on the remote control and select the

Setting

menu. From the Setting menu, select

H/V-

Keystone

in the Keystone menu. Select

V-Keystone

(for

vertical keystone distortion) or

H-Keystone

(for horizontal

keystone distortion). Use the

pointer button on the

remote control to adjust the keystone setting as needed.

Using Quick Corner

When no two sides of the image are parallel, use Use Quick
Corner to correct it.

Menu

button.

2. Select the

Setting

menu.

3. From the Setting menu, select

Keystone

.

4. Select

Quick Corner

.

You see this screen:

5. Press the

Enter

button to select

the corner you want to adjust.

6. Use the

the remote control (or the
arrow buttons on the projector)
to adjust the shape.

7. Repeat steps 5 and 6 as needed

to adjust the remaining corners.

8. When done, press the

ESC

button to exit the menu system.

If

Quick Corner

remains selected in the Keystone menu, the

Quick Corner screen appears whenever you press the
projector’s

Keystone

buttons. You can then follow steps 5

Correcting Computer Images

If you’ve connected a
computer and the image
doesn’t look right or fit
properly on the screen, press
the

Auto

button on the

remote control (or the

Auto/Enter

button on the

projector’s control panel).

This automatically resets the projector’s tracking, sync,
resolution, and position settings.

Note: You must be projecting an image for this button to have
any effect. The

Auto

button works only with computer images.

The projector should automatically detect the correct source.
However, if the image color doesn’t look right even after you
press the

Auto

button, try pressing the correct source button

to select the source. See page 5 for details.

If vertical stripes appear in the projected image and the

Auto

button doesn’t correct the problem, hold down the

Shift

button on the projector’s control panel while pressing either
the

Tracking +

or the

Tracking –

button.

If the image appears fuzzy or flickers and the

Auto

button

doesn’t correct the problem, hold down the

Shift

button while

pressing either the

Sync +

or

Sync –

button.
