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.
1. Press the
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 pointer button on
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
through 8 above to correct the shape of your image, or press
ESC to exit Quick Corner.
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.
