3. If the projector is not level, rotate the 
foot at the back of the projector.
If the image is no longer rectangular after 
raising it, see the next section.
Correcting Computer Images
If you’ve connected a computer and the image doesn’t look 
right, or it doesn’t fit properly on the screen, press the 
Auto 
button on the remote control or the 
Enter button on the 
projector. This automatically resets the projector’s tracking, 
sync, resolution, and position settings. (You must be projecting 
an image for this button to have any effect.)
Note:
If the 
Auto Setup option in the Signal menu is set to OFF, the 
Auto function will not work.
Adjusting the Image Shape
The projector automatically corrects images that are distorted 
when the projector is tilted up or down (up to 30°). The 
Keystone window appears on the screen while the projector 
makes the correction. 
If the projected image still isn’t rectangular, try the following:
❏ If your image looks like   or  , you’ve placed the 
projector off to one side of the screen, at an angle. Move it 
directly in front of the center of the screen, facing the screen 
squarely.
❏ If your image looks like   or  , you may need to 
manually adjust the keystone correction value. Follow the 
instructions below.
Using Keystone Correction
To adjust your image when it is wider on the top or bottom, do 
one of the following:
❏ Press one of the two triangular buttons on the projector’s 
control panel, as shown below. Continue pressing the button 
until you are satisfied with the shape of the image.
❏ Or press the 
Menu button on the remote control or 
projector, select the 
Setting menu, and press Enter. From 
the Setting menu, select 
Keystone and press Enter. Use the 
pointer button on the remote control to adjust the 
keystone setting as needed. The keystone setting is adjustable 
from –65 to +65. These numbers represent a range of –30° 
to +30° of angle change; adjustments are made in steps of 
0.5°.
After correction, your image will be slightly smaller.
Note:
If the image becomes uneven, try decreasing the 
Sharpness setting 
in the Image menu. 
Resizing Video images
You can use the Resize button on the remote control to adjust 
how an image fits into the display area. 
For video images, press 
Resize to switch the aspect ratio 
between 4:3 and 16:9. This lets you play certain digital video 
images or movies recorded on certain DVDs in 16:9 widescreen 
format.
For computer images, resizing is normally unnecessary, since 
the projector automatically resizes the image to make the best 
use of the display area. If you press the 
Resize button on the 
projector or remote control, the projector displays the image at 
the output resolution of the computer (which makes the image 
larger or smaller, depending on its resolution). If the resolution 
of the image is the same as the projector’s (1024 
×  768), 
pressing 
Resize has no effect.
