Use the 
Zoom
 buttons on the projector or remote to reduce or 
enlarge the image. Press the 
W
button on the projector or the 
top zoom button on the remote to increase the size, or the 
T
button on the projector or bottom zoom button on the 
remote to decrease it. 
If the image still isn’t large enough, you may need to move the 
projector farther away from the screen. You can also use the 
E-Zoom
 buttons on the remote control to zoom in on a 
portion of the image. 
Adjusting the Height of Your Image
If the image is too low on the screen, you can raise it by 
adjusting the front foot:
1. Stand behind the projector. Press up on the blue foot 
release lever and lift the front of the projector.
2. Once the image is positioned where you want it, release the 
lever to lock the foot in position.
3. If necessary, you can fine-tune the height by turning the 
projector’s rear feet.
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 45° 
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
 
buttons on the projector’s 
control panel or the Keystone 
menu (see the next section).
❏ If the image has no parallel 
sides, you can adjust its shape 
using Quick Corner
 (see 
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 the 
following:
❏ Look at the shapes of the icons on the projector’s four 
keystone buttons. Press the button whose icon is the 
opposite of the shape of your screen image. Continue 
pressing the button until you are satisfied with the 
shape of the image.
