Once you see your image, you’ll need to make certain adjustments:

■

To focus or zoom your image, see below.

■

If the image is too high or too low, you can reposition it. 
See page 39.

■

If the image isn’t square, see page 40.

■

To adjust image brightness, see page 40.

■

If a computer image displays incorrectly, see page 41.

You can make many other adjustments to the image—such as 
changing the brightness, contrast, and aspect ratio—using the 
projector’s menu system. See Chapter 4 for more information.

Rotate the focus ring to sharpen the image, and the zoom ring to 
reduce or enlarge the image.

You can also change the image size by moving the projector closer to 
or farther away from the screen. You can use the 

E-Zoom 

buttons on 

the remote control to zoom in on a portion of the image. See page 47 
for instructions.
