Displaying and Adjusting the Image 21

Focusing and Zooming Your Image

Turn the focus ring on the projector to sharpen the image.

Turn the zoom ring on the projector to reduce or enlarge the image.

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.

See page 29 for instructions.

Adjusting the Image Shape

In most cases, you can maintain a square or 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 30° up or

down), the projector has an automatic keystone correction function

that 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 the Keystone

buttons on the projector’s control panel or the projector’s Setting

menu.
