3. Projecting an Image (Basic Operation)

￿Correcting Keystone Distortion

Auto Keystone Correction

The Auto Keystone correction feature will correct vertical distortion of a projected image on the screen. No special operation required. Just put the projector on a flat surface.

Manual Keystone Correction

You can also correct keystone distortion manually.

To do so:

1.Extend the Adjustable Tilt Foot to adjust the height of a projected image. See page 31.

The Keystone screen will be displayed on the screen.

If the Keystone screen disappears, press the 3D REFORM button once to display the Keystone screen again.

2.Align the left (or right) side of the screen with the left (or right) side of the projected image.

Use the shorter side of the projected image as the base.

In the right example, use the left side as the base.

NOTE: When "Manual" is selected in "Keystone" from the menu, project an image adjusting projector position so that the screen is smaller than the area of the projected image. See page 90 for selecting "Manual" in "Keystone".
