Auto Keystone Correction

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

3. Projecting an Image (Basic Operation)

NOTE: When using the Auto Keystone function, heed the following:
• The vertical keystone angle can be corrected between 16 degrees upward and 16 degrees downward from level.
• The Auto Keystone correction will take effect in 2 seconds after changing the projection angle during projection.
• The left and right, or horizontal keystone distortion is not available.

Place the projector so that the lens surface is parallel to the screen.

Also, adjust the height to keep the projector level by rotating the rear feet.

TIP: 

To turn off the Auto Keystone function, from the menu select [Setup - General] 

 [Auto Keystone] and select [Off]. (

 page 

25

)

Even when the menu setting for [Auto Keystone] is turned on, [Keystone] can be adjusted manually.

NOTE: Auto and Manual Keystone correction angle could be less than 16 degrees depending on some kinds of signal and aspect
ratios.

NOTE: The Auto Keystone Correction feature can cause an image to be slightly blurred because the correction is made electronically.
