• The result of keystone adjustment is memorized. If the projector installation
position is the same as before, keystone adjustment is not required.

image may look different from the original one.
• The aspect ratio of the image may change when keystone is adjusted.
• Keystone can be adjusted vertically and horizontally within the range of +/-20
degrees. The amount of adjustment varies depending on the combination of the

position.
