Digital Keystone Correction
Keystoning is when the projected image is noticeably wider on either the top or bottom. There are two
ways to correct this:
1. Press Menu on the remote control or projector, then select the Display menu (first menu bar button
on the left), then adjust the sliding bar labeled Keystone, as needed.
2. Use the Keystone buttons on the external control pad. Pressing the + button will correct
keystoning at the top of the image. Pressing the - button will correct keystoning at the bottom
of the image.

Note: These sizes are
±
1%. This is due to variations in the manufacture of the lens. If you are close to one
of the endpoints you should verify with your unit that the image is the proper size at the proper distance.
