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.
