Projection Operations

Keystone Correction (KEYSTONE)

When the projector is at an angle to the screen it is projecting on, the projected image may
have different length left and right edges, or top and bottom edges. This phenomenon is
called, "keystoning". This projector comes with functions for automatic as well as manual
keystone correction, which provides a regularly shaped projected image.
Keystone correction (auto or manual) can cause dustortion of the projected image. If this
happens try moving the screen and/or projector so they are oriented close to the
configuration shown under "Setting Up the Projector" on page 28.
Keystone correction can cause the corrected image to be smaller than the original
(uncorrected) image.
Automatic Keystone Correction
Automatic keystone correction correct the image to counteract the effects of vertical
keystoning.
Performing auto keystone correction causes the message "Auto Keystone Corrected." to appear
in the center of the projected image.
