Keystone Adjustments
What is Keystoning?
Keystoning occurs when a projector is aligned non-perpendicularly to a screen, or
when the projection screen has an angled surface. The image that results from one of
these misalignments will look trapezoidal rather than square.

Digital Keystone Adjustments
By adding a special, selectable algorithm to the scaling, the projector is able to alter
the image before it reaches the projection lens. The result is a squared image, even at
an angle.
