Keystone Adjustments

Digital Keystone Adjustments

By adding a special, selectable, algorithm to the scaling, some new projectors

are able to alter the image before it reaches the projection lens. The result is a

squared image, even at an angle.

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.
