Keystone Adjustment

What is Keystone?

"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.

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.

Keystone Adjustment

How to Correct Keystone

If the image looks trapezoidal with the base or the top larger, use the Keystone Adjustment wheel on the top of the HP4 projector to adjust the image until the projection screen is a squared image.
