Correcting Keystoning

The normal projected image will have a rectangular shape.

Keystoning is when the projected image becomes trapezoidal.

Normal vs. keystoned images

Keystoning occurs when the front of the Desktop Projector is not

perpendicular to the projection screen (the vertical plane) or when

it’s not placed parallel to the floor (the horizontal plane). Key-

stoning also occurs when the projector is tilted sideways.

To correct keystoning, always make sure that the projector is at a

right angle to the screen in the horizontal plane. The projector is

properly aligned if the top and bottom of the projected image are

equal in length and parallel to the floor.
