For each corner, apply horizontal and / or vertical correction as necessary to restore the 
rectangular shape of the image.

Top Right Corner correction
Notes
  Corner corrections provide a simple 
setup for awkward installations and 
irregular shaped screens that may 
distort the image. To apply a similar 
(but less exible) correction, while 
preserving the original aspect ratio 
of the image, use the Keystone 
menu.
