Image Options
Keystone
Keystone distortion Normal
NOTE: The maximum keystone angle that can be corrected is 30 degrees up-
ward and 30 degrees downward with the projector placed horizontally on the
ground plane.
Depending on the type of graphics being used, the picture may get
blurred or keystone correction may not be possible when excessive
keystone correction is used.
The idea is, the closer you are to native resolution, the better image
you will see.
