Keystone
This feature corrects the keystone (trapezoidal) distortion to make
the top of the screen longer or shorter to be the same as the bottom.
Use the
ᮤ
or
ᮣ
buttons on the slide bar to correct the keystone
(trapezoidal) distortion.
Keystone distortion
Normal
NOTE: The maximum keystone angle that can be corrected is 40 degrees up-
ward and 20 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.

spectively.
