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
NOTE:
1) The maximum keystone angle that can be corrected is 30 degrees upward
and 30 degrees downward with the projector placed horizontally on the ground
plane.
2) When "Resolution" is set to "Native", this feature is not available, and the
stored settings and adjustments are invalid.
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.

Move the slide bar to the right to increase the color temperature for a
bluish image; to the left to decrease it for a reddish image.
