NOTE: When “sRGB”, “Graphic”, “Video” or “Movie” is selected, the bright-
ness decreases slightly when compared to “Presentation”. This is not a mal-
function.
Correcting Vertical Keystone Distortion [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 F or E buttons on the slide bar to correct the keystone (trap-
ezoidal) distortion.
NOTE: The keystone angle can be corrected between 30 degrees upward and 30
degrees downward at a 0 degree-projection angle. 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.
Saving Vertical Keystone Correction [Keystone Save]
This option enables you to save your current keystone settings.
Saving your change once affects all sources. The changes are saved
when the projector is off.
