You
can use the projector's keystone correction buttons to correct the
shape of an image that is unevenly rectangular on the sides.
Note: You can
use the keystone buttons to correct the image up to ± 3°
horizontally or vertically. If the projector is
mounted on the wall, use the adjustment dials on the wall mount to
correct the screen image before using any other digital correction
methods.
Note: You
cannot combine keystone correction with other correction methods at
the same time.
Note: If you
change the Screen Type setting or
adjust the image position, your image adjustments are
reset.
