H. Keystone
Adjust the keystone horizontally and make a more square image. Horizontal keystone is used to
correct a keystoned image shape in which the left and right borders of the image are unequal in
length, and the top and bottom are slanted to one of the sides. This is intended for use with
horizontally on-axis applications.

V. Keystone
Adjust the keystone vertically and make a more square image. Vertical keystone is used to correct
a keystoned image shape in which the left and right borders of the image are unequal in length, and
the top and bottom are slanted to one of the sides. This is intended when for use with vertically on-
axis applications.
