Adjusting an image for keystone correction

Keystone is typically caused by tilting the projector in relation to the screen so the lens surface and
screen are no longer parallel to each other. Vertical keystone is used to correct a keystoned image
shape in which the top and bottom borders of the image are unequal in length, and both sides of
the image are inclined toward the top or bottom edge.
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.
All settings to adjust keystone are in the Geometry Correction submenu. Brightness
Uniformity, Edge Blending and Black Level Blending should be disabled before performing
Keystone adjustments.
1. Enable keystone adjustments by selecting Keystone from the Geometry Correction drop
down list. This enables the controls for performing 1D or 2D keystone adjustments.
2. Select a test pattern. Christie recommends using the Grid test pattern.
