placing the projector directly in front of the center of the screen with
the base of the lens level with the bottom of the screen.
If the projector is slightly tilted (within a range of 30° up or down),

Keystone keys on the projector’s control panel or the
projector’s Keystone menu (see “Using Keystone Correction” on
