You can correct the distortion using the
function in the
Keystone
projector's menu system (see page 123) or the keystone buttons on the
projector's control panel.
If you place the projector so that the base of the lens is level with the
bottom of the screen, the image should be square and you won't have
to adjust it. If you place the lens lower than the bottom of the screen,
you'll have to tilt the projector upward if you want to fill the whole
screen with the image.
