Adjusting the projected image
Adjusting the projection angle
The projector is equipped with an adjuster foot. It changes the image height and vertical
projection angle. Screw the adjuster foot to fine tune the angle until the image is positioned
where you want it.
If the projector is not placed on a flat surface or the screen and the projector are not
perpendicular to each other, the projected image becomes trapezoidal. To correct this
situation, see "Correcting keystone" on page 23 for details.
