PREPARATION

Projection Distance per Screen Size

Place the projector on a sturdy, level surface, together with the PC or audio/video

source.

Place the projector an appropriate distance away from the screen. The distance

between the projector and the screen determines the actual size of the image.

Position the projector so that the lens is at a right angle to the screen. If the

projector is not at a right angle, the projected image will look distorted. To correct the

distortion, use the Keystone function. (See page 36)
