Projector-To-Screen Distance - 3M MP8780 Operator's Manual

A.3

Projector-to-Screen Distance

Example of the Multimedia projector and screen installation. Determine picture size and projection distance as
shown below.
These sizes are ± 1%. This is due to variations in the manufacture of the lens. If you are close to one of the
endpoints you should verify with your unit that the image is the proper size at the proper distance.
The image can be shifted up or down without distortion (keystoning) by turning the Image Shift Control knob on
the top of the projector.
