✔ Note

These sizes are 

±

 1 inch.  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.

Example of the Multimedia projector and screen installation.  Determine picture size and projection distance as
illustrated below.
