The distance from the projector lens to the screen, the zoom setting (if available), and the
video format each factors in the projected image size.

MS517/MX518/MS517F/MX518F
The screen aspect ratio is 4:3 and the projected picture is 4:3
For example, if you are using a 120-inch screen, the average projection distance is 5040
mm and with a vertical offset of 274 mm.
If your measured projection distance is 5.0 m (5000 mm), the closest match in the
column is 5040 mm. Looking across this row shows that a 120''
(about 3.0 m) screen is required.
