Obtaining a preferred projected image size
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.
Projection dimensions
Refer to

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.
