Positioning your projector
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
MX731
• The screen aspect ratio is 4:3 and the projected picture is in a 4:3 aspect ratio
For example, if you are using a 120-inch screen, the recommended projection distance is 4243 mm.
If your measured projection distance is 5000 mm, the closest match in the
"Projection distance (m)"
col-
umn is 4950 mm. Looking across this row shows that a 140'' (about 3.6 m) screen is required.
