12 Positioning your projector
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format each factors
in the projected image size.
Projection dimensions
• The screen aspect ratio is 16:9 and the projected picture is in a 16:9 aspect ratio
For example, if you are using a 120-inch screen, the recommended projection distance is 4184 mm.
If your measured projection distance is 520 cm, the closest match in the
"Distance from screen (mm)"
column is 5230 mm. Looking across this row shows that a 150'' (about 3.81 m) screen is required.
