Positioning your projector16
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 "Dimensions" on page 70 for the center of lens dimensions of this projector
before calculating the appropriate position.

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
"Projection distance (mm)" column is 5040 mm. Looking across this row shows that a 120''
(about 3.0 m) screen is required.
