Positioning your projector14
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.
If you need a 4:3 screen to project a 4:3 picture and your measured projection distance is
3000 mm, please refer to Table A1
on page 14. The closest match in the "Distance from
screen (mm)" column is 2933 mm. Looking across this row shows that a 80'' (about 2.0 m)
screen is required.
Projection dimensions
Refer to "Dimensions" on page 58 for the center of lens dimensions of this projector before
