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.
For example, if you are using a 120-inch, 4:3-aspect-ratio screen and the projected picture is
16:10, please refer to Table B2
on page 16, the recommended projection distance is 1192 mm
and the vertical offset is 76 mm.
If you need a 16:9 screen to project a 16:9 picture and your measured projection distance is
1.5 m (1500 mm), please refer to Table A1
on page 14. The closest match in the "(b) Distance
from screen" column is 1623 mm. Looking across this row shows that a 150'' (about 3.8 m)
screen is required.
