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
Refer to
"Dimensions" on page 57
for the center of lens dimensions of this projector
before calculating the appropriate position.
MS619ST/MX620ST
The screen aspect ratio is 4:3 and the projected picture is 4:3
For example, if you are using an 120-inch screen, the recommended projection distance is
2422 mm and the vertical offset is 91 mm.
If your measured projection distance is 3.0 m (3000 mm), the closest match in the
"Distance from screen (mm)"
column is 3028 mm. Looking across this row shows that a
150'' (about 3.8 m) screen is required.
