Positioning your projector 15
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.
MX850UST: For example, if you are using an 120-inch screen, the recommended projection
distance is 1069 mm and the vertical offset is 457.2 mm.
If your measured projection distance is 0.9 m (900 mm), the closest match in the "Distance
from Screen in mm" column is 884 mm. Looking across this row shows that a 100'' (about
2.5 m) screen is required.
MW851UST: For example, if you are using an 120-inch screen, the recommended
projection distance is 896 mm and the vertical offset is 355.4 mm.
If your measured projection distance is 0.9 m (900 mm), the closest match in the "Distance
from Screen in mm" column is 896 mm. Looking across this row shows that a 120'' (about
3.0 m) screen is required.
