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.
Projection dimensions
MX842UST
The screen aspect ratio is 4:3 and the projected picture is in a 4:3 aspect ratio
For example, if you are using an 120-inch screen, the recommended projection distance is
802 mm and the vertical offset is 485 mm.
If your measured projection distance is 0.7 m (700 mm), the closest match in the "(b)
Distance from screen" column is 708 mm. Looking across this row shows that a 110''
(about 2.8 m) screen is required.
