Choosing a location
Your room layout or personal preference will dictate which installation location you

*There are two menu types for your selection. One...

Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and 
the video format each factors in the projected image size.
The projector should always be placed horizontally level (like flat on a table), and 
positioned directly perpendicular (90° right-angle square) to the horizontal center of 
the screen. This prevents image distortion caused by angled projections (or projecting 
onto angled surfaces)....

Projection dimensions
Refer to Dimensions on page 71 for the center of lens dimensions of this projector 
before calculating the appropriate position.
For example, If you are using a 60-inch screen, the projection distance is 2194 mm and 
with a vertical offset of 120 mm.
If your measured projection distance is 5.5 m (5500 mm), the closest match in the 
Distance from screen (mm) column is 5485 mm. Looking across this row shows that a 
150 (about 3810 mm) screen is required....
