Positioning your projector Choosing a location Your projector is designed to be installed in one of four possible installation locations: 1. Front Table Select this location with the projector placed near the floor in front of the screen. This is the most common way to position the projector for quick setup and portability. 3. Rear Ceiling Select this location with the projector suspended upside-down from the ceiling behind the screen.
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. 4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9 (widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the projector's native aspect width. This will result in a proportionally smaller height equivalent to 75% of the projector's native aspect height.
3. On that same row, look across to the right column and make note of the "Vertical offset (mm)" value. This will determine the final vertical offset placement of the projector in relation to the edge of the screen. 4. The recommended position for the projector is aligned perpendicular to the horizontal center of the screen, at the distance from the screen determined in step 2 above, and offset by the value determined in step 3 above.
