Positioning your projector 16
Obtaining a preferred projected image size
Factors that affect the projected image size including the distance from the projector lens to the
screen, the zoom setting, and the video format. Tables of dimensions for both 16:9 and 4:3 screen
ratios are provided below to help you determining the ideal location for your projector.
1. Determine the aspect ratio of your screen (16:9 or 4:3).
2. Select your desired Screen Size from the applicable screen dimension table below (16:9 or 4:3
ratio, depending on your screen ratio). Install the projector at a distance from the screen
between the Min. and Max. Projection Distance values in the table.
3. Determine the preferred height of your projector.
For example, if you have a 16:9 screen that is 69.7 in. W x 39.4 in. H (177 cm W x 100 cm H), you
should place your projector within a range of 92.1 in. to 125.2 in. (234 cm to 318 cm) from the screen.
The ideal height of your projector lens center will be level with the bottom or top side of the
screen.
