Positioning your projector Choosing a location Before choosing an installation location for your projector, take the following factors into consideration: • Size and position of your screen • Electrical outlet location • Location and distance between the projector and the rest of your equipment You can install your projector in the following ways. 1. Front 2. Rear Select this location with the projector placed on the table in front of the screen.
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.
For example, if you are using a 120-inch screen, the recommended projection distance in the "Average" column is 3436 mm. If your measured projection distance is 3700 mm, the closest match in the "Average" column is 3723 mm. Looking across this row shows that a 130'' (about 3.3 m) screen is required. To optimize your projection quality, we suggest to do the projection within non-gray area. All measurements are approximate and may vary from the actual sizes.
