Positioning the projector
To determine where to position the projector, consider the size and shape of your screen, the location of your power outlets, and the distance between the projector and the rest of your equipment. Here are some general guide- lines:
• Position the projector on a flat surface at a right angle to the screen. The |
projector must be at least 4.9 feet (1.5m) from the projection screen. |
• Position the projector within 10 feet (3m) of your power source and |
within 6 feet (1.8m) of your video device (unless you purchase exten- |
sion cables). To ensure adequate cable access, do not place the projector |
within 6 inches (.15m) of a wall or other object. |
• If you are installing the projector on the ceiling, refer to the installation |
guide that comes with the Ceiling Mount Kit for more information. To |
turn the image upside down, see “Ceiling” on page 31. We recommend |
using an InFocus authorized ceiling mount. |

• Position the projector the desired distance from the screen. The distance |
from the lens of the projector to the screen, the zoom setting, and the |
video format determine the size of the projected image. |
• The image exits the projector at a given angle. This image offset is |
112.2%. This means that if you have an image 10’ high, the bottom of |
the image will be 1.12’ above the center of the lens. |
