note It is easier to position the projector when the screen is directly in front of the room. If the screen is placed diagonally in a corner, it is much more difficult to position the projector perpendicular to the screen and get a non-distorted image. Most presenters find it convenient to place the projector (and computer) in the front of the room. With this arrangement, the projector is placed close to the screen. You need to raise the front of the projector (by extending the legs) in order to position the image high enough on the screen. Then you can use the projector's keystone control to correct the distortion caused by tilting up the front of the projector. The distance between the projector and the screen determines the actual image size. Use the general guidelines in the table below to determine the proper distance. Horizontal distance from projector to screen Image size (diagonal) Minimum (lens set to W) Maximum (lens set to T) 2.2 feet (0.7 meter) - 3.6 feet (1.1 meters) 2.5 feet (0.8 meter) 3.6 feet (1.1 meters) 4.3 feet (1.3 meter) 3.3 feet (1.0 meter) 4.8 feet (1.5 meters) 5.6 feet (1.7 meters) 5.0 feet (1.5 meters) 7.5 feet (2.3 meters) 8.9 feet (2.7 meters) 6.7 feet (2.0 meters) 9.8 feet (3.0 meters) 11.8 feet (3.6 meters) 8.3 feet (2.5 meters) 12.5 feet (3.8 meters) 14.8 feet (4.5 meters) 12.5 feet (3.8 meters) 18.7 feet (5.7 meters) 22.6 feet (6.9 meters) 16.7 feet (5.1 meters) 25.3 feet (7.7 meters) 30.2 feet (9.2 meters) 25 feet (7.6 meters) 37.7 feet (11.5 meters) 45.3 feet (13.8 meters) 6 Connecting to a Desktop Computer
