Position the Projector
1. Position the projector at an
appropriate throw distance
(projector-to-screen
distance) and vertical
position. Ideally, center the
projector with the screen.
If space is limited, aim the
projector slightly off-
center as shown in Figure
2-2. This increases side
keystoning, but reduces
the horizontal lens offset
required.
2. Attach the supplied safety strap to the back of the projector and fasten it to its mounting surface. Use of the
strap is mandatory to prevent the projector from tipping when a lens or auxiliary lens mount is installed.
NOTE: keep the projector lens surface as parallel to the screen as possible, even if significantly above the
screen center. When a particularly short throw distance combines with a very wide screen, you may have to
forfeit some aim and stay more parallel to the screen. In such cases, some lens offset can reduce the keystone
distortion.
