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.

The distance from the projector to the screen determines the
actual size of the projected image, as shown:
7.5 ft
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 function to correct the distortion
caused by tilting up the front of the projector.
An ideal arrangement is to have the screen placed on the front
wall and allow as much space as possible between the screen and
the audience. This will let you move close to your audience and
still place the projector far enough from the screen to get a
good-sized image.
