Presentation Skills: Using Your Projection Screen

When using projection of any kind, try to avoid rooms with low ceilings and/or
It won't make much difference for small audiences, but for large
ones it is quite important. If the screen is too low, it makes it virtually
impossible for those in the back to see and, of course, a low hanging chandelier
will obstruct the audience's view.

If you have a choice, ask for a matte finish screen. It gives the greatest
horizontal viewing angle so people looking at the screen at an angle will be able
to see the image more clearly. All screens must be tilted forward at the top or
backward at the bottom to eliminate the keystone effect (top of image is wider
than bottom). Many portable screens have a keystone eliminator at the top, or
you can simply use masking tape on the lens of the projector to square off the

Most of the time you will try to place the screen at an angle in the front
corner of the room.
This way the screen is not directly behind
you competing for the audience's attention. The lights right above the screen
should be turned off so the image doesn't get washed out.
