Projection Screens There is one large projection surface. The screen measures approximately 8 feet across and 6 feet tall.
The
diagonal image size that is projected by the Data projector measures
about10
feet. The screen is lowered either manually by pulling on a cord or electrically using a rocker switch on the wall. Some classrooms provide a second, smaller projection screen for use with an overhead or a 35mm Slide projector (as shown on right).
