INSTALLATION GUIDELINES
* Which screen type?
There are two major categories of screens used for projection equipment. Those used
for front projected images and those for rear projection applications.
Screens are rated by how much light they reflect (or transmit in the case of rear
projection systems) given a determined amount of light projected toward them. The
'GAIN' of a screen is the term used. Front and rear screens are both rated in terms
of gain. The gain of screens range from a white matte screen with a gain of 1 (x1) to
a brushed aluminized screen with a gain of 10 (x10) or more. The choice between
higher and lower gain screens is largely a matter of personal preference and another
consideration called the Viewing angle.
In considering the type of screen to choose, determine where the viewers will be
located and go for the highest gain screen possible. A high gain screen will provide
a brighter picture but reduce the viewing angle.
For more information about screens, contact your local screen supplier.
* What image size? How big should the image be?
The BARCOVISION 701 MULTIMEDIA is designed for projecting an image width
from 1.4m (4.6') to 7m (23') with an aspect ratio of 4 to 3. It leaves the BARCO
factory, adjusted as a ceiling front projector for a screen width of 2.4m. Changing
the image size from the factory preset requires a realignment of the projector.
