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.
Image sizing
The RETRO BLOCK REALITY 909 + standard HFQ900 lens is designed for projecting an image width from 1400 mm (55.1 inch) to
6000 mm (236.2 inch).
The lens type can be found on the lens label located on the lenshead (image 3.1).
The projector leaves the BARCO factory, adjusted as a Front/Table projector for a screen width of 2400 mm (94.5 inch), with
an aspect ratio of 4 to 3 (image 3.2).
The projector can be factory aligned in other configurations if ordered.
Changing the image size from the factory preset size requires a realignment of the projector.
