Front Screen Installations 
While there are two basic screen types, flat and curved, generally flat screens are 
recommended for this projector (Figure 2.17). Flat screens offer a gain of about 1 
with a viewing angle just less than 180°. Incident light reflects equally in all 
directions so the audience can see the display from various angles. Because of the 
low gain, flat screens are most effective when ambient lighting is reduced,...

Ideally, to fill a screen with an image, the aspect ratio of the screen should be equal to 
the aspect ratio of the image. The aspect ratio of an image is expressed as the ratio of 
its width to its height such as a 4:3 aspect. Standard video from a VCR has a 4:3 
aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10-
foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m). 
Aspect ratio...
