A projector is an apparatus for presenting an enlarged image on a screen
from a transparency such as a photographic slide or a film. In a motion
picture projector, each frame is held stationary at an illuminated aperture
for a brief period, and then advanced by an intermittent sprocket or
reciprocating claw, the light being cut off by a rotating shutter during
the movement. One should have a clear idea about video projectors before
buying video projector screens.
Video projectors have become common and captured the market throughout the
world. They are especially common in schools and colleges where it becomes
necessary to show videos and films (especially in film schools and
institutes), or any place where people need to show films on a regular
basis at a cheap rate to a large number of people.
There is a wide range of video projector screens available in the market.
One can buy the kind of video projector screen one wants depending on the
kind of surface. The surfaces vary from smooth to rough, and minutely
undulated ones. However, before considering any video projector screens,
one should consider the following elements: resolution, brightness or
reflectivity, contrast, color accuracy, and build quality.
Some of the white (or gray) video projection screens can bring about a
difference in resolution, or image detail. There should be a rating to
indicate its inherent reflectivity, on which the brightness of the image
depends. Contrast of the image is also dependent to great extent on the
video projection screen. A screen should not reflect any color other than
that of the projector itself.
