A video projector is a device that projects a video or computer image onto
a screen. The commonly used inputs are video cassette players, CD and DVD
players and PowerPoint presentations from computers. Some computers have CD
as well as DVD drives which support these discs. Some projectors don’t have
VGA connectors, which take inputs from a computer.
A video projector employs one of three technologies: CRT, LCD and DLP. CRT
projectors are just like television, i.e. they employ cathode ray tubes.
The limitations of CRT video projectors are the heavy size and the
requirement of absolute darkness for clarity of the picture. LCD projectors
employ a special chip so that the advantage is that the projector is very
compact. Besides, it has excellent contrast and brightness. The LCD
projector employs individual pixels, which produces high resolution. The
limitation of a LCD is it produces a screen door effect. Also the repair of
one would result in a dark spot on the screen.
DLP technology employs a Digital Micromirror Device, instead of a chip. DLP
projectors are highly suitable for viewing movies and also other multimedia
presentations. The advantages of DLP projector include color accuracy and
no screen door effect.
LCD and DLP video projectors are the favorites and therefore most of the
inventory of the rental companies are the above mentioned ones. The rates
of these projectors start at $100 and are dependent upon factors such as
the resolution and weight. The rental companies provide support throughout
the whole day and night. This includes online or phone booking, shipment,
installation, and operation support.
Hotels, resorts, convention centers and conference halls enter into
contract with rental companies to provide these services. The rental
companies have chains of shops across a particular region or nationwide
networks. The directories of these service providers can be obtained
online, which directs them to the individual websites.
