Projectors - What 4 Things To Look For Before Buying One.

Projectors - What 4 Things To Look For Before Buying One.
Of the many pieces of technology that exist to make today's
office more effective and efficient, perhaps none is more
important than a digital projector. A digital projector
represents a solid investment that every business, big or
small, should consider making.

Today's fast-changing technology makes it important for
consumers to consider several factors when purchasing a
digital projector in order to ensure that they receive
maximum returns on their investment, as well as to avoid
being stuck with a piece of technology that will be useless
and obsolete in a matter of months.

As far as price is concerned, when it comes to technology,
you do often get what you pay for. Though it isn't
necessary to spend several thousand dollars on a projector,
businesses need to consider the amount and type of use they
expect from their projector and make their decision
accordingly.

Besides price, the other important factors to consider when
investing in a projector are brightness, resolution,
contrast, and lamp life.

Typically, the level of brightness in today's projectors
ranges from 1000 to as high as 10,000 lumens. When
selecting a projector, consider where it will be used. If
the projector is meant for use in a small, dark room and
for a small audience, less lumens (1000-1500) will usually
suffice. However, a projector that will be used in a
larger, brighter area such as a hall or auditorium will
require more lumens (2000-3000).

Choosing the resolution for your projector is based mainly
on the type of presentations it will be used for.
Resolution is divided into four categories, including SVGA,
XGA, SXGA, and UXGA. SVGA represents the most affordable
option, and is the resolution typically needed for
projecting simple graphics, as in those found in Power
Point presentations. XGA is a resolution typically used to
project video images, as well as small-type spreadsheets.
SXGA is also known as high resolution, as is intended for
use with presentations that require presentation of very
small details, as in some CAD applications. UXGA
represents the highest resolution, and in intended to
presentations of applications that are high in both detail
and information.

Contrast refers to the difference between the light and
dark colors of a projected image. When choosing a
projector, choose one with a high contrast ratio, typically
400:1 or higher. If a projector is meant for use in a room
with high levels of light (or even with the lights on),
choose one with the highest possible contrast ratio.

The life of a projector lamp typically ranges from 40-80
hours on the lower-end lamps, to as high as 4,000-4,500
hours for the more expensive xenon lamps. On average,
today's projector lamps usually last about 1,000 hours.
When making a purchase, take into consideration the amount
of use you expect to get from your projector, and the fact
that replacement lamps typically cost $200-$500.
