The popularity rating of projectors has seen tremendous increase in the
recent past owing to their varied uses and enormous advancement in

enjoyable home theatre experience or take it with you to a conference, a
projector can serve plenty of purposes.

set top box to watch movies or your favorite television programs on a
gigantic screen. It will really make the pictures come alive and leave you
craving for more.

audience in a meeting. The multimedia projector can be connected to a
laptop and used to display pictures, lectures or PowerPoint presentations

panels, which create bright and sharp images. LCD projectors are ideal for

Projector resolution: The number of pixels produced by a projector is known as its resolution.
The resolution is expressed in two numbers i.e. 800X600 or 1024X768, where
the first number is the horizontal pixel count while the second number
connotes vertical pixels. A higher pixel count means sharper picture.
Projector lumens: The brightness, which is measured in American National Standards Institute
or ANSI lumens, indicates how bright the projected images will be in a room
filled with light. The more the lumen count, the brighter will be the
images and the better you would be able to see it in a well lit room.
Projector contrast ratio: The projector contrast ratio indicates the difference between the darkest
and brightest areas of the picture. A projector with a higher contrast
ration will produce better shadow detail.
Projector weight: The projector weight, which generally ranges between 7 and 20 pounds,
assumes all the more significance if the projector is being used outside
home. Go for a lighter machine if you intend to move your projector from
one place to another frequently.
