Buying DLP Projectors and LCD Projectors

Many of us have closets full of slides. We may even have an old
slide-projector in there also. The desire to share our memories with others
and to see them life-size has made our lives better. We like to see
ourselves as we were when we were in various stages of growing up. We love
to look at pictures of our grown-up children when they were small.
PowerPoint has long ago replaced the slides and the projector that now sits
unused has been replaced by video projectors. So it’s definitely time to
move on as more people are purchasing home theater projectors for the 21st
century.

So how big do I need? How much must I pay to get good resolution? These are
good questions to ask before you make this investment. This article will
help you understand what’s behind some of the choices you’ll make.

First of all, there are two types of high-definition projectors. You won’t
go wrong if you purchase either type; even so, you need to understand the
difference before purchasing any of the home theater projectors on the
market today.

DLP Projectors

Digital Light Processing uses tiny mirrors, each of which projects a pixel
similar to a very tiny laser beam. This process makes the image from the
projector highly precise and sharply defined. If you want to leave your
projector running for a long time, a DLP projector will not lose color and
picture quality.

LCD Projectors

In an LCD projector, a small, very clear liquid crystal display panel
receives the light rays in either red, green, or blue. A prism lined with
these LCDs, which direct the light to the screen, result in a
vibrantly-colored, very precise image with high definition. If an LCD
projector runs for more than ten hours, the picture will begin to lose
quality.

ANSI Lumens

If you’re using the projector in the same room all the time, you’ll
determine how many ANSI (American National Standards Institute) lumens you
need by how much ambient light is in the room. If you’re going to use it in
a variety of settings such as a speaker sometimes does, carrying the
projector to various sites, that will be a determining factor.

The size of your screen also makes a difference in how many ANSI lumens you
need in your projector. An image from a projector with 2000 ANSI lumens
will look washed out on a 100-inch screen, but it will be quite sharp on a
small screen. If you have ambient lighting in your room or if you’re using
it in a variety of settings, 1400 ANSI lumens or more are generally
recommended.

Contrast Ratio

The higher the contrast ratio, the blacker the blacks and the whiter the
whites. This, of course, affects color definition. With 1000:1 contrast
ratio, the whitest white is 1000 times whiter than the blackest black. A
rule of thumb is that 4000:1 is good for any setting although adjustment of
contrast is more flexible with a higher ratio, for example 10,000:1.

Conclusion

This information along with taking into account where your projector will
be used, should prepare you to shop and look for home theater projectors
with confidence.
