Choosing the Right Projector
Several factors should be considered when choosing the right projector for your needs.
The most important are Brightness, Resolution, Contrast Ratio and Weight.
We have provided a general explanation of these key elements.
1. Brightness: Measured in lumens, the higher the lumens,
the brighter the projected image. The more light you have in a room when using the projector,
the more lumens you'll need. A dark room requires less lumens from a projector.
Most projectors project at least 1000 to 1200 lumens. This is usually adequate for dark rooms.
However, if you expect light (perhaps notes need to be taken or blinds cannot be closed all the way),
consider a projector that provides greater than 1200 lumens. Most professional presenters tend to stay along the
lines of 1800 lumens and greater. You should also realize that larger images need more lumens to project clear images.
If brightness is the most important feature that you desire, consider the following:
Epson Powerlite 8300i - 5200 Lumens
Infocus LP850 - 4500 Lumens
NEC MT1065 - 3200 Lumens
2. Resolution: This is similar to resolutions offered by computer monitors.
The greater the resolution, the more information you can display on a screen. 800 x 600 is usually sufficient for standard
presentations that do not require a great deal of detail. However, if you require detail or plan to project images and animations
(such as marketing professionals), consider a resolution above 800 x 600. Projectors today typically offer SVGA, XGA and SXGA resolutions.
SVGA is usually sufficient for simple presentations. However, for more advanced presentations or larger projected image needs, consider
going with at least XGA. For extreme detail, go with SXGA.
3. Contrast ratio: This is a measure of a projectors blackest black and it's whitest white.
It basically equates to the brightness of the projector over any room light. There is much debate today over how much the contrast
ratio actually affects projected image detail. Some say that anything over 400:1 is pretty irrelevant. However, a good rule of thumb
is that if you plan on doing standard, still image presentations without too much detail, then anything over 300:1 really won't make a
difference in the overall scheme of things. But if you plan on presenting video presentations with great detail, consider going with a
projector that offers a greater contrast ratio. At this time, there is no industry standard of measuring contrast ratio. So a manufacturer
that claims a 400:1 contrast ratio may project nicer than another manufacturer claiming the same contrast ratio, given that all other specs
are equal.
If contrast ratio is the most important feature that you desire, consider the following:
Infocus X1 - 2000:1 Contrast Ratio
BenQ PB2120 - 2000:1 Contrast Ratio
Mitsubishi XD70U - 2000:1 Contrast Ratio
4. Weight: When purchasing a projector, make sure and choose one that is weighted according to your needs.
If you plan on traveling a lot with the unit, choose a lighter projector and consider purchasing a hard roller case for protection
and ease of transport.
If you plan on traveling with this projector, consider the following:
Infocus LP120 - 1.98 lbs
Infocus LP70 - 2.4 lbs
Epson Powerlite 730C - 4.3 lbs
Other key factors are price and added features such as aspect ratios and wireless capability. If your key usage is home theater, make sure the projector can support a 16:9 aspect ratio so that you can get experience the wide-screen capability of most DVD's. If you plan on using your projector in a room where you want the least amount of "clutter" running from the PC to the projector, consider a wireless capable model. These are just a few of the "extra" features to consider. However, the above listed key elements are generally the most important.
