Choosing the Right Projector

Today, a projector is an imperative tool in multimedia presentations. They are used by teachers to aid in lessons, corporations during training seminars, in houses of worship and countless other arenas. Choosing the right data or digital projector is important in making multimedia work for you.

There are three popular projector types LCD on silicon, LCD, or DLP.

LCD projectors use liquid crystal glass displays and color panels to project an image onto a screen. These devices have good color saturation and often used for displaying PC images. They typically use less energy.

DLP is digital light processing technology. This process involves the manipulation of light through thousands of tiny mirrors. DLP tends to be more popular with home cinema and movies.

LCD on silicon (Lcos) have higher saturation and better performance then an LCD, but typically costs significantly more.

Where Will It Be Used?

The first question you have to ask is where you wish to use your projector. A projector is an ideal presentation tool for the following locations:

  • Auditoriums
  • Classroom
  • Courtrooms
  • Places of worship

In addition, ask yourself:

  • Does it need to be portable?
  • Can it be stationary?

Major Considerations

Lumens:
A lumen is a measure of light. The more lumens the brighter the projector. High lumens allow you to overcome ambient light and project images at longer distances. A projector that is used in a small, dark room would not be suitable in a large, well-lit auditorium.

Resolution:
There are two levels of resolution available on most data projectors SVGA and XGA. XGA is higher and shows greater detail than SVGA . For basic PowerPoint and text projections, SVGA is suitable; however, for movies, image-intensive PowerPoint presentation, interactive websites or Excel spreadsheets, XGA is recommended.

Size and Portability:
When choosing the right data projector, one question you need to ask is what size you need and will it be stationary or portable. Some portable data projectors typically have a footprint around the size of a sheet of notebook paper and weigh as little as 4 pounds.

Connections: Make sure that the projector you choose will allow you to connect to the media you wish to use.

  • Some projectors offer multiple VGA connections, which allow you to project your computer’s image while still using your local monitor. This feature is called a monitor loop through.
  • If you wish to use a remote diagnostic monitoring system to track usage, temperature read-outs and more, you should look for a network connection (RJ-45).
  • With the increase in emphasis on high definition, an increasing number of projections are now coming with digital video connections allowing even more options of inputs.
