Features to Consider When Choosing an Education Projector

Sony-auditorium-image-commercial-laser

When choosing a projector for your education applications, there are several factors to consider:

  • How Much Brightness Do You Need?
  • How Much Resolution Do You Need?
  • What Are Your Installation Requirements?
  • What Are the Best Presentation Tools for Your Applications?

How Much Brightness Do You Need?

The amount of brightness, or lumens, needed depends on your room conditions – whether or not there is some degree of control over ambient light.

General Brightness Scale:  Estimates for 100″ diag. screen

Room Environment Recommended Lumens
Bright w/ No Control Over Ambient Light 5000+
Bright w/ Some Control Over Ambient Light 3500-5000
Good Control Over Ambient Light 2000-3500
Able to Fully Darken 800-2000

How Much Resolution Do You Need?

Resolution is a term that refers to the number of horizontal and verticle pixels of the projected image. The higher the number of pixels, the higher the resolution, and the sharper the image.

Common resolutions found on education projectors:

Type Resolution Aspect Ratio
SVGA* 800 x 600 4:3
WVGA* 853 x 480 16:9
XGA 1024 x 768 4:3
WXGA 1280 x 800 16:10
WUXGA 1920 x 1200 16:10
1080p 1920 x 1080 16:9
4K UHD 3840 x 2160 16:9

* SVGA and WVGA are essentially “legacy” resolutions.

While there are still some very low cost projectors sold with SVGA an WVGA resolutions (including some “toy” priced dim LED pico projectors for home), but they are no longer normally bought by schools. There are still large numbers of them in K-12 schools. Most are long overdue for replacement. Their bulbs last only a fraction of the life of new projectors (nevermind laser projectors), so the cost of supporting those old projectors is high.

XGA models are typically used to replace the SVGA (and if any are still around – VGA) projectors. SVGA projectors are typically replaced by WXGA, WUXGA or 1080p projectors.

What Are the Best Presentation Tools for Your Applications?

Your applications, or specific uses for the projector, determine the presentation tools you will require in a projector.

The Field Museum makes extensive use of NEC projectors, using projection mapping, vertical operation, more. Here's a closer look at the vertical images.
