Multimedia Projector Overview

Projector Categories
The main categories of projectors currently available are......
    
Things to consider when purchasing a Multimedia Projector include computer compatibility (most work with current PC and Macintosh systems), brightness of image, resolution capabilities, and portability.
Resolution
Multimedia Projectors, like computer monitors, are capable of presenting images in a number of different resolution settings, including VGA (640x480), SVGA (800x600), XGA (1024x768) and SXGA (1200x1024). As the resolution level increases, so does the level of detail which can be shown and a sharper, clearer image is displayed. It is important to choose a projector which is compatible with the resolution of the source which is to be used.
Brightness - Lumens
Another crucial factor to image presentation is brightness. Like all projectors, an electric bulb acts as a light source and a brighter bulb provides a brighter image. Each multimedia projector uses a very special bulb, usually designed specifically for the brand or model. Brightness is measured in Lumens, following standards defined by the American National Standards Institute (ANSI). The more lumens available, the brighter the projection is.
