Are you usually on the road with only a bag or two in hand, or are you interested in creating a full-featured conference room? The size of a projector reflects your presentation plans. Projectors come in a variety of weights and sizes, so you need to be able to decide what's right for your specific needs:

How Do I Gauge A Projector's Brightness?
A projector's light output is measured in units called ANSI lumens. The more lumens, the brighter the image.
| Lumens Range |
Typical Application |
Room Lighting |
| Less than 1000 |
Small conference rooms and classrooms |
Dark or very dim |
| 1,000-2,000 |
Midsize conference rooms and classrooms |
Dim |
| 2,000-3,000 |
Large conference rooms and classrooms |
Dim or normal |
| More than 3,000 |
Large venues (boardrooms, auditoriums, theaters etc.) |

What Resolution Will Be Most Useful My Line Of Work?
Resolution refers to the level of detail your projector can display and is measured by pixels.
An example of resolution is 800 x 600. The first number (800) refers to the width of the image -- how many pixels are displayed horizontally. The second number (600) refers to the number of pixels displayed vertically, from top to bottom. More pixels mean higher resolution and clearer detail.

Note: For the best image, the resolution of the presenting laptop should match the resolution of the connected projector.
