Portable Projectors Guide

Using portable projectors for your presentations with your bullet points written large on the wall for all to see is far more effective than using a notebook. The trick is to find a portable projector that's powerful enough to be useful, but small enough to cart with you. Five pounds is the maximum weight if you want to avoid using a wheeled case.

Brightness and contrast ratio are key features. You can't conduct meetings in the dark, so a projector must be bright enough to cast an image on a wall in a partially lit environment. Similarly, a bright unit can project a big image suitable for presenting to large groups. Contrast ratio improves readability in well-lit rooms and provides richer blacks when displaying video. If you look for a brightness of approximately 1500 lumens and a contrast ratio of about 700:1 or more, you won't be disappointed with your portable projectors performance.

Resolution and zoom controls are also important. A low-end projector may have only an 800 x 600-pixel resolution. That's fine for PowerPoint presentations, but to present spreadsheets effectively you'll want 1,024 x 768 pixels. And zoom controls let you project a large image on a wall without having to put the projector across the room.
