The heart of these projectors'' advanced imaging technology lies in own three-LCD projection system. These three 0.7-inch LCDs are engineered and synchronized to achieve high levels of image quality, such as brightness distribution (illumination ratio), color saturation, color accuracy and efficiency. They create varying shades of red, green and blue that blend to produce a projected image with brighter, richer, truer colors and sharp black text. Barely two years ago, I hailed a projector that weighed in at under seven pounds. At the time, that seemed like a great breakthrough for weary road warriors. It meant that together with a laptop weighing six pounds or so, a mobile exec could have a complete presentation kit small enough to fit into an oversize briefcase and light enough to carry without risking grave damage to the back. Funny how these things evolve: By today''s standards, that setup is a big, bulky dinosaur. Your Application If you are giving a training presentation, you will probably need a brighter projector so the participants can read detail and take notes. A presentation using graphics and/or video will be visually less demanding and can be viewed in a darkened room. Your Screen Sufficient light reflection is provided in most screens on the market, thus making a low brightness projector look good in the right setting. The Number of People The image size increases as the number of people in the room increases. This reduces the brightness of the projector since the light is spread over a larger area. Another important thing to think about when buying a projector is the weight of the unit. If you travel quite a bit, you may want a very light weight unit. If you do not travel and want more features on the projector, you may opt for a heavier model. The Four weight classes of projector are as follows: Ultra-Mobile Ideal for the Traveling presenter. Typically weighing under 8 lbs, these machines provide a great low-weight-to-brightness ratio while maintaining the desired data resolution and video output. On the down side, some of the lightweight projectors sacrifice features such as power zoom, power focus, and remote control capabilities which can weigh the projector down. ©2003 www.overhead-projector.com All rights reserved. |
