Mobile Generally a step up from the Ultra-Mobile class in brightness and features, these projectors are designed for presenters on the move. This class is great for small-to-medium sized presentation environments. These units are typically 8 to 13 lbs. Conference The Conference class projector is designed for either permanent or portable applications. Work station connectivity and control system interface is available for most of these projectors. The typical weight is 13 to 30 lbs. Projectors are designed for the professional environment. Applications would include large classrooms, conference/training facilities, engineering and design, and religious venues. The typical weight for these projectors is over 30 lbs. Under $3,000.00 In this price range, you find mostly SVGA projectors that offer under 500 lumens of brightness and may or may not include zoom lenses and other accessories such as cables, cases and remote controls. These machines usually make great projectors for small training or classrooms where control of light is offered. $3,000.00 to $5,000.00 A step up in class, these projectors are typically SVGA ranging from 550 to 800 lumens.

Picking the right resolution Here are some basic guidelines for choosing the right resolution: Pick a resolution that is adequate for your presentation. If you use mostly type presentations, you can save money by going with a lower (SVGA) resolution. If you are, however, presenting information with a lot of numeric data, you may want an XGA resolution. And for highly detailed and technical presentations, such as engineering drawings, you may need the higher resolution SXGA projector. Get a projector that matches the native resolution of your computer. If you have a computer with SVGA resolution, then an SVGA projector will give the sharpest and cleanest image. Most of the projectors today can project input signals other than their native resolution, however, there may be a loss of sharpness and detail in the process. If you have a high resolution computer and a matching resolution projector is out of your price range, choose a projector that is one step down in resolution. Projectors convert a different input format to its native output format through a process called "scaling". Some projector are very good at scaling, thus making the fuzziness in the image very minor. The quality of scaling varies among different projectors.

we''ve created even greater values for customers in the projector marketplace." 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.
