"What we considered portable projectors 15 years ago weighed 20 lbs.," said Richard McPherson, NEC senior product manager for projectors. "Now, portable can be an 8-lb. projector or much less." You can still buy an overhead projector but it probably makes more sense to take advantage of the latest advances, especially if you want a crowded auditorium to see what you are presenting. "You need a larger screen too because you need to spread that information out so that everybody can see it," said McPherson, "Today's projectors are made to accommodate a large screen." Portable projectors can fit into a shirt pocket or be large enough that it is probably better if it is permanently installed. They can, among other things, connect to wireless networks or project data and images from smart phones and tablets. Low-cost operation and maintenance have become key features and important selling points. "Computers, and the need for different resolutions as-well-as more complicated content, have driven much of the advancements in features found in today's projectors," said McPherson, "The more content the greater the need for higher resolution." BRIGHTNESS AND RESOLUTION Casio XJ-H2650 McPherson advises that clients base their buying decisions on a projector's brightness, resolution and versatility. This includes the ability to change projector lenses as necessary. Also, buyers should determine how the projector will most frequently be used in order to match features with the desired price point. Other potential features include edge-blending and stacking capabilities. Edge-blending allows the use of multiple projectors to produce a massive image on a screen without discernible lines between video segments. Stacking uses multiple projectors with software that overlaps single images and increases brightness at a cost that can be less than buying a single projector with higher light output. "Depending the situation, they may need three projectors one day and only need one the next," said McPherson Projectors used in small, well-lit venues can use projectors with moderate brightness. Larger rooms need even greater light output. BLOGS A little more on photos More about photos What is "The News"?
