Several models are designed for portability and are especially useful when making business or academic presentations at other places. Just connect your notebook or desktop computer to the projector's audio and video ports and project a multimedia experience for all to share. Overview Multimedia Projectors may also offer viability for the visually challenged. The large image, as presented on the wall or screen, can help make characters and images easier to recognize. There may be models that can't display at all these resolutions.
Higher resolutions become important when displaying more sophisticated graphics and animations.
Another crucial factor to image presentation is brightness. Like all projectors, an electric bulb acts as a light source and a brighter bulb provides a brighter image. Each multimedia projector uses a very special bulb, usually designed specifically for the brand or model. If you go to the supermarket and purchase light bulbs for your home, you may notice that there's a 'lumens' rating on the package. The more lumens available, the brighter the projection is.
