Projectors

Multimedia projectors are electronic equipment that receive images or video data (whether from digital or analog sources) and project it through a screen using lenses and light. Today’s multimedia projectors can now adjust the image on the projection screen. This equipment has become popular for business uses such as meetings and conferences, public display, advertising and even in classrooms and at home theaters.

There are a variety of projectors that are made to suit the needs of a customer, through their light output that is measured in lumens. For example, projectors that have a light output up to 1500 lumens are suitable for small room conferences or classrooms. As the lumens increase, the more it becomes appropriate to larger projection screens, hence larger audience. 5100 lumens and up for example are best used on big expos and stage presentations.

Multimedia projectors have come a long way from the ancient times through pinhole cameras noted by Greek philosophers, to Leonardo da Vinci’s “magic lantern.” In the 18th and the 19th century, the early concept of projectors was used for creating illusions and entertainment. Eventually in the 20th century, the development of overhead projectors (and even the popular movie projectors) has led the way in the development of slide projectors. These projectors use analog sources such as negatives and films projected to a screen to be viewed. As technology progressed well into the 21st century, image or video sources have become digital, hence the development of multimedia projectors.

High speed processing and brilliant color technology combine to create only the best in multimedia projectors. PC Mall has a wide selection of multimedia projectors that are sure to bring ease to board meetings and office presentations. Reliable brands such as Infocus, Epson, Hitachi, Viewsonic and more produce bright images even under high ambient light environments with multimedia projectors that range from 1000 to 5100 lumens.
