Auditorium LCD Projectors are generally up to 40kg in weight, with 3,000 lumens (a measure of brightness) and above, have SVGA (brightness range from 1700 – 2000 lumens) or XGA (brightness range from 2000 – 3000 lumens, are more expensive than SVGA) native resolution. Auditorium projectors are mostly LCD projectors and usually come with a ceiling or rear mount facility. They usually have motorized zoom lens, are generally operated via remote control and offer multiple input and output ports for both PC and video. Auditorium LCD Projectors generally require external speakers and are targeted at spacious venues like theaters, auditoriums and convention halls.

Digital projectors are the modern replacements for the rather traditional transparency projectors. Transparency projectors worked by shining light through a semi-transparent material. Digital projectors, by contrast, project a digital image directly from a computer through a lens on to a screen.

The most important aspects of a home LCD projector are its feasibility and efficiency, combined with its usefulness. Compared to the CRT projectors, an LCD chip is amazingly small. An LCD projector is also a viable option in terms of power consumption, which is quite low.

As one student described it, stealing projectors was a dumb act of vandalism, and whoever did it took away from them their education. This was the remark of sophomore student, Matthew Kaulis in reaction to their campus’ stolen projectors. Stolen from their classrooms were seven Sharp projectors, with each costing $3,500 each. All have been replaced, though, according to the Media Center.

Using projectors can perhaps be a lot easier than understanding how the technology works. Projectors have been in use since 1420 (thanks to the idea of Johannes de Fontana) with the early projectors being just a lamp, some lens, and a white cloth for a screen. Although the principles applied to that projector is pretty much similar to what we have today, modern projectors have been developed to use some complex technology.

Presentations have never been more convincing and entertaining nowadays with the use of projectors. The use of projectors and accessories for power has replaced vintage type presentations that made use of the chalkboard/whiteboard and pens, and has minimized time consumption. We use projectors and accessories for power presentations, and not only that, various purposes and needs led to more advancement. Likewise, projectors and accessories for power enable presenters to make sure that they haven’t missed out on a topic/s because everything has been saved in the computer through certain software.
