Mega Sale - Projectors

Projectors typically have many input signal options, featuring composite, S-Video, VGA or HDMI. You can project on plain white walls, but to get the best performance, choose from the range of professional projection screens available. Depending on the way in which they process the internal video signal, projectors are either LCD or DLP. Although these technologies are different, and LCD projectors used to be considered better for projecting data from computers while DLP models were ideal for screening films, today both technologies are practically equivalent.

LCD Projectors
The light source in LCD projectors passes through three primary colour filters. Each then passes into one of three LCD panels through a permeable layer. Finally, all three colours are combined again and projected through an optical device onto a screen, where they are displayed as a complete picture. These devices are both lightweight and easy to maintain.

DLP Projectors
DLP projectors work with DMD chips and use a large number of microscopic mirrors, with each mirror representing one pixel. The image is again broken down into the three primary colours (red, blue, green) and then passes through the micro mirrors and lens before being projected onto a screen.
