Hi-Res on Screen

Small notebooks and netbooks that can put high resolution images and video are an excellent way to put them on the big screen in front of the class. The problem is that often the projector can’t keep up. That’s not the case with Mitsubishi’s FD630U projector, which combines full 1080p output with an astoundingly bright 4,000 lumens of light. Based on Texas Instruments’ latest digital light processing imaging engine, the FD630U has a 10 watt amplifier and the ability for the teacher to plug a microphone in, creating a classroom public address system. For those who worry about maintenance costs, the projectors don’t need an air filter and its lamp can run for as much as 5,000 hours without being changed. With a 3-year warranty (1 year on the lamp), the FD630U sells for $3,500.
