This is really great. It’s an entirely self-contained home theater solution. The DV10, from company Optoma, integrates a DVD player, a set of speakers (two 5-watt stereo) and a projector. All you have to do is show up at a friend’s house with this, place it 5ft away from a white wall, pop in a DVD and you’ll be able to enjoy a 50inch screen, right then and there. It’s even HDTV compatible!
Of course, you can use it like a standard projector as well. It comes with a bunch of I/O connections (Composite (RCA), D-sub 15 VGA(analog RGB/component/HDTV), S-Video, RS-232 communication, Stereo audio in, Stereo audio out, Optical audio out), so you can play games, connect your satellite, hook up your real sound system, etc.
It features brightness of 1,000 lumens, a contrast ratio of 4,000:1 and a bulb life of 2,000 hours. So, as a regular projector, it does well enough also.
The price for all this wonder? $1500.
