It really does sound like quite a bang for the buck in the realm of classroom projectors.

Mitsubishi recently announced its contribution to the classroom projector release season with the wide-screen WXGA WD570U. Widescreen is important for a lot of new classroom applications and hi def video. Since the projector has LAN display, four computers can be connected to the device at the same time to divide the screen into fourths in support of a move toward more collaborative learning in the classroom. With its 3500 lumen output and 3000:1 contrast ratio, I don’t see this projector being limited to the classroom—it should find solid footing in the business market as well. We look forward to receiving a product sample and reviewing this projector in the coming weeks.
