The latest in a line of widescreen DLP projectors to be released by Mitsubishi is the HD4000U which just began to ship a few weeks ago. This WXGA resolution unit (1280x768, 15:9 aspect ratio), is rated at 2000 ANSI lumens of brightness and 2500:1 contrast. So it is both brighter and lower in contrast than most new widescreen models intended for home theater. The reason is that the HD4000U is targeted toward system integrators and commercial multipurpose data/video application use. It is an ideal data projection system to be matched with a widescreen laptop computer, especially for users who are interested in portability and low cost. Mitsubishi does not market this product as a home theater projector, and that is as it should be. Though it certainly can fill in well for part time home use, it would not be our first choice for use as a dedicated home theater projector.
