I recently saw an infomercial on the shopathometv.com channel for a Benq projector with DLP technology. They say that it has composite, s-video, progressive scan component video and SVGA input. The native resolution says it is 800x600, but they say it supports both 720p and 1080i HDTV resolutions. Is this true or BS? At $1500 for the DLP projector and an 84inch screen it seems to good to be true.
