For rich people with their own home theatre, this might be the answer to poor picture control from HD projectors. Saw an Oppo HD projector that sells for $48000 in New York and after the ahhs and aws had faded away and looked carefully, it was still not as good as a 60" Panasonic plasma display, which sells here for about R 55000.
The maximum resolution would be really a guide to its capabilities. I know of one person in Boston would be on the phone right away ordering one of these. I was in his theatre in Sep last year where he was showing me his top of the range Polaroid projector, but still thought that the contrast was not as good as many large TVs.
btw, the Polaroid used double HDMI connectors between the projector and amplifier. There was some BS explanation in the book about this, but the guys who set it up said that 2, 25 feet regular HDMI leads were cheaper than some super-duper HDMI cable costing hundreds of dollars that still not might transmit the correct signal. I once unplugged one of the HDMI cables and there was no visible difference.
