4K x 2K projector that we've seen -- be it at CES, CEDIA or any other trade show -- has been solely for looks. Oh sure, they're for sale, but they're only being sold to cinema owners and the select few that find themselves within the same tax bracket as Bill Gates and Lawrence Ellison. But the DLA-RS4000... the DLA-RS4000 is different. Introduced here in Atlanta, the ultra high-definition projector spots a native resolution of 4,096 x 2,400, enabling it to display up to four screens of Full HD content (you listening, college football / NFL fans?) at once. Naturally, it's fully ISF and THX certified, and it packs 3,500 ANSI lumens, a Xenon lamp, 10,000:1 contrast ratio, RSVP4 video processing unit, Ethernet port and an RS-232c control port. Interested in showing 1080p what's really up? Great! Crack open that wallet and yank out $176,000 -- $175,000 for the beamer, and a grand to rent the forklift you'll need to get a 110 pound box into your home.
