It certainly isn't small, but you shouldn't expect it to be if you're looking for every feature in the solar system for your ulta-cinematic experience projector.

The new Sony CineAlta 4K SRX-R220 can display 8,850,000 pixels of ultra high definition footage. This technological monster is the latest of Sony's SXRD (Silicon X-tal Reflective Display) line. Like the SRX-R1xx series it is yet to reach 10 megapixels, but it when it comes packed with many other features, there's less to worry about: LMT-100 media processor, LMS-100 screen management system, a gazillion gigabytes of RAID storage and uninterruptible power supply are all built-in.

The projector itself for any enthusiasts has 4096 x 2160 pixels resolution with a 2000:1 contrast and 14 foot Lambert brightness. The SRX-R220 model can fully cover a 20-metre screen (65.6 feet) with its 4.2W xenon lamp while the R110 goes up to 17 metres with a 3.0W and 14 meters with a 2.0W lamp.

Beyond connecting all kinds of video gear using BNC connectors you can also connect a computer, PlayStation 3 or AppleTV using a DVI port.

The SRX-R220 and SRX-R210 has prices starting at over $125,000, UK prices and availability to come.
