Sony 4K Home Theater Projector

If you thought the “4K” in Sony’s 4K Home Theater Projector ($2,5000) means it costs around $4,000, you’re far off. The 4K stands for the next generation video-standard with a 4096 x 2160 image resolution soon to be available on air. That’s 4x larger than standard HD.  Along with the insane image detail, the 4K features a SXRD panel and a lamp bright enough to project on screens of sizes up to 200 inches, a 2.1 motorized zoom, expanded throw distances, an RS232 interface, control over IP and, of course, an upscaler for 1080p video.
