Sony just announced a super slick projector called the 4K Ultra Short Throw Projector that'll be able to turn any wall into a 4K display. It's a part of Sony's new Life Space UX What's cool about the projector is that it's placed right next to a wall instead of behind your head. And that it uses lasers!
Sony's 4K projector was first announced last year, but they have the thing on display at CES this year. After getting to zone out in a pitch black room where the projector blasted the new Spider Man trailer at full resolution on a 182-inch screen, I'm sold on the idea.
JVC latest projectors—one at 8K (8,192x4,320pixels) and the other at 4K (3,840x2,160pixels)—come with 10,000 lumens of brightness and produce a 5500:1 contrast ratio.
