You've finally picked up a monster-sized high-definition 1080p flatscreen for your entertainment center, you're plowing through your Blu-ray stacks of Lost or Friday Night Lights or Breaking Bad at a crisp, eyeball-thrilling 1920 x 1080 pixels, and then you see this: Sony's launching a projector that'll run at 4K, or 4096 x 2160 pixels.
Wait, what? 4096 wide by 2160 high? Isn't that some kind of digital cinema format? Why yes, yes it is. In fact it's the high-end of digital cinema formats. Most use 2K, or 2048 x 1080 pixels, only a tick better than your increasingly standard home theater's 1080p, so 4K's pretty much cutting edge. Films shot in 4K are fairly recent, too—think District 9, Knowing and The Social Network.
Meet Sony's VPL-VW1000ES 4K, but don't worry, you probably can't afford one. Sony says it'll ship this December for just shy of $25,000 (including installation). But oh what you'd enjoy if you had that sort of disposable income: a home theater front projector capable of displaying four times the resolution of HDTV.
