LG's latest CineBeam ultra short-throw projector is a dream

Who wouldn't want a small box that can spit a 120-inch image onto your wall? That's the basic pitch behind 4K ultra short-throw (UST) projectors, which are sometimes called "Laser TVs." They're technically easier to set up than traditional projectors, and unlike large TVs, they don't require a huge footprint. Once you've placed it in front of a screen (or treated wall), you can summon an enormous cinematic image in an instant.
