The consumer-electronics industry thinks it knows what will persuade you to replace your high-definition TV: even more resolution. The emerging standard for next generation video, 4K TV, packs four times as many pixels as today's highest-resolution sets. Also known as Ultra HD, the technology powers fantastically crisp, vivid new televisions at sizes of up to no in. Spectacular though it is, 4K may be years away from real-world living rooms. Right now, it's available only on a few giant TVs at giant prices: Samsung is taking preorders, in South Korea only, for an 85 in. set priced at $38,000. LG, Panasonic, Samsung, Sony and Toshiba are ramping up their 4K lineups.
