Got a spare $12,000? You can experience LG's flavor of the future of television when its 55-inch OLED model hits the U.S. in March. Just 4mm thick, sets promise ultra-crisp and -bright pictures with staggeringly high contrast levels that existing models can't match. Think characters that better pop from backgrounds and black levels that reach shades so deep they appear bottomless. Big spenders be warned, though: That five-figure tag? Just a starting price.
