When it arrives later this year, LG's 84LM9600 will be the first TV in the U.S. with a native resolution of 3,840x2,160 pixels -- four times that of current 1080p TVs.
Unlike OLED, another new display technology shown off at CES this year, 4K TVs are actually on the market. There's just one catch.
Along with 4K resolution of 8.3 million pixels per frame, the sets boast 4.1-channel surround system and support for the company's Magic Remote, which lets you control the TV by speaking.
The company says the television comes with more than 8 million pixels, quadrupling the resolution in full HD displays.
The prototype, which is being showcased at the Ceatec technology fair, can zoom in to 4x and maintain full-HD resolution.
The Consumer Electronics Association has announced that the consumer name for 4K will be Ultra HD and gears up for displays to be shown off at next year's CES in Las Vegas.
Believe it or not, there are already more than 20 models of flat-panel LED LCD TVs with 4K resolution for sale in the US. Their prices are still high, but falling very fast. Here's how they stack up in mid-November.
Reinforcing the coming-out party 4K resolution TVs threw at CES 2013, NPD DisplaySearch predicts 2.6 million panels with ship in 2013, up from 63 thousand last year.
Joining Samsung and Sony in the nacent 4K TV price war, LG debuts its least-expensive versions yet. Like those of LG's compeditors, these TV start at $3500.
Samsung, Sony, and LG have all announced insanely expensive 4K TVs in "smaller" 55- and 65-inch sizes, but only LG's tout full-array local dimming, which may allow its TVs to outperform the others.
