CES 2013: LG 55-inch 'ultra-HD' TV announced Monday

LAS VEGAS - LG unveiled a 55-inch TV that sports "ultrahigh-definition" resolution with more than 8 million pixels, kicking off what is likely to be a mini-obsession with the latest super-clear format at the annual International CES gadget show.

The model announced Monday is the smallest in a 2013 lineup that includes 65-inch and 84-inch versions. But the smaller size -- and likely smaller price tag -- begins the parade of TV makers that are seeking to bring ultrahigh definition to the masses.

Also known as "4K," ultrahigh-definition screens are 3,840 pixels wide and 2,160 pixels tall and have four times as many pixels as the current HD screens.

For a few years, there won't likely be a mainstream standard for getting native ultra-HD movies and TV shows to the screen either by disc or broadcast.

LG said these new TVs will have upscaling technology that takes images of lesser quality and renders them in high detail. The Korean electronics maker also said it has formed an ultra-HD content agreement with Korea's top broadcaster, KBS, and is seeking out deals with other global content providers. The company offered no specifics.

Along with the lineup of higher-resolution TVs, LG unveiled a new Magic Remote, which acts like a wand that is sensitive to motion and is used to navigate on-screen menus. LG said the new model responds better to natural speech.
