: Four times the native resolution of standard HD • Advanced color technology • State-of-the-art 3D
With the introduction of its new 2013 XBR sets, Sony has shown that it’s serious about bringing Ultra HD, popularly referred to as 4K, to consumers at prices that, while still high, are less seizure-inducing than the $25,000 sticker on its 84-inch XBR-84X900 (Home Theater, June 2013).
Technically, 4K is shorthand
for a resolution of 4096 x 2160 pixels—the professional 4K format. Consumer 4K sets, on the other hand, have a resolution of 3840 x 2160, exactly four times the pixel count of full HD 1080p. Regardless of the industry’s plan to refer to such sets as Ultra HD, 4K has already crept into the lexicon as the popular term for 3840 x 2160 home video.
