They look good, but most top-of-the-line HDTVs still sound like the TVs we grew up with. Even with huge displays, many TVs lack solid speakers and rely on separate systems to match the 2 million pixels that you're seeing on a standard HD screen.

The 65-inch Sony X900B Ultra HD TV solves that problem with a design tweak — a slight wedge shape means there's room for larger speakers and built-in subwoofers, creating a louder sound and deeper bass. Beyond sound, the X900B looks incredible thanks to Sony's hardworking tech that makes it easier to see every color. And, oh yeah, it's got a ridiculously detailed 4K screen, too. If you were counting, that's 8 million pixels.
