Move over 4K TVs, there's a new kid on the block. Well, half a kid really.

Combining high resolution and high dynamic range promises to deliver not just pixel perfect images but color perfect ones too. And Sony's new batch of Android TV powered BRAVIA TVs, led by the XD93, are more than ready to start that revolution.
