For years now TV manufacturers have been scrambling to find a feature that’ll get you to buy new TV. They tried 3-D, which crashed and burned. No one fell for smart TV “features” either, which were typically wrapped in a UI that made you want to smash your remote. Now 4K (Ultra HD or UHD) is coming. And while those extra pixels will be wasted on the average household, if Dolby’s research into a brighter screen technology is adopted by manufacturers, those UltraHD TVs will actually deliver a substantially better picture to everyone.
