Even though CES 2014 is long gone, some of the stuff announced there is just now starting to become available for purchase. Case in point: Sharp’s Quattron+ lineup, a series of 2014 AQUOS televisions featuring the latest and greatest, including a revamped SmartCentral platform. But that’s not what’s interesting here. Instead, it’s the Quattron+ technology, one that Sharp describes as being able to “accept a 4K signal and play it back at near-4K resolution, with an effective resolution of 3840 x 2160.”
