As 4K technology slowly starts entering the mainstream content providers are moving to make access to content in Ultra High Definition more easy. Online video streaming sites like Netflix and Amazon have already started streaming content in 4K. Now a major pay-TV provider, Comcast, is getting in the game as well. Today the launch of Comcast’s Xfinity in UHD app took place. It is an on-demand programming application, and there’s just one thing wrong with it, the app is only available for 2014 Samsung UHD TVs. So if you own a 4K television but its from a manufacturer other than Samsung, even if the model is from 2014, you’re out of luck.
