Go to best buy; I just did. When you see the ultraflix logos on every single new 4k TV in there, you'll realize that they are riding Sony's coattails in a brilliant move! The guy working there said that 4k is going to be pushed in a big way in the fall "August timeframe" with studios set to push out more and more movies on 4k blurays. Either I just haven't been paying attention or this is the next bigthing in entertainment. 3d and curved TVs are gimmicky, 4k is impressive. NTEK just needs to crank out more content! I downloaded the app for my tablet which can do up to 2k and it worked and looked great it just needs more CONTENT!
