At the device has now already everything written. Personally, I am very satisfied with the TV (especially for the price). Unfortunately, he can play on any USB 4K media (movies / photos) in 4K. For this you also need an additional 4K Media Player. I find anything in Orbsmart S82 (Android 4.4, Quad-Core / 2GB RAM), even the XBMC Media Center preinstalled.
