Windows 10: Miracast bug/problem

Hello. I've bought new TV, LG 55 UM7450 and i want to stream to it from my pc wirelessly. This is where my problems start.

When i checked if my device supports miracast on Dxdiag, it says it does, but i dont have "add wireless display" option anywhere, and when i open Win+S - Connect , it ways this device doesnt support miracast. Also when i go to devices, add device, wireless display or dock, it just searches for device for ages. On tv i set it to share screen- miracast. As the connection goes, i tried to miracast over LAN ( which should be possible since Win 1703) to a dead end, then i found i have TL-WN722N wireless usb adapter, but still didnt find a soulution. Basicly my pc doesnt recognise it can miracast, while DXDiag does. Any advice or help apriciated. Also any questions or additional info will be provided.
