... With me it should be used only as WiDi adapter and since he has failed at least in my equipment. Neither my HP635 (AMD E450 CPU / GPU Radeon HD6320 / Windows 8.1) nor the BlackBerry Q10 wanted the stick by Miracast (at Grundig 55 VLE 922 BL) communicate. When BB came at least partly, still the message that I was the code which I displayed on the screen, should enter on the BB, but then the connection is lost, because of faulty negotiation. Trying using a USB extension to make the Stick "visible" also brought nothing. But use Pure-Fi worked without hesitation and without any problems. Etc. No disconnections in max cathedrals APP on the Grundig.
