I bought the adapter at random, in the hope that it also with my current PC graphics card (AMD 280X R9 of VTX3D) works. First, the Enttäuschnung because when connected to my TV set appeared the message that no audio signal is transmitted with could be. How can the address I asked myself? The answer was relatively easy because I use an additional HDMI switch and there is obviously the tone "lost". With a direct connection via HDMI cable to the TV everything works properly in Full-HD with sound! Buy recommendation.
