Why am I writing here:
first ran namely me nothing or almost nothing to the part and I the same scrap, scrap roared .. ;-)
For "lucky" I had another adapter which also did not work, so I was forced to my Samsung doubting PC monitor and rouse me to test the cable to other devices. Behold on a Samsung TV and a Dell PC monitor everything went wonderfully.
Ergo the slightly older Samsung PC monitor (24 inch) probably provides enough power or the wrong power so anyway because, after all, rarely came but just an image or Gekrissel. The power for the electronics in the adapter must obviously come from the TV because the TV is already connected noticed something when the adapter otherwise (Micro-USB and USB) still do nirgens drinsteckt.
The Samsung PC monitor, however, noticed that if at all, then only in brief lucid moments.
This is not a criticism of the Delock adapter but at the SlimPort operation: the power supply for the electronics in the adapter should take place not only via HDMI but also via USB.
So scolds not equal to the adapter if it was not doing people but even then checks it to other equipment, if none at hand at grandma, aunt or neighbor. Good luck and all good things come from above ...
