And then I forgot the part for 2 months - it just totally harmless! (Audio I did not use).
Small Macke: In the accompanying description ... is HDMI to VGA ... that is wrong !!!
The little device converts from its input to its output HDMI VGA (label on the little device is correct!) So description better read only after you have connected the cables and everything works, so that the blood pressure does not rise unnecessarily ... !!!
