Cable serves as a connection between the PC and TV. If the cable is connected directly to the TV, it works without problems. However, it does not work with some HDMI switches. Have tested 3 switches. Only one was able to pass the signal to the TV. With my old 5m cables (5m + 5m extension) it had worked without problems. I think that the cable is different polarity. Sure, but I'm not there.
Nevertheless 5 stars because it works directly on the TV, and thus fulfills its purpose.
