The cable is well made and makes a really high-quality impression. I wanted to connect it to my MacBook Pro Retina used the end of 2013 to an external monitor. Unfortunately, no signal was transmitted. A defective cable is ruled out, because I have tried it with another without success. The HDMI port on the MacBook also has had no defect. I then me a much cheaper cable with mini DP - buy> DP. Thus, the transmission worked without problems.
