I was assembling a dock for my MacBook Pro laptop at work. The dock has a mini DisplayPort output that I connect to an inexpensive Samsung 4K monitor. I first used an HDMI cable connected to a Mini DisplayPort to HDMI2 adapter. The results were a mess to work with. The picture was generally good, but the text rendering was terrible. He drove me crazy when I had to write something. I read that a DisplayPort connection solves this problem. This cable did it. The text rendering is perfect and the picture looks great. This cable is highly recommended if you need a Mini DisplayPort to DisplayPort connection.
