The cable here is a usb-c cable for mini display port, usb-c is also called usb 3.1 or usb type c and mini display port is called mini dp. 

The cable is black and 1.8m long. It supports up to 4k at 60hz if the monitor you have supports this resolution. It also clears 1080p, 1440p, 2560x1440,1900x1200 both at 60hz but also at multiple hz, e.g. 1080p at 140hz. The standard is display port 1.2. 

The cable is good if, for example, you have a Dell display with mini display port or any other monitor that uses the mini display port to connect to your mac. 

The cable is made for the new Macs with usb-c and Thunderbolt 3, the cable works for any mac that has either usb-c or Thunderbolt 3. These are the new Macbook pro's, MacBooks and iMacs. 

The cable is built well and comes from a company that makes no other one usb-c cables and mini display port cables, that's why they can fix it at this low price. 

The cable has two he connectors, usb type c at one end and mini display port at the other end. 

The chips sit in the mini display port end that's why this is where cables are thickest, it makes the part to be sitting in your screen all the time is the part that is greatest and the part that you take in and out of your mac is the smallest. 

The cable works both ways, but it doesn't have as many features if you use the mini display port end of your PC or video device, only the video part works and you need to be sure that the monitor or projector sends the signal right for it to work, therefore the cable is made to a usb-c device and a mini display port display.
