Identify the connector used by your cable
To find the right solution for your Mac, use these images to identify the connector on the end of the cable used by your device. Check the end that plugs into your Mac, not the end that plugs into your device.
Thunderbolt 3 (USB-C)
If you're using an Apple Thunderbolt 3 (USB-C) cable or other Thunderbolt 3 (USB-C) cable with your display or other device, it should work with your Mac without an adapter.

Ethernet 
If you're using an Ethernet cable with your device, use a third-party USB-C to Ethernet adapter, such as the Belkin USB-C to Gigabit Ethernet Adapter.
DVI
