Cablenet 20cm USB3.1c Male-DisplayPort Female 1.2 4Kx2K 60Hz Blk Active Adaptor

The current trend of making laptops thinner now means that many of the connectivity options you are used to seeing have been replaced by a single USB Type C socket.

Simply attach this unit to the USB Type C connector on the laptop and you will gain a DisplayPort socket.
You will then just need to connect to a display screen using the appropriate cable.
