Cablenet 20cm USB 3.1c Male - HDMI 1.4b Female (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The current trend of making laptops thinner now means that many of the connectivity options you are used to seeing have been replaced by a single USB Type C socket.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 an HDMI socket.
You will then just need to connect to a display screen using the appropriate cable.
