Cablenet 20cm USB 3.1c Male-DisplayPort Female 1.2 4Kx2K30Hz Tailed Blk Active

The current trend of making laptops thinner now means that many of the connectivity options you are used to seeing have been replaced by a single USB Type C socket.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