Thunderbolt adapter - LG monitor connection not working

I'm using this to connect a late 2013 iMac to an LG 27UK670-B and it's not working. Am I doing something wrong?

That display has a USB-C port but it's not Thunderbolt, so Thunderbolt adapters and cables won't work


Use a Mini DisplayPort to DisplayPort Cable from one of the iMac's Thunderbolt ports to the display's DisplayPort.
