Hi, I have a Display Link USB 3.0 docking station - model UD-3900 that I cannot get the external display to show. I have a MacBook Air running OSX High Sierra 10.13.1 and have installed the latest DisplayLink driver.
The ethernet port is working - great. However, I cannot fathom the main functionality - extending the display. It does not show in the System Preferences / Display window
I have tried connecting my external display to the docking station using both DVI and HDMI - neither seems to work
Have I missed something basic here??
Appreciate any help you can provide
