Latitude 5420 USB-C Stopped working with external display

The computer stopped sending a signal to it's external display through the USB-C ports today (was working yesterday).

Windows notifications pop-up to say the display is limited, and to check the drivers.

Troubleshooting so far:

  • updated all display drivers
  • uninstalled / re-installed all display drivers
  • tried a different monitor
  • tried different USB-C cables (3 different ones)
  • installed all of the Windows Updates

The USB-C ports on the laptop are still charging -- just not sending display out.

Any help / ideas appreciated!
