Latitude 5420, USB Type-C dock, secondary display not working
I have found a problem with the new Dell Display adaptor driver for the Five Guys Dell Latitude 5420's. It does not work with the Dell USBC docking station. The second display will not initialise properly and the display flashes on and off. There is a continuous connecting and disconnecting windows sound as if the system is constantly trying to initialise the display. The driver is a new driver released on the 20th April 2021. To fix the problem you need to revert to the old December 2020 driver. This works fine, you will need to keep an eye out for this as users can accidentally install the driver if the use the Dell Command Update Application for windows 10.

The problem is now resolved as I reverted back to the December 2020 driver.

I have the same issue with the USB-C. When I plug in the power the port works. But the secondary display is not working through the port. I have been using this port for a secondary display before, it suddenly stopped working. I checked that the problem is not with the monitor, the cable, and the adapter. The problem should be with the port.
