Hello,

I would like to apologize for the delay in getting back to you.

As your dock works fine in USB-A mode, I don't see the issue is with DisplayLink chip, driver or firmware.
The HDMI output can be driven from 2 different modes: DisplayLink over standard USB, or DisplayPort Alternate-Mode over USB-C plug.
The internal circuitry of the Dell D6000 means that for DisplayLink, everything is DisplayPort (Dell has DisplayPort to HDMI converter to drive the HDMI output from either DisplayLink or DisplayPort over USB-C).
From a driver point of view, having a DisplayPort or HDMI is not different.
I think the dock USB-C controller is playing up here. It doesn't activate in USB-A mode, and you seem to have full functionality in USB-A mode.

Would you please be able to use the Dell flasher to update the controller they have in the dock?

If you've got access to C:\Windows\Temp\DisplayLink, I could also have a look at DisplayLinkManager.log, to be taken just after you've reproduced the problem and then disconnected the dock (so the file isn't open).

Kind regards,
Alban
