Those two ports are toggled and share resources, so only one can be active for video at a time. Choose either HDMI 2.0 or the rear USB-C DP Alt Mode based on your display setup.
Is this answer helpful?
Disconnect the dock’s AC adapter, wait a few seconds, reconnect power, then reattach the host. The dock requires AC to renegotiate power and re-establish the EC-to-EC connection.
Is this answer helpful?
Yes. Certain WD19 variants support the WD22TB4 cable module. Update firmware before and after the swap and ensure a 180W adapter is used to enable full functionality.
Is this answer helpful?
