The Dell WD19, WD15, WD19TB, and D6000 docking stations reportedly have issues detecting external monitors connected through HDMI or USB-C.
Here’s the quick fix recommended by Dell Support:
- Disconnect the docking station from both the laptop and the monitor.
- Wait for 1 minute, and then reconnect the docking station back to both the laptop and monitor.
In 99% of cases, this will resolve the problem.
Your monitor and docking station might be working fine, and the issue could be due to loose cables.
Make sure that the display cables, such as HDMI and your monitor power cable are properly secured. Switch the ends of the HDMI cable.
If the HDMI or USB-C cable, whichever you are using for data connection, is damaged, your laptop won’t be able to send information to the monitor.
If your laptop comes with multiple USB Type-C ports, connect the dock to different port on the laptop and try again.
Most monitors come with multiple input ports, so ensure that correct port selected as the input source in the monitor’s settings.

- Right-click on your display driver and choose Update Driver.
- Select Search automatically for the driver option.
