UD-6950PDZ with '21 MacBook Pro M1 Pro

I am using the UD-6950PDZ with my 16" '21 MacBook Pro and 3 monitors, a 32" 4k, and 2 1080 24" monitors. I’ve had no trouble until two weeks ago. Now, everything connected to the dock loses connections, all 3 screens go black, then it re-connects automatically. This happens so often, that I am no longer able to use the dock and connected monitors because I lose audio, then have to restart all safari windows. After about 4 or 5 crashes, the monitors won’t restart and I have to shut down my MacBook and reboot it. I am using DisplayLink Manager 1.8.0

I have disconnected one of the 24" monitors to see if that helps, but it doesn’t behave any differently with only 2 monitors connected.

Is this a known issue with Macs?

Hi Tom,

Thank you for contacting us, I am sorry this is not working as expected and I am happy to help!

Based on your description I would like to start by fully resetting the docking station and computer to see if this helps to restore the functionality, please try the following:

  1. Disconnect the docking station from the computer and remove the power connection from the back of the docking station, unplug all USB devices from the docking station
  2. Disconnect the docking station’s power supply from the wall and let both the docking station and power supply sit for 30-90 seconds to fully discharge
  3. Restart the computer
  4. In macOS: Apple Menu > Restart
  5. After 30-90 seconds, reconnect the power supply to the wall socket or power strip
  6. Reconnect the power supply to the docking station
  7. Verify the blue power LED is illuminated on the front of the docking station, please let me know if this does not come on when connected
  8. Reconnect the docking station to the computer
  9. Please be sure to use the original USB cable provided with the docking station
  10. Connect the cable directly from the docking station to the computer, adapters, hubs, or cable extensions may reduce the docking station’s capabilities or prevent detection
  11. Check for the external displays to be detected on the system, if they are not detected please let me know
  12. Reconnect USB devices to the docking station one at a time, test each device to make sure it is working before connecting the next device.

Additionally, if you have any USB devices connected for charging, like a phone or tablet please leave these disconnected for now to see if this helps with reliability.

Please let me know if this helps, if not we can go from here.
