I’m experiencing issues with my Plugable UD-6950H Docking Station not working with external monitors despite following all setup steps and troubleshooting

Hi everyone,

I am experiencing an issue with my Plugable UD-6950H Docking Station and wanted to share a summary of my troubleshooting process here while I await a response from the support team.


Order Information

  • Product: Plugable Universal Laptop Docking Station, 4K Dual Monitor

System Information

  • Operating System: macOS 14.7.1 (23H222)
  • Setup Completed:
    • Installed and verified DisplayLink Manager for macOS is running.
    • Granted necessary Screen Recording permissions in macOS ‘Privacy & Security’ settings.
    • Enabled USB accessories permission for Apple Silicon Macs.

Issue Details

The docking station is not functioning with external monitors, despite completing all required setup steps and extensive troubleshooting.

  1. Cables Used:
  • UANTIN USB C to HDMI Cable
  • Warrky USB C to DisplayPort Cable
  • uni USB C to DisplayPort Cable
  • uni USB C to HDMI Cable
  1. Monitors Tested:
  • Primary Monitor: MNN Portable Monitor 15.6" FHD 1080P
  • Secondary Monitor: Lenovo ThinkVision M14 Monitor
  1. Ports and combinations tested: Multiple ports with each cable across two different monitors.

Troubleshooting Steps Taken

  1. Fully reset both the docking station and my computer.
  2. Used PlugDebug to generate two log files:
  • One after the initial setup.
  • One after resetting everything.
  1. Verified all permissions were granted, and DisplayLink Manager was actively running.

Current Status

The docking station is under warranty, as it was purchased last week. I’ve emailed Plugable support with the above details and attached the PlugDebug log files for review.

I’ve also requested a phone call for quicker troubleshooting if possible. If anyone has encountered similar issues or has additional insights, I’d appreciate your input while waiting for further guidance from support.

Thanks!

I’ve been assigned Request #452900 with the ticket assigned to Michael S.

Hello!

Thank you for posting this discussion. Thank you also for reaching out through our support channel. I wanted to post our findings here so that folks who find this thread may benefit from our discussion in the support ticket.

The issue here is that both the MNN Portable Monitor and Lenovo ThinkVision M14 Monitor support a USB-C video port (DisplayLink Alt Mode), and, unfortunately, a USB-C video interface would not work with the UD-6950H.

In order for both monitors to work, they would need to support either a direct HDMI or mini HDMI video input. Since both monitors support USB-C DisplayPort Alt Mode video inputs, using an HDMI to USB-C cable would be incompatible. The connect must be HDMI direct to HDMI.

If anyone has any questions regarding this case, please feel free to reach out to us directly through our support channel at support@plugable.com

Best,

Michael S.
