I have tried every troubleshooting tip I can find with no luck. I had a MacBook Air M1 with a GIQ docking station running the same macOS with two HP monitors that worked with no issue. Please help.

If you have not done so already, I would suggest contacting Plugable directly for assistance --> https://plugable.com/pages/support
