Display 1 not working on UD-ULTC4K

I have a MacBook Pro with an M3 chip running 14.1.1.

Display 1 is attached via an HDMI cable
Display 2 is attached via an HDMI cable
Display link manager is installed and running

When I open Displays in my settings it shows that the laptop is recognizing the two extended displays. I can even move things into Display 1, but it is a black screen. Nothing showing. What do I need to do to fix this?

Thank you

Hi Craig,

Thanks for reaching out to Plugable support! I’d be happy to help with that.

There are a few things that we want to clarify because this type of docking station uses two distinctively different types of display technologies.

First, we’ll want to make sure that we understand which display you are having issue with as labeled on the back of the docking station. Specifically, are you having an issue with a display connected to display connection 1, 2, or 3 as labeled on the back of the docking station.

Additionally, it would be very helpful to know the exact make and model of the display that you are having issue connecting.

Thank you for providing us this helpful information.
