Plugable UD-3900c4 is not showing 4 screens

My Docking Station is only showing 2 screens.

I am using:
Lenovo Yoga 7i Connected with the provided USB-c cord.
HP 32s connected to the Docking Station with HDMI cords.
What am I dong wrong?

Hi Matthew,

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

Looking at the specifications for that laptop, it looks like it should have two Thunderbolt 4 ports, which should be fully supported by this docking station.

We are still awaiting more information about your system from the other ticket that was open for this issue. I will be happy to update this post with any information based on based on the log files we requested.

Thank you.
