Hello
I have a macbook pro M1 with Monterey that i want to connect to two displays:
- a Samsun display connected to the thunderbolt port
- An Old cinema display connected with a USB dock

If I connect only the usb display, The system uses the usb display without problems. SO cables are OK

IF I connect only the thunderbolt display there are no problems, the thunderbolt display works perfectly

If I connect both, the system uses the USB display and the thunderbolt display doesn't work

I installed Display link version 1.8.1
When connecting both thisplays as I said the system uses the USB display and Display link says "No display link-enabled display detected.

Anybody can help?
Thank you
