External Display not working after Sonoma Update

I have a Portable Tri-Screen for Laptop which has been working perfectly up until Sonoma Update. I have tried all methods of attaching the screens according to the instructions with no results.

The Tri-Screen works on a Windows laptop.

MacBook Air 13″, macOS 14.0

You might need to update your displays firmware. See the site of your display manufacturer for instructions
