Hello,
Thank you for getting in touch with us on this case.
There should be no issue with a MacBook Pro (2019) to work correctly with DisplayLink.
I would recommend to download our new beta version app that supports macOS 10.15 Catalina
Here is the link:

If you will face any issues after installing the driver feel free to contact us again either on forum or by following the last link in my signature.
Best regards,
Jakub
