10.13.4 Displaylink no longer working

After upgrading to 10.13.4 my display link monitors no longer function. I've tried updating the displaylink drivers but this does not return the functionality to display multiple monitors that existed in 10.13.3. As a consequence I had to roll back to 10.13.3 to get my monitors to function again. This rollback also confirms that the issue appears to be in 10.13.4. I've got a very large number of MACs that I can not permit this upgrade to be deployed to in my enterprise as it will cause enormous support issues. Does some one have a fix as to how to get this minor bug fix update to function with displaylink?

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.3)

I have never used any DisplayLink equipment, but I read this thread after previously seeing complaints on other web sites and forums about DisplayLink breaking in 10.13.4. I just did a Google search and DisplayLink has a statement and beta drivers on their web site. They caution that their beta drivers are not a complete solution. Here is the link:

Important Information about macOS 10.13.4 update

We have become aware that installing macOS release Version 10.13.4 will cause DisplayLink connected displays to go blank after the OS upgrade, with the current DisplayLink driver [4.1] installed. Functionality such as Ethernet and audio, where implemented, is unaffected. We have alerted Apple to this issue and are working hard to find a resolution. These features continue to work as expected in 10.13.3.

In the meantime, we have a new driver [4.3] that will enable clone mode, but not mirror or extended mode displays in 10.13.4. If you require mirror or extended mode displays, we recommend that you stay on macOS 10.13.3 or earlier at this time.

Some are wondering if DisplayLink got broken as a result of the major video re-coding that Apple did to roll out final support for eGPUs in 10.13.4.
