By updates you mean updates of the DisplayLink driver or updates of MacOS? Either way hopefully it will get fixed soon!

Sorry for the delay, in case you still need it, my Mac information is as follows:

MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports)
2.3 GHz Intel Core i5
16 GB 2133 MHz LPDDR3
Intel Iris Plus Graphics 655 1536 MB

Even with the latest beta 2 it's still not working :(

Last week I got already in contact with displaylink support.
My system:
MacBook Pro 13 (2018)
i7, 16 GB RAM

Correct, beta 2 didn't fix the problem..... I think we need an update of the DisplayLink drivers.

2 weeks without external monitor on my dock :mad:

@DisplayLink: any solution from your site?

uff... ;)

With the latest 10.14.4 public beta 3 it's working again.
Finally!

I'll try and get that installed tomorrow!

Seems to broken in 10.14.4 beta 4
 

I updated to Driver 5.1 with Mac OS 10.14.4 this week and it appears to be broken again! Displays are both blank but show up in the Display selection on the Mac.

same here
 

Same issue with MacOS 10.14.4 Beta (18E205e) and DisplayLink 5.1 driver installed. The driver is properly loaded. The display is NOT detected in Displays settings at all.

Found out the root cause: my USB port connected to DisplayLink VGA adapter wasn't detected at all. I changed the USB port to another USB hub and it started working again. So not an issue with the driver after all.
