   We are 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 are releasing 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 at this time.

   We understand that this loss of functionality on OS upgrade is potentially disruptive for our users and customers. Please be assured that this issue has the highest business priority in DisplayLink. We thank you for your patience and will provide an update on this situation, as soon as we have further information to share.

   I also noticed that the kernel extension has a team ID of "3YQY62QM3" - which is nine characters. Every other KEXT in my list has a 10 character team ID.

   I'm wondering if this is an error in a programmer's cut and paste?

   It may be causing a problem in 10.13.4 as the kernel signing system is tighter.

   This indeed correct. It breaks when you upgrade from 10.13.3 and an uninstall and install of the latest drivers makes no difference.
