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,…

Request ETA as to when an updated driver will be available to correct this problem.

After four days following Apple's release of OS X v10.13.4, aside from the obligatory but otherwise useless "We're aware of the problem..." post from "Product Manager Wim" on 3/30, not one single status report pertaining to the resolution of the driver issue has been forthcoming. At this point, I'm seriously questioning whether anyone in DisplayLink tech support is monitoring this thread. I've lost several hours in productivity over the past two days because of this issue and, from the number of other complaints on this thread, I seem to have quite a bit of company. If you have an ETA for releasing a driver patch, please share that information with us. If you don't, then kindly tell us so that we can evaluate alternative solutions. I look forward to the courtesy of an immediate reply. Thank you.
