Dear DisplayLink macOS users,
Installing macOS 10.13.4 will cause DisplayLink connected displays to go blank after the OS update when using DisplayLink driver v4.1. Extended displays continue to work as expected in macOS 10.13.3, and we can only recommend that you stay on macOS 10.13.3 or earlier if you require this feature and have not already updated. Functionality such as Ethernet and audio, where implemented, is unaffected.
We have now released DisplayLink driver v4.3 beta 4 providing an interim solution with one extended USB display (720p or 1080p) on macOS 10.13.4, using Apple AirPlay®. All additional DisplayLink screens will be cloning the primary display. This updated beta removes two main restrictions from last week's v4.3 beta 3: Wi-Fi no longer needs to be enabled, and the driver is allowed access through the system firewall. When starting the machine, AirPlay requires you to re-plug the device after login.
Please see the updated FAQ for details on how to enable the DisplayLink AirPlay display for extend or mirror mode.
Our team has made some solid progress towards finding a solution which would restore full extended display support for multiple DisplayLink displays in a future release of macOS, but we are unable to provide a time-frame or a date for release of this solution at this time. We will provide an update on this thread as soon as we are able.
Thank you for your continued patience and we appreciate your feedback and support.
Kind regards,
Alban
