Dear DisplayLink macOS users,
We are aware that installing macOS version 10.13.4 will cause DisplayLink connected displays to go blank after the OS upgrade, with the latest DisplayLink driver release 4.1 installed. Extended displays continue to work as expected in macOS 10.13.3, and we recommend that you stay on macOS 10.13.3 or earlier if you require this feature, and have not already upgraded. Functionality such as Ethernet and audio, where implemented, is unaffected.
Our team has made some solid progress towards finding a solution which would restore extended display support for multiple DisplayLink displays, in a future release of macOS, but we are unable to provide a timeframe or a date for release of this solution at this time.
Meanwhile, we have an interim solution which enables one extended USB display (up to 1080p) on macOS 10.13.4, using AirPlay®. Additional DisplayLink screens will be in cloned mode. DisplayLink driver v4.3 beta 3 is available to download from our website today.
Please see the FAQ here on how to enable the DisplayLink AirPlay display for extend or mirror mode.
Thank you for your continued patience and we appreciate your feedback and support.
