Hello

I have a MBP 15" 2017 connected to a Plugable USBC-4K DOCK (model UD-ULTC4K). The dock has two DisplayPorts and one HDMI input. The dock is connected to the MBP with the supplied USB-C cable. Connected to the dock are three 2K ViewSonic 27" screens, all arranged in portrait format.

All 3 monitors fire up when the Macbook starts. However, only the HDMI screen is able to be arranged in portrait formation using the 'Rotation' drop-down menu under system preferences-->Displays menu. The other two DisplayPort screens remain landscaped - there is no drop down menu available.

The dock/MBP is running the latest DisplayLink drivers release date 26/05/2020.

Does anyone have any ideas how i can rotate these displays into portrait formation please? As I unable to use them for any sort of work at the moment.

Thanks
