Displaylink is not supported (M1 and Dell display)

[RolledSleeves]

I am using a similar set up with the same results:
Displaylink compatible Plugable, UD-3900H
OS: mac 12.0.1

I have recently been using the 1.5 release, with my Dell display (S2721Q) as well. It has worked fine, but when updating to the 1.6 version for the rotated screen, my Dell monitor does not get an image, but my LG monitory is able to see the display as well as rotate.

I have switched HDMI cables and ports to my plugable dock, but each time only my Dell monitor is left black.

If you download Version 1.5 it should work (you just will not get screen rotation)

Hopefully there is a patch soon for the Dell monitors.
