Sequoia 15.4 Beta on MBP missing 1 monitor

[EMBkk]

This is still a problem. Why is this being ignored? Anyone from DisplayLink who can comment on this?

I've cleaned up the Displaylink installation and re-installed the latest driver 1.11 but that didn't help. When I connect that blank (no signal) HDMI monitor directly to the MBP M4 Pro HDMI it works fine and I can see all 3 monitors as I had before I installed 15.4 Beta with 2 via the dock and the 3rd directly to the MBP. But this is not ideal.

Has anyone encountered this and was able to solve it?

Thank you.
