Mac Air M4/d6000 third display issues

[Peregood]

equipment:
- Macbook Air M4 running Tahoe 26.3 with displaylink drivers 15.1.
- Dell D6000 (natively supports 3 displays)
-1x 2K monitor and 2x 1080p monitors of the same model

When third display is plugged, one of the displays drops out.
Drivers were updated, reinstalled. Mac restarted, permissions given, FileVault dissabled.
Win machine does support the 3 monitor setup over the dock.

Any suggestions are welcome
