Macbook Air M3 only - Displaylink only recognizes Display in the HDMI1 Altmode port

I'm having the same trouble. I have two HP 527sf monitors and can only get one of them to work in the first instance.

I can get both to work by toggling on and off HDMI2 on DisplayLink Manager - but this only causes both external monitors to show the same thing (basically a duplicate of HDMI1) - and only the one monitor is recognised on the Displays window of system settings.

I have now tried it with another monitor on HDMI2 (HP Pavilion 23xi) and that works in extended mode and is recognised by the computer (MacBook Air M1).

Could it be something to do with both monitors having exactly the same name? Or is this a 527/monitor specific issue (and if so, why would that be?).
