I recently had an issue to use my working HP 840 G11 notebook and my personal Macbnook Pro M1 for dual screen monitors instead of always re-connect one of my monitors to a display-port -> USB-C adaptor and connect both monitors to my M1.

Before.
Step1. Remove one display port monitor, connect an adaptor from display port to USB-C and connecto one USB of M1.
Step2. Connect the docking directly to M1 to another USB-C port of M1. Had dual monitors connected.

When I had to use my working notebook, I had to undo everything and so on.

Now I had for a test a HP Thunderbolt G4 Dock and I found a post here to ajust dual screen monitors for both M1 and HP 840 G11 that i’m using for work. It looks like is working perfectly well. The only problem I have now is that the new docking doesn’t have an audio out. One workaround is to use an external usb-c sound card.
