Two monitors - only one extended display

[rdobbe]

Dear all,

For my MacBook Pro (13-inch, M1, 2020), I use a Dell docking station Dell K20A001 and have connected two Dell monitors:
- U2417H
- P2319H
Both are connected to the docking station via a 20 pin DisplayPort cable.

On my MacBook, I have the DisplayLink Manager 1.8 installed.

The problem: I get only one extended screen, which is mirrored across the two Dell monitors.

I would like to have two extended screens, one for each monitor.

Is this possible? And if so, how do I fix it?

Thank you very much in advance for your advice.

Kind greetings,
Roel
