Hello,

I have an issue with the external display using the Lenovo USB-C dock 40AY which said it's displaylink compatible.

When connected, it recognize only 1 external screen - but I have 2 connected. The same image is mirror on both screen.

DisplayLink is well installed but on the monitor page it says "please connect your display link devices"

Any idea ?
