system sleep in display-closed mode does not work

[Gjonjordan23]

Hi
I have a MacBook Air M1 2020 and a Dell D3100 docking station, which was the one that worked to connect with 2 monitors through display link. thanks DL for this feature it is very helpful and prevented me from throwing my monitors out of the window.

The only problem i still struggle with is that the system sleep in display closed mode does not work. I turn it off and close my macbook but my 2 monitors shut down as well and i would love to only use 2 monitors and prevent my macbook air to be on in a weird, place consuming position.

Does anyone have the same struggles and tries to find out how to solve it?

PS: i recently downloaded the graphics connectivity and also the support tool for macbook but nothing seems to work even after shutting down my computer.

Thanks for any advice!
