D6000 stop working with MBA M1 2020 for several months.
 

I have been unable to use USB-C to detect video display from U2715 dell monitor. No matter what I do, I cannot get the monitor to detect on displaylink software. It won't wake up or get out of saving mode.

I have enabled displaylink in "screen recording" and "input monitoring".

Can anyone please help me please.

Are you connecting the Dell U2715 monitor via USB-C to the Dell D6000 docking station?

No, I'm connecting u2715 to d6000 dock via hdmi and then d6000's usb-c to the laptop.
