This is not supposed to be an issue! Sunshine works just fine on real screen!
There is a program called krfb-virtualmonitor. You can create a virtual monitor on a Wayland session.
However, it looks like sunshine can't detect this virtual monitor.
Sunshine detected:

Some PipeWire based screen capture program like obs-studio can see this display and capture them.

Did you get this from the terminal or from the troubleshooting tab? If you got it from anywhere else, it's just an example.

emm...
It is an example output...
The terminal output does have an Virtual-test monitor.
Then how can I use it?

I found I can use vkms kernel module to create a virtual display.(This module is marked as an EXPERMENTAL module and you have to compile it by yourself)
But I have yet another question: how can I bind ports using adb and let sunshine's network traffic goes through an USB cable (or wired adb debug) instead of my router?
I tried to bind only TCP ports in the configuration page (port 47986, 47987, 47981, 48007 and port 47986 is the family of ports used by Sunshine)
My router has a mesh setup and moonlight can't see my PC well.
