usb – Is is possible to make a raspberry pi be recognized as a monitor by the computer, and receive its video output?

Context

I would like to build a e-paper computer screen. The problem is that E-paper displays have a very different driving method from usual displays, as they usually have low refresh rate (something around 1s for the fastest) and support partial refresh.

So for that project, I need to take the video flux of my computer, analyze it, and then drive the monitor accordingly. I see two options for now :

  • Tinker with X11 or another display server on the main computer, which seems very complicated.
  • Have a raspberry pi or other SoC act as a monitor, and drive the display from there, which is especially convenient given it would be seamless for the main computer.

The question

Is there a way to have the raspberry pi be recognized as a monitor by a computer, ideally through USB, and receive and process the video output from the computer ?

Maybe there are other ways, like a hat ?
