can... this "dummy monitor" be used in windows by some other method? not exactly the same command obviously but a way to expose display on a headless system without using those dummy hdmi plugs?

Probably. That’s worth a shot. Any idea where the base64 stuff came from in the guide?

  That is the EDID data for the dummy monitor, it a small binary that contains resolutions and timings pulled from a real monitor.

  i mean windows is notorious for having a physical monitor attached. those dummy plugs help but not everyone has one...

I haven't yet found a production-ready open source virtual display driver for Windows, but there are a lot of "code samples" out there that work, you just need to go through the painful process of compiling and installing them. There's a big thread about this on the deskreen repo [0], maybe they've found something new since I last checked it. There is, however, a very good remote virtual monitor solution called Spacedesk [1], which has a windows server (with virtual display driver included) and a JavaScript client that runs in any browser (it refuses to run in Firefox, but if you just comment out that line of code it works perfectly fine).

You can write an IndirectDisplay class driver to expose virtual monitors

  how about this.... i am using RDP to connect to a windows machine. i have only 1 local monitor so technically i should only see 1 remote display but if i had a way to make dummy local monitors, that would signal rdp to "use all local monitors" and give me multiple remote displays.... same for remote viewers
