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).
