I have an application I have written for a customer, they want to be able to show the application via a vnc connection instead of a monitor, the reason for this is, the monitor connection will be used to display some digital signage.
so what I am looking for ( I think ) is something similar to what you can do in Linux, which creates a virtual desktop, and displays that via the VNC connection, and just runs it in memory.
This is all done on a Windows 10 system, and is on a small format board, similar to a Pi.
I have searched all over, I found one program, but it just didn't seem to work, I had to run it in XP compatibility mode !!
any advice would be much appreciated
You can install an X-server on Windows Subsystem for Linux.
This one is the first I found with google: https://x410.dev
PS there are also other X-server for Windows, you just need to search for them.
