Create a virtual display on GeForce boards


My goal is to create a virtual display on a GeForce 1080.

I was wondering if there is any alternative for the NvAPI_GPU_SetEdid method on GeForce board? Indeed, according to the documentation this feature is not supported on GeForce, QUADRO VX, and Tesla boards.

I tried to play with the value EdidLockData of the registry key Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm\State\DisplayDatabase and I managed to have a virtual display but its removal does not work every time. I am not sure this is the right way to do it. Futhermore, I do not fully understand how this registry value works. Is this documented somewhere?

Thanks in advance.
