Run deviceinstaller64 install usbmmIdd.inf usbmmidd (on 32-bit systems use deviceinstaller instead) as an Administrator to install the driver.Start command line in the directory you've just unpacked.Download and unpack somewhere, preferably without spaces or non-Latin characters.As far as I understand, it's a free part of a paid software named Amyuni USB Mobile Monitor (as in "free beer", but there may be other license restrictions). I found this forum post which provides a link to a pre-built driver which adds up to 4 virtual displays. Note that I am not looking for Virtual Desktop software, and I don't need anything as fancy as Matrox PowerDesk or Virtual Display Manager. VirtualMonitor which I think is almost what I want, but isn't compatible with Windows >7 and has some compatibility issues (?).DemoForge Mirage/ZoneScreen, which also require a connected client and are somewhat unstable on recent versions of Windows.SpaceDesk, which almost works except that my real display is bumped to #2, and requires a client to be connected.The "My display is not shown." option in the NVIDIA Control Panel, which won't let me add anything and only has options for televisions.Is there any way to force Windows 10 to think there's a display connected on VGA without extra hardware or paid software? I'm using a laptop with an NVIDIA 970M with HDMI, VGA, and DisplayPort out. The "Detect" button in Control Panel seems to do nothing, and the "Detect" button in Settings simply says a display was not connected. I just updated to Windows 10 and discovered that Microsoft broke this method of adding a fake second monitor: Is there a way to fake a dual (second) monitor which I rely on for scaling some small programs to full screen with OBS.
