That VR desktop program "Virtual Desktop" has a funny requirement that you need the amount of physical monitors you want for the same multi-monitor setup in VR. You cannot just create virtual monitors that you don't have.

Is there any way to trick your computer into thinking you have more monitors than you do? I'm on Windows 10.
 
You used to be able to add additional VGA monitors by going into display properties and hitting a button that says something like "my monitor is not detected" Not sure if that still works.

There's also this dummy HDMI plug that I've seen mentioned before, seems to work well:
Headless Ghost - A simple HDMI plug display emulator
 
Anyone know why such circumvention is needed? Not being a developer I would think a virtual VR desktop program could just tell windows there's a huge new screen to work with
 
Video card drivers shut off outputs if they dont have anything connected im pretty sure. I used to put resistors into dvi adapters to trick the card into thinking it had a monitor connected. Could probably do the same thing with hdmi and display port adapters as well if you looked at the pinout
