So, I don't use the PI variants with GUI or even with a monitor very often, but as I recall if the HDMI port isn't attached at boot it then disables it to save the video memory.

If you then try to use one of the VNC servers that's designed to share the running X session, you'll find that there isn't a running X session.

But what you should still be able to do is install the "vncserver" command to fire up an X server that isn't attached to the physical output, only the VNC.
|

You may need to configure it to also start your preferred display manager, etc depending on whether or not the distro you're running does that automatically for you.

If you want to be able to plug in a monitor later though you'll probably need one of the dummy plugs to prevent the output from being switched off and ignored.
