This issue is common for vnc and sometimes other remote access software. The hardware workaround is to use dumb monitor plugs you can buy - fake monitor plug, that will add fake monitor via hdmi/display port plug. In past I wasn't able to overcome thing becuase its windows and gpu related issue - some gpus wont even post pc on restart/power on if you dont have monitor turn on. But I would gladly see this resolved here.

Please provide the name of said driver, I have tried many and none work.

I have been using these, which this video explains how to use.

close this since we have virtual display support now in 1.2.4.
