Hi all, I have a problem So when there is no monitor connected to the client computer the multiplicty window appears black. When I connect a monitor then everything works fine. I use Multiplicity KVM not seamless. I have a small rendering farm with 8 clean install machines with 3ds max only. and windows firewall, windows 10 pro 64 (1803) - I reinstalled Multiplicity, i ran the bat file and updated the video card drivers. All the slave machines have one screen plugged in from a physical KVM. If there is no monitor plugged in multiplicity displays a black screen. If i turn the monitor on with my real world KVM then Multiplicity works. This in my point of view points to some windows or display driver changes from the last update ...
I used multiplicity for 3 years in the exact same machines every day. I came back from holiday and after a few windows updates it doesn't work.
I tried to press the monitor on the window and ctrl - alt - back space but it is not doing anything my screen remains black. The keyboard input passes through so (when i plug a monitor i see the task manager's green screen.) The switch monitor icon is grayed out.
