Hello,
I am running 4.3.12, and am trying to run my instance on dual monitors. However the monitor count (settings - display - video ) is disabled. Actually everything in that screen is disabled.
What am I missing?

Thanks

Did you shut down the VM first? (I don't mean suspend it).

You're missing the fact that your machine is either running, paused or saved state.

That's it.
I thought just saving it would be enough. Shutting it down allowed me to change it.
Thanks
