I have an issue where at times, I enable my 3 monitors and the right one won't initialise.
It's strange because if I switch to my "middle and right" profile, DF can still enable the right monitor.
It's as if the "all 3 monitor" profile has become either corrupt or the "monitorid#" or whatever unique code you have for it, is getting lost?
I can go into significantly more detail, suffice to say this is a regular occurrence and quite annoying. Been going on for at least a month now (so a couple of beta versions)
This is fixed by manually going into monitor configuration, re-setting up a profile and re-saving it for "all 3 monitor".
What I'd like to do, is save / collect some data from my machine next time the error occurs, then fix it and compare the saved data, see what's broken.
I generally found this problem was due to me having monitors entirely powered off, it hasn't come up in a while for me personally. I don't do ANY display fusion actions, without all monitors in a turned on state - even if it's standby.
