As of an update I pulled in on Monday, monitors plugged into HDMI-0 and DP-1 are not detected i.e. they do not show up in the gnome display settings and remain inactive. However they are listed as displays in nvidia-settings.
The odd thing is DP-2 works: it shows up as a display in gnome settings. However, it’s not listed in nvidia-settings.
Before the update, I had all three monitors working with the built-in-display turned off, that is HDMI-0 and DP-1/2 enabled (both DPs with passive adapters).
The nvidia drivers were installed with RPM fusion https://rpmfusion.org/Howto/NVIDIA (akmod-nvidia) and I’ve copied the basic xorg config:
sudo cp /usr/share/X11/xorg.conf.d/nvidia.conf /etc/X11/xorg.conf.d/nvidia.conf
Here is my bug report log and relevant screenshots https://www.dropbox.com/s/t2294l5rubyivov/nvidia.tar.gz?dl=0.
Thanks for the help!
