If both HDMI ports are working properly (i.e. synchronizing properly when Mojave changes resolution during boot), but the two DP ports are not, then I suspect the firmware on the monitor. Have you tried switching to a lower resolution on the DP input and then rebooting with DP-to-DP to see whether the login screen appears without needing to power cycle the monitor?Yes, I've tried both HDMI-to-HDMI connections and they work. But I noticed that the colors using the HDMI connection are over-saturated (a bit too much, it seems to me) compared to the use of DVI and DP connections.
I will try to change the preset calibration options available Via the monitor OSD menu.
Your CLOVER and IOReg configurations both look correct. IGPU@2 is working properly with headless platform ID 0x3E980003.OK. Done, thank You
For the post-installation phase I used Multibeast v. 11.2.1: the "drivers64UEFI" folder installed with multibeast to replace with the one according to your guide was a little different from the one indicated in your guide:

I don't know if this could have created a problem
