Not absolutely certain but Im fairly sure that I had 2 1920x1080 monitors working perfectly before learning about the changes for 4k. Others have built from the alternative thread and have reported it working without mentioning any uefi changes. Edit - and the selection of Intel rather than Auto is significant too, not certain about Catalina but for Mojave I think the settings are spot on and all those mentioned are significant.Nick, did you say you're running two 4K monitors after the UEFI modifiction ? Did you ever try 1080p monitors before you did that ? I'm thinking that maybe makes a difference whether or not dual monitors will work. Increasing DVMT to 96 MB may be the thing that is important here.
