Hmmmm, just read back over this thread. Am wanting to know if all is well with the Asus RX 580 card. Newegg has them for $199. I would like to buy and use in Mojave!
hey my Asus works fine now. I realised as I use a Dell monitor I needed to force RGB mode. This fixed the strange display port issue I was seeing. I now use whatever green kext as I have my igpu enabled for quick sync.

Has anyone tried injecting the EDID? did not help me but perhaps in conjunction with another option!!
I have the XFX GTS 580 8gb, perfect on one monitor, but black screen on the HDMI when used as a 2nd display
and hangs the system on my old x79..

stuck the same card in my mates new 9700k build on HS
and he gets two monitors but no bios or clover screens!!

Edit I solved the issue by removing the CSMVideodriver for hirez clover screens, now all screens work
