<< Solved >> DisplayPort not working after Mojave Update

[AnDenPrangerMitEuch]

Hi,

I upgraded my PC with an MSI RX 580 ARMOR Graphics Card (1xDVI, 2xHDMI, 2x DP) after Nvidia doesn't release a driver. The new Graphics Card worked fine in High Sierra, then I installed the update to Mojave.. Now I have a problem: I have four monitors connected (1 DVI, 2 HDMI and 1 DP) and the DP-monitor doesn't get any signal. Why did DP stop working and much more important: How can I fix that?

CPU: Intel Core i5-7600k
Motherboard: MSI Z270 Gaming Pro
RAM: 16 GB DDR4
OS-SSD: Samsung 960 EVO 500GB

I have the exact same GPU and do not get a signal when booting to Clover. The only way to get it to work is boot with the iGPU and then later once in OSX attaching my 2 4k monitors via DisplayPort to the GPU. Here's a picture of my EFI folder, I'd attach it, but it's a little hefty at 49.5MBs).

Problem solved by Changing System Definitions from iMac 17,2 to Mac Pro 6,1, now all Screens are working fine. I tried several system definitions and Mac Pro 6,1 works best. Screenshots of Clover Configurator below.

You're Whatevergreen.kext and Lilu.kext are very old versions. Update them to the latest version and all will probably be fine.

now am getting 2 issue

1-would not boot directly to MAC logo

2-display port not working on the HDMI

how could I return everything like how it was before like booting normally without clover screen

and fix the display booting issue
