Radeon Compatibility Guide - ATI/AMD Graphics Cards

My AMD Radeon R9 270X 2048MB video card, has DP, DVI-i, DVI-D, HDMI. How to use the HDMI input as a first screen, to make the DVI-i work with a VGA adapter, how should I do it? I used lilu + whatevergreen, I got the copy of the second screen on both screens, and the main screen disappeared, I had to put a double screen to see the main screen but on the second screen (DVI-i> VGA) the screen is a green shade.
Can you help me?
 
What is this issue? Has it been resolved in 10.13.6 and beyond. I ask as my RX560s are working fine with Intel HD4000. So, it would be nice to keep this computer reliable for many many moons.

If using your IGPU there is no need for rad de init. This is mainly used for people with no IGPU function, which would result in Black Screen after boot.
 
Back at it. Trying to get AMD Radeon up on my Z270X hack.

I extracted the IPX RX570 and returned it to Newegg. I put back my old NVidia GTX 950 card and booted my HS 10.13.6 OS
and at the same time ordered the Sapphire Pulse RX580 8GB, that everyone says is a drop in work out of the box. Came yesterday, replaced the NVidia card today. Booted into Windows 10 from the Clover dual boot of my Hack. Everything perfect so far.

Rebooted to Clover BOOT menu, and selected my HS OSX drive, having previously turned off the NVidia WedDriver flag in conflig.plist. Tried to boot : does not work, but not a black screen.

This time screen at least pops up the Apple icon, and 1/1000th of the bar load. Then system stops.

I tried with RadeonDeInit true and false, same result.

I tried to get to single user mode but it won't get to the shell prompt. This is what verbose mode shows. I confess I don't see the problem.
I have also attached the config.plist I'm using on the USB boot disk in compressed EFI.zip file. Am I using some incompatible Drivers64UEFI file that I'm not aware of?

The model is a iMac 18,2. Is that a problem? If so why would it work with the NVidia GTX 950?

Try 18.1 or 18.3.
Do you have lilu and Whatevergreen Kexts?
 
I will try the other models.

I have tried iMac 18,1, iMac 18,2 and iMac 18,3. All fail the same way. Take a look at the image of my screen in post #2588. It is the same posting no matter which model I use.

Try this modified EFI-folder and be sure to delete all fakePCIID kexts.

Thanks. I'll give it a try. How do I delete the fakePCIID kexts if they exist in /Library/Extension, and I can't get to single user mode?
