SOLVED: This fix is so simple. All You have to do is change Your SMBIOS Version to 6,1 (Mac Pro 2013)
This is because if You have a iMac's SMBIOS version (with the built-in display), the system will recognize only one display as the built-in one.
If You change the version to the Mac Pro one (that doesn't come with the display), You can use 2 or more monitors at the same time!
I'm right now using 2x 4K 60Hz monitors connected via display port to my Sapphire RX 580.
[Before the fix, the secondary monitor didn't work and after the boot logo it did goes black.]
FIX:
1.
- Open Your config.plist file in Clover and go to SMBIOS settings (Information Censored XD)
- And select the version menu
2.
- Select "MacPro6,1 - Mac Pro (Late 2013)..." Option
3.
- Save the config.plist file
4.
- And Reboot!
IMPORTANT: This Fix will turn off the Intel QuickSync and if You are using Final Cut Pro X You will not be able to export videos!!!
Done!!!
Enjoy Your secondary display via DisplayPort! =)
