Dual monitor not working Vega 64 Nitro+

13 posts in this topic

Recommended Posts

I am not lazy so I read several articles on the forum for this problem, but after 14 days I am desperate.
I will donate or pay someone for his time if someone could help me.

I can install Mojave 10.4.2 or HS 10.3.6 with one monitor setup but I am not able to connect a second one.
My Vega has 2xDP and 2xHDMI. As my monitors are 2560x1600 I want to use DPorts, but only the first DP works.
If I connect the second monitor, I am getting a black screen just before the login screen.

On the same hardware I am able to run dual monitors with NVIDIA Titan Black on Sierra.
But I want to switch to Vega because of no NVIDIA support for the future.

What I've already tried:
- clean install of MacOS Mojave/HS
- I am using SMBIOS iMac 14,2, because newer iMacs SMBIOSes don't work for me
- I've tried also SMBIOS MacPro 6,1 because some users reported success with dual monitors
- I've tried WhatEverGreen and Vegagraphicsfixup.kext in /L/E
- and I've tried several patches what I've found on the forums...

I don't know if WhatEverGreen needs some keys or framebuffers etc., I don't have integrated Intel Graphics at all.

One last thing: I have a DSDT.aml for my mainboard from one user. I did not make it alone because it is about my knowledge.
I used it for 3 years (in 10.11 and 10.12) because I my USB ports doesn't work without it.
I don't know if this has an influence on the Vega graphics too???

Please, please, if someone can help me... thank you.

ahh sorry, I added my specs to the first post (i had them in my profile only :-)

Please upload your entire EFI folder. If you have any 3rd Party kexts installed in either S/L/E or L/E please move them to EFI/Clover/kexts/Other folder before uploading. 

Here is an EFI folder that should be correct enough for your system, add your CPUPM SSDT and DSDT to it but nothing else.

Thank you for your help!

 

I deleted all extra kexts from L/E (see screenshot). I ran KextUtility for permission repair and new cache.

Then I replaced the EFI with yours, I added only my DSDT.aml. I don't have my own SSDT (I didn't need one in the past).

I can't boot even to single monitor, too many errors and after it hangs for 60 sec. a reboot follows. (see photo).

 

I am attaching my original EFI after 10.4.2 clean install - with this I can boot o.k. to single monitor

and Vega works o.k. with single monitor. I am not able to upload more then 10MB, so here is an external link.

I did a test with Windows10 (God, I hate Windows :-) just to check Vega with 2 monitors, everything worked, so my hardware is o.k.

Dual 4k @ 60Hz working on a RX 580 using both display ports, to get this to work I needed Lilu.kext and WhatEverGreen.kext. Nothing fancy done in config.plist. it just works

 

Note, HDMI and DVI ports do not give me the resolutions I needed so I don't use them.

My bad I forgot to remove the SSDTs from another setup in the EFI/Clover/ACPI/patched folder. You should remove all of those, just add your DSDT there. With the EFI gave you it uses VirtualSMC so there is no need for FakeSMC anymore but you should only need to move the AppleIntelE1000e Kexts to EFI/Clover/kexts/other folder and delete that and FakeSMC from L/E and repair permissions.

Hallo again, I did replace the EFI folder. The result is the same, I can boot only to single monitor setup, if I connect the second monitor, both monitors get black during the Aplle loading bar screen (just before the login screen).
