Teress Posted May 29, 2018 Author Share Posted May 29, 2018 (edited) @Pavo When I buy second gpu - RX550 - will it work together with my RX560? I am asking because the GTX1030 together with RX560 is not playing well as described above.

Honestly have no clue, I use a RX 480/580 and have no issues using 3x monitors at all without any patches or kext.

Teress Posted May 30, 2018 Author Share Posted May 30, 2018 @Pavo My Hack can't sleep even with your clover files, tried different darkwake modes but now I'm out of ideas. I click sleep, screens go black, but computer is still running, I waited 5 minutes. Can you help me to solve sleep? I am prepared to pay for it when it will work. Thanks.

Teress Posted June 12, 2018 Author Share Posted June 12, 2018 @Pavo Hello, I have new discovery. I bought second RX 560 4GB just for the one display that was not working as a third display on the first RX560. I now what? It also does not work. My setup and plan is now like this. GPU1 connected via DP to main Display1. GPU2 connected via HDMI and DVI to Display2 and 3. When I start computer, my bios post messages are on display1 and 3 mirrored. When OS boots, display1 and 2 are working, display3 went black. So there is definatelly any bottleneck which restrics to run only 2 displays together from 2 RX 560s. Strange is, that when I install only single HD5770, it can drive all 3 display out-of-box without any issue. Do you have now any idea, what could causing this stupid behaviour?

It could be SMBIOS restricting the amount of displays, I think AppleGraphicsPolicy would cause this, I do not know the patch though.

Teress Posted June 12, 2018 Author Share Posted June 12, 2018 I am using MacPro SMBIOS, there shpuld be no restriction. And even with this same SMBIOS I can run HD5770 wotj 3 displays without problem, so it should not be related to SMBIOS I think.

I switched to Linux where everything is much more smooth and powerfull than on the same machine under MacOS.
