I have an RX 580 and I have macOS Mojave.

I can't activate 03 monitors, only 02 monitors on the HDMI ports and the DPI is off.

Is it possible to connect 03 monitors in the hackintosh?

Can anyone help me or teach the steps?

Thank you very much.

I have an Asus ROG MAXIMUS XI HERO WI-FI(disabled) and I already tried with csm enabled and disabled.
I use OC 0.6.0.
DSDT was made with 02 monitors;

In reality, no DisplayPort works. After installing the clover and placing the ACPI Patch and AppleGraphicsDevicePolicy I had the 3 monitors and removing WhateverGreen.kext worked. I did not succeed with the same procedure in the O.C.

so, does it work now or not with DP?

I have the same problem. RX580 2 Monitors setup via HDMI working with Catalina

Trying to add a 3. monitor via display port doesn't work.

When booting clover is viewed via display port, as well as the apple booting logo, until it flashes (when graphics driver load?) then the monitor connected via DP is black and the other 2 are the only ones working.

adding Lilu and Whatevergreen kext (which I use on my hackintosh book but thought I don't need it on the desktop) fixed it. 2 HDMI + 1 DP for 3 Monitors works fine without errors.

I managed to connect the 3 monitors with SMBIOS MacPro7,1and iMacPro1,1
