michelkastro Posted October 9, 2020 Share Posted October 9, 2020 (edited) 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. Edited October 9, 2020 by michelkastro Quote Link to comment Share on other sites More sharing options...

michelkastro Posted October 14, 2020 Author Share Posted October 14, 2020 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. 2 1 Quote Link to comment Share on other sites More sharing options...
fickerr Posted November 7, 2020 Share Posted November 7, 2020 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.

fickerr Posted November 8, 2020 Share Posted November 8, 2020 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.
