Hi Everyone. Sorry for the long post but I tried to include everything. And thanks in advance for all the help. I do not have a dGPU installed. I successfully built a Hackintosh back in September, and everything seems to be working just fine, besides dual monitor. I have searched in posts but none was left with an answer to the issue (none that I could find). I did my research using the resources below. I have 2 separate SSDs, one for windows, where dual monitor works properly without any issues, and the other one with Mojave 10.14.6. When booting into Mac, I can see the Apple logo on both screen, but midway through booting, the one connected to HDMI simply turns off, and the main display connected via DP starts flickering. After turning DP one off and on, it works properly but the second one displays no signal. I tried keeping the HDMI one off until it’s booted, but still nothing. I used latest Opencore Vanilla at the time. ACPI: SSDT-AWAC, SSDT-PLUG, SSDT-PMC, and SSDT-USBX. Kexts: AppleALC, IntelMausiEthernet, Lilu, NVMeFix, SMCProcessor, SMCSuperIO, VirtualSMC, and WhateverGreen. Drivers: HfsPlus, OpenCanopy, and OpenRuntime.
