Hello,
I have dual OS hackintosh, with both Windows and High Sierra as OS.
I also have dual monitor setup, with both monitors being Dell U2515H.
Everything was working fine, but since yesterday I am not able to detect the second monitor while using the macOS. To make it clear, the monitors work fine when I boot on Windows, but I can only use one monitor when I boot on macOS.
What weirds me out is that the issue started yesterday. Before that all was good.
I have AMD Radeon R9 390X graphic card, and the monitors use DP-to-mDP connectors. (DP goes in graphic card, mDP goes in monitor). It's the default connector I received when I bought them.
Any idea how I can solve this? I tried some solutions but most of them seemed to be NVIDIA related. What I tried didn't help, and this is my first Hackintosh build so I kinda work with anxiety that I may screw things up.
Thank you for your time,
