iRissen Posted January 14, 2019 Share Posted January 14, 2019 Hello!I using two displays. One is connected by HDMI, second one is connected by DVI. When I trying to boot my macOS while both monitors are connected there is black screen after system boot. If I have only HDMI monitor connected, then system boot and working good. When I connect only DVI monitor then black screen again. How to fix that to use my two monitors. I using macOS Mojave 10.14.2. I have WEG and Lilu kexts in my folder. I don't have CSM option in BIOS.

davidljwang Posted March 1, 2019 Share Posted March 1, 2019 (edited) iRissen, you gave very little about your build. That said, I met with similar issue with RX 470 before. I finally found that I need to change boot mode from legacy BIOS to UEFI. After that, DVI works out of box. You may need to change setting in BIOS to boot from either "UEFI only" or "Both" with "UEFI first". Then when you install clover to your hard disk, select "Install for UEFI motherboard", as per this guide. https://clover-wiki.zetam.org/Installation Hope this helps.
