cranuaed Posted October 29, 2020 Share Posted October 29, 2020 Hi, everyone. I have my Hackintosh almost 100% working except for one minor issue that I can't seem to resolve. I have two monitors connected via DP->HDMI cables (no DP inputs on my monitors). If I boot with just one of them connected, everything works and I can connect the other one after booting. But if I try to boot with both connected, I get stuck with a black screen after the IOConsoleUsers: gIOScreenLock... message, before the Apple logo and progress bar appear. I have tried all the fixes I could find from the OpenCore install guide and WhateverGreen's FAQs, including: CSM both on and off in BIOS Patching VRAM Patching connector type to HDMI Adding -igfxmlr boot argument Anything else to try? The system is still perfectly usable, but it's annoying having to disconnect a monitor any time I need to reboot. Thanks in advance for any help.

HenryV Posted November 8, 2020 Share Posted November 8, 2020 What resolution(s) are you running for each monitor if you are using independent displays as opposed to a composite desktop? How much video memory do you have available? Enough to initialize both devices at the same time? Try significantly lowering the resolution of one or both monitors.
