How to Fix Need help fixing DisplayPort for multimonitor setup
This is a comprehensive guide to resolve the issue described in the post. Ensure you follow all steps carefully.
1. Prerequisites
- Hardware compatibility: Verify your exact Mac or PC model, CPU, GPU, and Wi-Fi/Bluetooth chipset.
- Required tools: Have OpenCore, OCLP, ProperTree, and a USB installer ready.
2. Compatibility Snapshot
- Check if your hardware is fully supported by the target macOS version. OCLP supports many models, but some have limitations.
3. Installation Preparation
- Configure your BIOS/UEFI settings appropriately.
- Create a USB installer matching your target macOS.
4. EFI and config.plist Review
- Review your EFI folder layout: BOOT, OC/ACPI, OC/Drivers, OC/Kexts, OC/Tools.
- Ensure essential kexts like Lilu, VirtualSMC, and WhateverGreen are present.
5. Post-Installation
- Run OCLP Post-Install Root Patch if you are on an unsupported Mac.
- Check graphics acceleration, Wi-Fi, and Bluetooth.
6. Troubleshooting
Reported issue
- For this specific issue, verify your kexts and patches are up to date.
- Check system logs and use verbose mode to identify errors.
Common Hackintosh/OCLP checks
- Stuck at Apple logo: Check verbose logs.
- No graphics acceleration: Verify Metal support.
7. Dual Boot and Advanced Configuration
- If dual booting, use separate disks when possible to avoid EFI overwrites.
8. Verification, Maintenance and Rollback
- Verify the fix worked and keep dated EFI archives.

Need help fixing DisplayPort for multimonitor setup
 | Hello! So, basically title. Hardware specs: CPU: AMD Ryzen 5 5600G GPU: AMD RX 580 8GB (not 2048SP - just a regular 580) Mobo: Asrock B450M Steel Legend Displays: two Xiaomi displays, one is 4K, the other one - FHD. I'd like to connect 4K over DP, and FHD over HDMI. What happens: the chance of DP working is really low. Usually, it starts fine, OpenCore (with driver for pretty boot menu) detects the 4K display, scales fine, then macOS's boot logs display on it correctly. When it goes to the lock screen - DP is "active", but there is no display. The second one works. If I'll try to reconnect it multiple times it *might* work. But usually it doesn't. I searched on YT, read dortania's guide on connector patching (post install guide) but I didn't understand / find anything related to my hardware No OC Simplify involved. [link] [comments] |
