Typical patches for HDMI:
Here is a guide to the most effective fixes for HDMI video and audio on modern OpenCore setups. 1. Framebuffer and Connector Patching (The Direct Fix)
On a genuine Mac, these framebuffers are hardcoded and predictable. On a PC running macOS (a Hackintosh), the hardware is a chaotic mix of variables. You might have an AMD Radeon RX 580, but it’s connected to your monitor via HDMI, while macOS expects it to be connected via DisplayPort. Or, perhaps you are using an Intel iGPU (integrated graphics), and macOS is trying to push a signal through a port that physically doesn't exist on your motherboard.
Believe it or not, many "HDMI issues" are cable issues. macOS is terrible at handling degraded signals. Use a or an Ultra High Speed HDMI (48Gbps) . Do not use a 10-year-old cable. Also, try a DP-to-HDMI adapter . Often, converting DisplayPort (which macOS loves) to HDMI (which your monitor loves) bypasses the issue entirely.
Fixing HDMI on a Hackintosh is a rite of passage. It is a puzzle that requires equal parts software tweaking and hardware acceptance.
Most HDMI issues stem from macOS not correctly identifying the physical port on your motherboard or laptop. You need to tell macOS exactly which "connector" is your HDMI port. Identify Your iGPU: Dortania OpenCore Guide to find the correct AAPL,ig-platform-id
