Hackintosh Hdmi Fix -

This is a power management issue. The card falls asleep before the monitor wakes up.

Fix via SSDT: Create a custom SSDT to set PP_PhmSoftPowerPlayTable.

Simpler fix: Add amdgpu.modules=1 and -cdfb to boot-args. This forces the framebuffer to stay alive during sleep/wake cycles.

Add this to your iGPU DeviceProperties:

<key>hda-gfx</key>
<string>onboard-1</string>
<key>device-type</key>
<string>Intel HD Audio HDMI</string>

Then, ensure your AppleALC.kext is updated. You may also need to add alcdelay=1000 to your boot-args to force macOS to wait for the HDMI audio chip to initialize.

Once you have the right Platform ID, the real work begins.

# Check if GPU sees HDMI connector
ioreg -l | grep "HDMI"
# Check audio codec
cat /proc/asound/cards
# Show currently used framebuffer connectors (Intel)
ioreg -l | grep -A 20 "AppleIntelFramebuffer"

If none of this works, switch to DisplayPort (better compatibility) or use a DP-to-HDMI active adapter (e.g., Club3D or StarTech).
