you only have:

SSDT.aml

in your sorted order, you need to list all files in there that is in your patched folder

Read post #1, "Checking your work".
There are several things missing that are very obviously seen in ioreg as per that section in the guide...
- "hda-gfx" is not injected on HDEF (it is only seen on IGPU)
- no HDMI device is plugged in
- neither connector is patched for HDMI (no patches for it in config.plist at all...)

No sense in trying additional experiments until you correct the above problems.

Look at your Clover bootlog to see which SSDTs are being loaded from ACPI/patched
(it may surprise you... and point you to mistakes).

you have patched hda-gfx on your IGPU

but you also need to patch hda-gfx for HDEF as well

also according to your origin folder, you should have in your Patched folder:

SSDT.aml
SSDT-0.aml
SSDT-1.aml
SSDT-2.aml
SSDT-3.aml
SSDT-7.aml

and you also need to have a sorted order in your config.plist (the list above)

Thanks fearteach. How to patch hda-gfx to hdef?? I tired to apply intel 4000 low resolution patch but it only apply to igpu/_dsm

I made mistake. should it be rename to match like at origin ssdt order?

EDIT: I put my new ssdt and config.plist..
