Hello everyone. I just finished installing High Sierra 10.13.2 and got some problem with my hdmi video output.

 

Spec:
CPU : Core i5 4200m
GPU : Intel hd 4600 & Nvidia gtx765m (disabled by ssdt)
Resolution : 1920x1080
Audio : via vt1082
Clover : r4411

 

Work :
- Graphic QE/CI
- Audio Output
- Touchpad
- LAN
- Shutdown,Restart, Sleep
- Battery percentage

 

Not Work :
- HDMI
- Mic

 

Problem :
- HDMI video output not recognized. i already patching connector-type in framebuffer via clover, rename bod3 into hdau. *fyi : hdmi output video works perfectly when booting into el capitan. but since sierra update hdmi cant detected even i already patch it.

This same patch works on El Capitan?

I see you have 2 things going on.

1) you have layout-id 21 for audio in your DSDT/SSDT but have 33 on your Config file. 

2) you have port 204 disabled in the Config. You have HDMI enabled in 105, are you positive that's the correct port?

yes. it works.

 

1) i think thats hexadecimal of 33

2) hdmi patch which i used only

find:

01050900 00040000 87000000 02040900 00040000 87000000
replace:

01051200 00080000 87000000 03061200 00020000 87000000
 

i replace 0204 too because when i just patch 0105 port, hdmi still not working
