HDMI issue on SKL laptop spoofed as KBL with macOS Sonoma

Hi @Francesco Guagnano 

 

Try add this args too:

 

swd_panic=1 agdpmode=vit9696 

 

Maybe you can try close your Laptop Monitor after or when you did the start boot

 

And you maybe try mine DeviceProperties

 

DeviceProperties'IntelHDMI.plist.zip

@Max.1974 With your configuration the situation got worse because both monitors go black. Also if I try to start the system with my configuration by closing the laptop monitor, the external monitor starts to flicker badly.

The boot-arg agdpmode=vit9696 is completely useless in your case because it's for external GPUs.

 

You really need to learn the fundamentals of framebuffer patching in order to fix this on your system instead of just trying random stuff.

Here the link to the Manual to make working.    https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md  

 

My laptop work with that config and another.

 

Try if you wanted. 

 

DeviceProperties 2 Option.plist.zip

 

Suggest you use AIDA64 to see exactly what is the specs of your Device intel video card. Report only Hardware. 

 

The boot-args is for test, so you not need use them if not work for you. 

 

The best fundamentals is here from Master of Masters

@Max.1974 With your latest configuration the situation is the same as that for which I opened the post.

[Max.1974]

Need check with Windows and run AIDA64 to see what hardware is yours. Try extract a Report. 

 

Don't give up, Hackintosh is this!! Not a Exactus Science

 

Happy New Year!!

Here my config for UHD 620 i5-7200-U Kaby Lake

 

Works nice with 4K 2160p60 on Youtube, not freezing or lagging. 

 

LCD (LVS) and HDMI working together 

 

You can extract your Framebuffers using WEG Debug with -igfxdump on boot args and change your parameters 

 

Don't give up

After one year I did not resolve the problem. I’m using the hdmi hot plugging it after the system boot. I gave up. I’m sorry. 😞

Do you think is a good idea ask help to Olarila guys through their consulting?

Hi my friend. It’s nice idea @Francesco Guagnano  my friend @MaLd0n it’s a great coder and he can fix it very well. Call him on PM. 

An observation if I use cable hdmi 2.0 it’s to much better than use some cables 1.4. I have some cables that not works and gave me black screen. It’s necessary get 2.0 hdmi quality cable.
