[GUIDE] General Framebuffer Patching Guide (HDMI Black Screen Problem)

I start it from the SSD called Mojave. I attach the images.
I restart and I also take a picture of the Bootloader.

The config.plist file replaces it on the partition called EFI

Please run Clover Configurator, click the Mount EFI option as shown and capture/post the full Clover Configurator window.

Yes that's the right one. And the screenshot in Post #568 above is also correct. After you select Boot macOS from Mojave, please run IORegistryExplorer and export/upload the IOReg file. The modified framebuffer connector settings should take effect.

I know what you mean! :) The framebuffer settings are still not showing.

On your Asus, reboot and press F8 during the BIOS splash screen to bring up the Boot Menu. Then use the arrow keys to choose the Mojave SSD. This will ensure that the EFI folder on that disk is used.
 
I select the one in red...

Click on the one in red
  • If you are booting directly from the Mojave SSD...
  • If you are mounting EFI partition from the Mojave SSD...
  • And you are copying config.plist to the EFI/CLOVER folder on that EFI partition...
  • And the patches still do not take effect,
...then maybe the new config.plist is not being written to the EFI/CLOVER folder.

No further progress can be made until:
  • The modified config.plist is copied to the EFI partition of the Mojave SSD and verified that it was copied there properly.
The best way to check if the connector settings have been applied is to run IORegistryExplorer, scroll down to and click on IGPU@2, then check whether all of the framebuffer-con(x)-xxx parameters are showing on the right side.

You may have to figure this out on your own.

Temporarily disconnecting all other drives from the system might help (even disconnect EVO 960 if necessary).
 
Unfortunately I'm sure that the config.plist file is modified, because if I change smbios with 18.2 or 18.3 I see stripes on the monitor, and this gives me the confirmation that something is changing.
On my regio explorer file I noticed that on acpi-device IOACPIPIPlatform is not seriarizable is written. is this normal?
