Hello,

I did a fresh install on my old hardware with Mojave 10.14.6. Everything went well except that when I shutdown the PC a signal or power is still being sent to my monitor. My monitor will not go to sleep. This doesn't happen with my other builds. Also there is a red light on my adapter for my HDMI plug in and it should be off when I shutdown but is still on signaling that a signal is still being sent. I have tried several things. I checked off the Fix Shutdown in Clover Configurator, I changed the SMBIOS from 14.2 to 17.1. I changed the ig-platform-id to 0x1912000. I added change GFX0 to IGPU in Patches. Still nothing.

I have the following hardware:

Intel i5-6500
Gigabyte Z170N-Gaming 5
Samsung MZHPV256HDGL
8gb Memory Ram

I am using Intel Graphics 530. I have attached the config.plist. Any advice would be greatly appreciated.

@aztlan78,

Have never seen nor heard of this ... does not make sense ... if the system shuts down ok then the CPU and thus the IGPU has no power so no signal should be present.

I think the only way it could happen is if you are using an active display adapter to (EG HDMI to VGA) in which case it's most likely pulling standby power from the motherboard, USB, external power ... etc.

Cheers
Jay
