It's UHD620, and I fake it as HD620, but my screen doesn't have back light. Its id is E3A0. I can start the system, I can even watch a movie under flashlight.

I have got a new HP Probook 440G6.. and has the same processor, i5 8265u with UHD 620. I am able to install Mojave with the following guide
https://www.tonymacx86.com/threads/guide-hp-probook-elitebook-zbook-using-clover-uefi-hotpatch.261719

But, I'm able to boot to newly installed system, but display blinks, it goes dark for 10-12 seconds and come back for half a second.

Clover config used:
https://raw.githubusercontent.com/RehabMan/OS-X-Clover-Laptop-Config/master/config_HD615_620_630_640_650.plist

With other configs, display does comes up.. but no acceleration :|. Not sure where to look further, any help here is much appreciated.


Thanks

@RehabMan
This is happening to me, too. Without SSDT-PLNF.aml, the backlight is extremely dim. With it, I get the flickering as reported above. I have a Whiskey Lake i7-8565U with integrated UHD620 graphics. I'm not including problem reporting files because someone else already has, but if anyone wants them I can provide them.

also your 3rd party kexts should be installed to /Library/Extensions and not /System/Library/Extensions

config.plist, InjectKexts should be set to Detect

While I'm sure this is helpful to the quoted commenter, none of those issues are the cause of the problem. I've done all that properly, and the issue still persists.
