I finally was able to put display port working..

After clean install of your probook guide, had to change on IGPU DSDT the device id to 0x0D260007

Thanks for everything

I'm having the exact same problem of not being able to get the display port working.

I have searched and I either don't understand what exactly you changed or I have no clue where to change on IGPU DSDT the device id to 0x0D260007.

Any help on how to do that would be greatly appreciated.

ig-platform-id is set in SSDT-IGPU.aml.

I've searched the forum and google but I'm not finding a clear set of instructions on how to update the SSDT-IGPU.aml

I assume it is not a simple find and replace? I opened the file with MaciASL and found the references for ig-platform-id for my device (Intel HD 4600) but the data for ig-platform-id seems to be in another format.

This is my fist laptop hack and I apologize if I am asking basic questions.

Edit SSDT-IGPU.dsl, then use ./build.sh as per guide.

That worked great!! Thanks for your help. I would considered this thread solved even though I did not initially open it.

Just incase anyone else is following and wants to replicate

To solve no Display Port output on a HP ProBook 640 G1:

With MaciASL open ~/Projects/probook.git/hotpatch/SSDD-IPGU.dsl

Search for Haswell/HD4600

There you will find the reference to AAPL,ig-platform-id

Replace the existing values with 0x07, 0x00, 0x26, 0x0d

Save the file and run ./build.sh per https://www.tonymacx86.com/threads/...book-using-clover-uefi-hotpatch-10-11.189416/ . Look for the section "ACPI configuration" and follow the guide again until the section "Final config.plist"

Reboot and enjoy your Display Port output :)

Friend! You saved my life!
 
Note that this change is incorporated into the latest ProBook github.

Along with a couple of other fixes:
- brightness range would be wrong without the appropriate patch
- done for 8x0 G1 and 6x0 G1 (Haswell)

We'll see if other Haswell models run into the same issue.
