Administrators Hervé Posted October 4, 2022 Administrators Share Posted October 4, 2022 For HD620 graphics, you should be injecting KBL frame buffer 0x59160000. 0x591b0000 is for HD630 though it's highly likely to work nevertheless. HD620 iGPU of i5-7300u CPU carries PCI id 0x5916 so no need to inject this of course (but doing it will cause no harm). Link to comment Share on other sites More sharing options...
Dell7280pl Posted October 4, 2022 Author Share Posted October 4, 2022 I changed platform-id from 1B59 to 1659 and that didn't change anything It's still the same Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 4, 2022 Administrators Share Posted October 4, 2022 I recommend you start with a basic set of graphics properties injection rather that what you currently use and that may be inadequate. I suggest you stick to the following set of properties and comment out all the rest of your properties by placing a # character in front of the keys: AAPL,ig-platform-id 00001659 DATA framebuffer-patch-enable 1 NUMBER framebuffer-fbmem 00009000 DATA framebuffer-stolenmem 00003001 DATA framebuffer-con1-enable 1 NUMBER framebuffer-con1-type 00080000 DATA You may then consider commenting out the PNLF section of your all-inclusive SSDT and add a SSDT-PNLF standard table that you may grab off the Dortania repo.

Dell7280pl Posted October 4, 2022 Author Share Posted October 4, 2022 I changed the config entries to the ones you provided I deleted the GPU entry from my SSDT and added the ssdt-pnlf It is still the same I do not understand this "a # character in front of the keys" can you explain?

Administrators Hervé Posted October 4, 2022 Administrators Share Posted October 4, 2022 You really should post your stuff because you've lost me here... Ideally, save an IOReg output from IORegistryExplorer app, zip it and attach it. You made a typo in your revised set of iGPU injected properties. It's of no consequence to your LCD display but it's likely to prevent HDMI output. Link to comment Share on other sites More sharing options...
Dell7280pl Posted October 4, 2022 Author Share Posted October 4, 2022 I change GFX0 to IGPU in my SSDT-PNFL ? I'm uploading the file IOREg: MacBook Pro.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 4, 2022 Administrators Share Posted October 4, 2022 I'm pretty sure your PNLF patched device des not attach to the iGPU. Please post a zipped copy of your bootloader's ACPI folder + config file. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted October 5, 2022 Administrators Share Posted October 5, 2022 Try these where I've removed references to GFX0 and replaced them by IGPU in the SSDT-PNLF table + renaming of GFX0 to IGPU in the OC config.
