Administrators Hervé Posted August 27, 2021 Administrators Share Posted August 27, 2021 What are those screenshots meant to show us? I'm seeing the icon of an external monitor, i.e. what would normally be shown as a 2nd display on a laptop or as main screen on a desktop or what you'd obtain with the SMBIOS of an iMac/MacPro. When running on a laptop with a MB/MBP SMBIOS, any properly detected built-in screen would be normally shown as a laptop screen. Could you remove those FakePCIID kexts and check if it makes any difference? Link to comment Share on other sites More sharing options...
lamatta17 Posted August 27, 2021 Author Share Posted August 27, 2021 Hello Hervé, after disabling the FakePCIID kexts and nvreset, there is only the ext. monitor. Link to comment Share on other sites More sharing options...
lamatta17 Posted August 30, 2021 Author Share Posted August 30, 2021 Got the following tips from Hervé: Try and: remove those FakePCIID kexts, they're all mostly deprecated now and should no longer required add igfxonln=1 boot arg change SKL framebuffer to recommended layout to 0x19160000 rather than 0x191b000 inject your EDID hex chain as an iGPU property. switch to MPB13,1 SMBIOS, a dual-core/HD540 model, rather than MPB13,3 which is a quad-core/dual-GPU (HD530+AMD Radeon Pro 450) Unfortunately, only the int. display runs choppy (You have helped me many times now, would like to show my appreciation. How can I donate to you?) Link to comment Share on other sites More sharing options...
lamatta17 Posted September 1, 2021 Author Share Posted September 1, 2021 In the meantime I have tried all AAPL,ig-platform-id's for this CPU. With and without: AAPL00,overwrite-no-connect string. SMBIOS MBP 13,3 / MBP 13,1 framebuffer-fbmem framebuffer-stolenmem boot arg igfxonln=1 / -igfxmlr / agdpmod=pikera / gdpmod=vit9696 Is there still a chance to get the 4k monitor running?

lamatta17 Posted September 8, 2021 Author Share Posted September 8, 2021 I give up. have tried (all) possibilities. i donate 50$ for the following configuration: 4k int. works HDMI ext. works Based on OC 070 or newer Maybe someone can remotely achieve this goal.
