Here is part of my work (which took patient, brute-force trial and error to figure out). At the time that I discovered the solution, there were no guides that explained patching UHD630 with DP->DVI adapters (all guides said that adapters were not supported). Also, I don't like using the alldata binary patching format. It's just my personal preference. If your preference is to use alldata binary patches instead of individual con0, con1, con2 patches, that's fine with me. My original question here asks why the Dortania example uses con1, con2, and con3 when I think they should be using con0, con1 and con2.

Well, to verify/falsify, you need to check the source code of whatevergreen. I guess it's in here somewhere: https://github.com/acidanthera/WhateverGreen/blob/master/WhateverGreen/kern_fb.hpp Link to comment https://www.insanelymac.com/forum/topic/334899-intel-framebuffer-patching-using-whatevergreen/page/20/#findComment-2808780 Share on other sites More sharing options...
pkdesign Posted October 31, 2023 Share Posted October 31, 2023 (edited) I think this is the right place to post this 😉 When I go to System Preferences>Displays, the "Default for Display" set my monitor to 1920x1080. I have an LG 4K monitor that I have set to 2560x1440 (rather than 3840x2160 because it is too small!) Why isn’t the default for this display at least 2K or even better 4K? Is there a setting I have missed? My only boot args are: keepsyms=1 debug=0x100 alcid=7. Below is my device property <key>PciRoot(0x0)/Pci(0x2,0x0)</key> <dict> <key>AAPL,ig-platform-id</key> <data> AwCRPg== </data> <key>AAPL,slot-name</key> <string>Built In</string> <key>device_type</key> <string>Display controller</string> <key>model</key> <string>Intel UHD Graphics 630 (Desktop 9 Series)</string> </dict> Is there something else I need? System details in signature. Thanks!

miliuco Posted October 31, 2023 Share Posted October 31, 2023 @pkdesign With these settings my Intel 630 works fine on a 4K display: 1 Link to comment https://www.insanelymac.com/forum/topic/334899-intel-framebuffer-patching-using-whatevergreen/page/20/#findComment-2813009 Share on other sites More sharing options...
pkdesign Posted October 31, 2023 Share Posted October 31, 2023 Thanks. I used your settings for iGPU in headless mode and it works just fine. I probably need some of those new settings that I didn't have anyway. But my original issue (when I click on Default for Display in Preferences) the monitor still reverts back to 1920x1080. Shouldn't it deafutl to a 4K resolution? Its just cosmetic and not a real issue. I'm just constantly tweaking! 1 Link to comment https://www.insanelymac.com/forum/topic/334899-intel-framebuffer-patching-using-whatevergreen/page/20/#findComment-2813011 Share on other sites More sharing options...
miliuco Posted October 31, 2023 Share Posted October 31, 2023 @pkdesign Mine is 28" 4k, when I change SMBIOS or in the first boot after macOS install or update, sometimes I get Full HD resolution, but changing it to 2560x1440 this value remains between boots. Try changing color profile to Display P3 and comment.

pkdesign Posted November 1, 2023 Share Posted November 1, 2023 Changing the color profile doesn’t change this behavior.

prynhart Posted December 16, 2023 Share Posted December 16, 2023 I'm brand new to Hackintosh and am using a prebuilt EFI. I've got an HP 800 G1 and am trying to connect dual monitors to the 2 x onboard display port (i.e. iGPU only) in combination with Monterey. When I have only a single monitor connected via displayport, everything works fine. But as soon as I connect the second monitor, I get (at the EFI boot screen): OCC: Failed to set mode 2 (prev 1) with 1920x1200 resolution Halting on critical error I was hoping someone might be able to step me through what I need to do to modify the existing EFI to get my setup working with dual monitors ?
