fortunately HDMI output working well by using Type-c to HDMI adapter. using default framebuffer settings. thank you for your helps. @Hervé @Jake Lo

I switched to prior downloaded EFI and then no log beside EFI anymore. so i must use MBP16,x?

I think my model is coffe lake plus. i.e 9th generation. cofe lake is 8th AFAIK. of course I tried 15,x more than 16,x.

if I am using this efi that I make using dortania guide, macOS booted but this log also exist beside EFI folder. please see that. meybe it's help to say CFG is locked. Archive.zip

I tested the HDMI port on Ubuntu live USB, and it worked.

@Hervé I have not succeeded yet. I test these SMBIOS by default framebuffer: MBP 15,1-2-3 and 16,1-2-3-4 after that test multiple framebuffer for con1 (and some case con2) for some SMBIOS specially MBP 16,1- 16,4, 15,2. I must set enable-backlight-registers-fix to 1 in PciRoot(0x0)/Pci(0x2,0x0), otherwise after booting laptop screen also is black and I must wait about 2-3 minutes to turn it on. in this situation, macOS is booted and I hear the wrong password sound or if I enter the password and hit enter, after the screen is turned on I see am logged in. Doesn't this give you a clue? I would be very grateful if you could help me

yes HDMI port on the laptop. what do you mean " The video output should still work with default DP type"? is this default framebuffer settings you talked about?: and if testing multiple SMBIOS with default framebuffer not worked, I must test multiple BusId for "01000900 00080000 C7010000" in con1? i.e: 01010900 00080000 C7010000 01020900 00080000 C7010000 01030900 00080000 C7010000 ... in framebuffer-con1-alldata? @Hervé

yes, only UHD 630 IGPU. then I must find proper bus id? I test atleast this: 01000900 00080000 87010000 02060A00 00080000 87010000 ---------------------------- 01000900 00080000 C7010000 02050A00 00080000 C7010000 ---------------------------- for all busIDs from 1 to 6 and another try by set this flags in boot args: igfxonln=1 agdpmod=vit9696

After adjusting DVMT to max, should still try set BusID in config.plist?

My HDMI is plugged in but not in IORegisteryExplore not showing that. please see screen shot. only display0 in AppleIntelFramebuffer@0 with connector type <02 00 00 00> which is my laptop display. AppleIntelFramebuffer@1 connector type is <00 08 00 00> , HDMI AppleIntelFramebuffer@2 is <00 04 00 00> i.e Display port. there is no display port on laptop. maybe it is type c. if I purchase a type-c to HDMI adapter, Is there any hope? or I must buy type-c to DP?

Hello everyone. My Dell latitude 5501 (i7 9850H, igpu only uhd 630 )working perfectly and running monterey 12.4. but HDMI not working and can not use my monitor. initially I use EFI posted by @Baio77 here. I try multiple methods to fix this. tried dortania guides for GPU patching and try a lot of BusIDs. try multiple smbios and boot args. trying for about 3 days for fixing this problem. But there was no success. at last, I Adjust DVMT using this method. now mac Os boot without framebuffer-fbmem and framebuffer-stolenmem but HDMI not responding yet. I thought by set DVMT Pre-allocated to 64M and DVMT Total GFX MEM to Max, problem must be solved. but it seems there is another problem there and I can not find that. my monitor is 2K and I have working with it by another hackintosh. Can you help me to fix this problem, please? thanks in advance. @Jake Lo @Hervé @Baio77 dell latitude 5501 EFI.zip dell latitude 5501 ioreg.zip

hi @Zenfection did you fix the problem? can you share EFI? I have same machine and like to install monterey.

@Myself5 thanks for sharing efi, Blackscreen issue (very dim screen actually) solved by this as detailed here:

refer to this page: https://osxinfo.net/konu/ati-7xxx-serisi-ekran-kartlarini-big-sur-de-full-calistirmak-opencore.20833/# I now can use my W5170M graphic card. thanks to Jake Lo and Hervé.

@Hervé I'm sorry, but I do not understand what you mean. is it means that W5170M must work? if the answer is yes, how to do it? thank you.
