[solved] HDMI out on HD620

[michmill]

Success! I was able to get HDMI working with just a few minor config.plist changes. Before I paved the machine and started over, I decided to try some of the patches you've suggested against other ig-platform-ids. Using ig-platform-id 0x591e0000 and redoing the SMBIOS, and few other tweaks as suggested in your last post I was able to get HDMI working.

config.plist attached for reference.

Thank you again, Rehabman. Now I just need to fix audio...

You need to patch the framebuffer connector for HDMI (ioreg shows an external monitor on the 0105 port).

I have the same problem on a Dell 5567, with an HD620 as well and a 10.14.3 hack. Reading through your config.plist there is no Properties section under Devices, or at least it is not being displayed for me in Xcode.
I have a thread about the same with no replies so far, any help you could shed, I would very much appreciate.

Got it, by using Hackintool and selecting the proper values for CPU and igpu I was able to find out the port number on my HDMI setup, so I uncommented the proper set of values on Xcode for @RehabMan plist file, restarted and got HDMI working without problems, I don't yet know if audio works with my VooDooHDA fix but I wll try later and let you know of the results, cheers!
