@zzmadd I'm very curious about why some people have H.265/HEVC available and some do not, so I started what I hope will be a productive survey here. Let's see if we can figure out the difference(s) resulting in available or unavailable.

That's a cool idea!
Thanks for that @deeveedee
I'll put up mine soon.

@zzmadd After upgrading to Big Sur 11.2, I posted my updated VideoProc.app hardware detection and IORegistryExplorer 2.1 dump here.

Thanks a lot!!
I got the file.
I've also added my IOReg 2.1 and VideoProc screenshot on your build thread.
See you there!

Hello @Digital_Singer,

We should not quote huge sections of these guides. You said that your "motherboard is there". Are you asking a question?
Yes sorry, was trying to remove it but posted it by mistake.

I have the Asus Z390-a and UHD 630 graphics of the 9900k working on DP, I can't even remember exactly what worked but was able to get it patched even with my limited knowledge and it worked, Now trying to get Dual Monitor has I use this Hackintosh for music recording which is always best with two monitors. I already suppressed GTX 1070 with boot arguments. I was wondering to translate your device properties to xcode or propertree data entries. So I could enter it. Thanks in advance

The HDMI and DP ports are activated by the patch. Some questions:
  • Are you saying that DP port is working, but HDMI is not?
  • Are you using Clover or OpenCore?
  • Do you need help adding this patch to your config.plist?
  • Are you running Mojave or Catalina?
  • Which version of WhateverGreen are you using?

First Yes DP working and HDMI not, I only have the two on Asus Prime Z390-A board

OpenCore

if possible help patching would be appreciated, but I could do it myself if the data could be translated for OpenCore config.plist which I open in xcode or propertree.

Has an example "<key>AAPL,ig-platform-id</key> <data> / BwCbPg==" the data is not something that I could enter in config.plist in xcode. how can I translate this or if you don't mind entering the patch or checking the config.plist which I have included below.

I'm running catalina and using the second last WEG released, just installing the new one tonight.

Will follow-up in the morning when I power up the Hackintosh again. Will simply update this post so “refreshing” the webpage might be necessary.

Meanwhile, that strange looking text in <data> is Base64. Hackintool’s ’calculator’ page can be used to convert to and from Base64.
