Getting this to work was a rather annoying process, as countless threads asking for help attest to. I somehow trial-and-errored my way to a configuration that works better than ever before, including a 2640x1440 resolution on the DVI port that exceeds the maximum listed in Intel's specs. Even SideCar works!

Here's the relevant section of config.plist:


XML:
<dict>
      <key>PciRoot(0x0)/Pci(0x1b,0x0)</key>
      <dict>
        <key>layout-id</key>
        <data>AQAAAA==</data>
      </dict>
      <key>PciRoot(0x0)/Pci(0x2,0x0)</key>
      <dict>
        <key>AAPL,ig-platform-id</key>
        <data>AAA7GQ==</data>
        <key>framebuffer-patch-enable</key>
        <data>AQAAAA==</data>
        <key>complete-modeset</key>
        <data>AQAAAA==</data>
        <key>device-id</key>
        <data>EhkAAA==</data>
      </dict>
</dict>

I'm using ig-platform-id 193B0000, not the recommended 1912000. The latter would either just turn black during boot, or not allow any resolution above 1920x1200. (Had I known that to be the official maximum, I would have probably stopped trying at that point. Ignorance is bliss!)

Also setting device-id and using the complete-modest option. I added both at the same time, and it's therefore possible that either one is enough to get it working. But I'm not going to touch it for a while just to find out.

Update: I updated. Regular installation of the Big Sur Public Beta Update from 10.15.5 worked with no actual problems. Somewhat nerve-wracking due to many reboots, several long phases without visible progress, and lots of scary messages scrolling by fast.

Matt your a life saver! Your little trick did the trick!

However with one exception. No DisplayPort output. Only working on HDMI.

Not a big deal.

At least now. I can put my 5700 XT in another build and still retain my Opencore setup on the old system
just using the onboard graphics.

Thank you

Thanks for the info, I also have Asus Z170I PRO GAMING Mini ITX + i7-6700 HD530,running on High Sierra,I tried your method but no luck.
I realized that you are using laptop/mobile and laptop ACPI, is there any reason/benefit for doing so?

ig-platform-id from 00001219 to your suggestion of 193B0000 gives my Optiplex 3040 i5 6500 to go from QHD to UHD, but with the loss of DP Audio and 2GB to 31Mb.
