Skylake Intel HD 530 Integrated Graphics Working as of 10.11.4

Can you boot with the config.plist I uploaded and check hot plugging your DVI monitor. If its an active adapter it doesn't matter its the port that counts. We can look at the AppleIntelSKLGraphicsFramebuffer.kext with Hexfield and extract the binary for patching, might not need to if your DP acts in the same way as mine.

I tried your config.plist (without the edits) but second screen does not get a signal after hotplugging. Tried both displays as master.

First post but have been following this thread and trying a few different configurations on my system.
I have DP and HDMI on my board. I am able to get both monitors working with no artifacts and 1536 MB using the hot plug method. Only issue is the DP monitor is not at the correct resolution (1280x1024 instead of 1920x1080).

Add the HDMI connector edit for Port 0x5 to your config.plist

Keeping your mDP/DVI monitor as primary, hot plug the HDMI connection and post your results.

Welcome to the forums and thanks for posting your results. At this stage it seems DP+HDMI are a good combination for the workaround with dual monitors on HD530. What steps have you taken for dual screens?
Does your DP monitor boot to the correct resolution on its own?

I have tried many different combinations of injecting intel (+/-), ig-platform-id (0x1912000 or empty), and a few different guesses with the port number (0x01, 0x07, or empty). I have also tried these combinations with having only the HDMI or DP plugged in and then plugging in the other later after booting.

I have the AppleIntelSKLGraphicsFramebuffer.kext enabled currently.

I am able to boot the DP display on its own and have full resolution.

How many monitors can you have with Intel HD 530 in OS X?

Is this correct ?
Hotplugging does not work yet after this edit...

Can you make a copy of IOReg with both screens connected and working. [Guide] How to Make a Copy of IOReg | tonymacx86.com IOregistry Explorer App is at the bottom of Post#1. Could you also upload your config.plist, before you do remove serial number and custom RtVariables edits if you've done them.

HD530 supports 3 displays. Currently in OS X one at boot and one added at the desktop depending on ports.

No other ideas at this time. Thanks for testing.
