Indeed it makes sense to use iMac17,1 with this hardware.This doesn't work for me (DVI and HDMI). With both plugged in and either turned off, it boots as if both are on (DVI no input, HDMI scrambled). The hot plug method has zero effect on the system (whichever monitor was initially plugged in stays active, nothing on the other). Acceleration does work with either one plugged in at boot with no specific patches necessary. I've tried all the existing combos to no affect.
I did notice that MacPro 3,1 system definition will allow both monitors to work however I couldn't rearrange them at all (HDMI was master). Changing to 3,1 was an accident and I have iMessage all set up on 17,1 so I'd much rather use 17,1 and get that working.
Same here.
I have iMac 17,1. Haven't tried with MacPro 3,1.
I've spent a lot of time over the past week testing my port connections and the Framebuffer connectors. The desktop framebuffer we are injecting is 0x12190000, its contains 3 external connectors which are all Display Port(DP) connectors. As I've got a DP on my motherboard it seems to work for me to use this method. Your similarities here is that you both have HDMI and DVI, no native DP connector.
If you want to test editing your connectors from DP to HDMI (same as DVI) to see if you can get dual monitors running at the desktop using the hot plug method, I'm willing to help. It requires a little more work and you'll need to boot individually connected to each screen and make a copy of IOReg and upload them. [Guide] How to Make a Copy of IOReg Please name IOReg as connected screen, i.e HDMI.ioreg or DVI.ioreg.
Also document you port layout, 1x HDMI, 1xDVI 1x? if you have another port. in your config.plist Please use the 10.11-SKL-19120000-4_displays patch(credit : toleda) in Post#1 prior to getting each IOreg.
Make sure you have UniBeast/Installer that is capable of getting back into OS X if you want to test. A failsafe so to speak.
This isn't guaranteed to make dual monitors work with your port layout but there is a better chance with the connector edits. Hopefully in later release of OS X we'll get native support for this.
