Asus Geforce 980 GTX Poseidon - only one port works at a time.

[Runi]

Hi.
I am literally going out of my mind. I have the 980 GTX 4GB card installed and I have two monitors that I would like to use, one is a Dell 4k monitor and the other a Dell HD monitor. But the thing is I can only get a signal to one at a time. Should I not be able to have signals on all DP ports. I have also tried the HDMI for the second monitor but no luck. Is there something in Clover I have to do??

Or should I not at least be able to daisy chain the second monitor through the 4K monitor? when I try that I still get a black screen.

I also might add that I have a Asus Deluxe z97 mobo with a Thunderbolt EX II Dual card installed. It works fine in windows and shows up in the BIOS. I have followed the instructions on "no Safety" and 128 in cache size but still when i go into system overview, my OS X says "no thunderbolt device". So I can not even run the second monitor of the TB card...

I really need some guidance here!!!!

Is there a specific kext that is needed in the EFI. I do not have any installed specifically for graphics.

Here is a new thought.

Could it be that I am not achieving what I want because I am running iMac 14.2 system?

iMac14,2 is one of the recommended system profile for people with a Z97 Haswell system. It is what I use and many others use.

Thats why I use it, but I was thinking if there was some "iMac" behaviour that restricted me from using multiple monitors, since a iMac can only do mirroring.
But after a long investigation I am leaning towards that it might be that Inject Nvidia needs to be set to false and I think mine is set to true. I will know more later tonight when I get beck to the machine.

Correct, it should be false for a GTX 980. iMacs can do multi monitors though, and I can do multi monitors using my GTX 970 with the iMac14,2 system def.

SOLVED...

The "Inject Nvidia" was what caused the trouble..

And to think that it was so simple that I never thought of it.

anyway..now I have a 3840x2160 and 1920x1080p on the other monitor
