Radeon HD 7790 Dual Monitors Causes Hang

[JBud]

Hello,

 

Upon request I will provide any information needed.

 

I am running OS X 10.10 with a Radeon HD 7790 (New AMD8000 drivers included which give native support for this card)

 

When I connect a 2nd monitor the main display flashes and the 2nd display initializes, however there is no display. The main display still works, however I believe the graphics drivers hang, I can move the mouse, but everything else on the screen freezes. Here's the strange part: I tried this several times, and about 1 out of every 4 times, the second display works perfectly. 

 

I am fairly new to hackintoshes, but I have a feeling I may not be using the proper framebuffer personality. With this card being newly supported, I have no idea where to start.

 

If you have experienced a similar issue with your dual monitor setup and/or have resolved a similar issue please don't hesitate to reply to this post!

Dual configurations are just not supported on this card. In other words, Bonaire and Hawaii kexts are not even beta from my point of view.
