I have seen posts about this before but not with the gtx650 before so I was wandering if anyone has this working with triple monitors?

My setup is:
i7 3770
Z77X-UD5H
GB GTX650 2GBs

I had the HD4000 working fine on it's own however after a month or so I was able to get my hands on a GTX650 and it was a simple process to get it to work by simply disabling "Graphics Enabler". At the moment I am running OS X 10.8.3 with dual screens (DVI and VGA) out of the GTX650 but was wandering if there is anyway to put the HD4000 to good use?

I appreciate if anyone can point me in the right direction.
Cheers!

Try adding the below string into your into org.chameleon.Boot.plist. You would then need to set the internal graphics to boot first in your BIOS.

<string>7f0000000100000001000000730000000200000002 010c00d041030a000000000101060000027fff04002c000000 4100410050004c002c00690067002d0070006c006100740066 006f0072006d002d0069006400000008000000050062011400 00006800640061002d0067006600780000000d0000006f6e62 6f6172642d31</string>

WOW! This actually worked! One thing tho is when turning the system on the main display which is connected through DVI to the GTX650 was all garbage but unplugging it then plugging it back in made everything run fine. I know I am being picky here, but is there any way to fix that? Also does this bring any performance issues that you are aware of?

Just to register here, my monitors are connected in this configuration:
1080p TV: VGA (HD4000)
23" HD Monitor: DVI (GTX650)
19" Monitor: VGA (GTX650)


Just out of curiosity what does that string mean and do?
In any case, thank you so much, accurate and straight to the point.

The Display actually fixed itself so everything is working really well! Only thing I have noticed is After Effects seems to think CUDA is not installed so wont allow RayTracing to be offloaded to the GPU. I'll look around for that in forums but if you have a solution to that too, I would very much welcome it!

Thank you
