Won't boot to dual monitors on 660 TI

[film_guy01]

So I have my hackintosh all up and running now (yay!!!!)

This is my setup:
A Gigabyte GA-Z77X-UD5H Motherboard
An Nvidia 660Ti Graphics card
An Intel i5 3570K CPU

The problem is I can't get dual monitors to work on my 660 Ti card.
I installed the NVIDIA Fermi >2GB Open CL patch
I installed the NVIDIA 670/680/690 Support patch
I have installed 10.8.2

But I still can't get a second monitor plugged into my graphics card to come on.
If I just have my HDMI cord attached and boot everything boots fine. If I plug in the HDMI and the DVI it just boots to a white screen on the HDMI side and does nothing on the DVI side.

If I boot on the DVI and then plug the HDMI in afterwards, they will both show up. But I can't boot with them both plugged in or I get a blank white screen.

I have my bios display settings set to "peg" (vs. IGFX or PCI)

What am I doing wrong? Have other people gotten dual monitor support working with the card?
Please advise.

Thanks!!

P.S. I'm loving this hackintosh business so far!

This is my setup:
A Gigabyte GA-Z77X-UD5H-B3 Motherboard F10 Bios
An EVGA 660Ti Graphics card
An Intel i5 3570K CPU

I am seeing the same issue with trying to boot with both displays attached in my configuration. Also, the video card will not wake from sleep.
No solution yet.

I am having the same issue with a EVGA GTX 650 SC 2GB.

My hackintosh setup: Asus x79 Sabertooth, i7 3930K, Mountain Lion 10.8.2 and dual DVI monitors.

If I boot with both monitors powered on, it boots to the mouse and whitescreen then stops. If I boot with the power off to 1 monitor, it boots fine. I can then power on the 2nd monitor and it works dual screen. I have the Nvidia driver loaded and it shows up as GTX 650 in "system".

This is a dual boot machine and it has no issues loading Windows 7 dual screen.

Dual Screen is just a hassle, but I am very happy with the operation overall. A "high-end" mac at a reasonable price - thanks tonymac
