ATI 6670 is properly recognized but won't see my monitor

[shiningstar]

Hi everyone,

I've had my hackintosh for almost a year and wanted to add a graphics card because the Intel HD4000 wasn't powerful enough.
I had a Asus 6670 laying around and put this card in followed some tutorials and got it to work. (I thought)

I did this mostly remote over VNC from my laptop and after running benchmarks to check if the video card was really working I checked the machine itself.

No screen....

I used the DVI port on my video card.
I have a new Kext installed.

in my plist i Have these flags for graphics:
<key>GraphicsEnabler</key>
<string>Yes</string>

<key>AtiConfig</Key>
<string>Pithecia</string>

<key>AtiPorts</Key>
<string>3</string>

I Use a Gigabyte With z77 chipset (GA-Z77X-D3H)

With the card installed I even can't access my bios (or at least i can't see it)

Any advice?
What settings do you recomend for the GPU in my bios?

Thanks in advance

Have you tried the HDMI port?
You can try another personality for your card. Changing the "AtiPorts" configuration, for example, to Kudzu instead of Pithecia, may get you a working DVI port.
