HELP: Can't Find Resolution Anywhere

[st3in]

I have the newest 27" Cinema Display with Mini Displayport. I'm connecting it via Displayport on the GTX 660 (non ti). I can't even get the hack to recognize the card in System Profiler when it's in. I can't even get a picture with a DVI monitor.

Running 10.8.2
Installed NVDIA drivers anyways
Tried a second card, doesn't work.

GraphicsEnabler=No?

I can't even access the OS when I have both monitors plugged in. Only one or the other and I have to reset the CMOS in between uses.

I GraphicsEnabler=No in MB then reset with the DVI monitor in the 660 but it only booted via Thunderbolt ACD.

Can you adjust the boot flags at the chameleon menu

 

[rick_wayne]

Only if I plug in one monitor. Either the ACD via MOBO Thunderbolt or an old VGA monitor. What flags would you suggest?

I have the 27" Apple CD with Mini Display Ports. To test the BIOS startup screen I plugged it directly into the Thunderbolt port (on the mainboard) and selected the internal graphics option in the BIOS. It showed the BIOS screen without problems and booted into Win8 ok. I should have let it boot into OSX just to check things out.

Power up with Cinema Display
Set GraphicsEnabler=No
Shut Down
Power Up and I can't access BIOS
RESET CMOS
Access Bios, Set InitDisplay to PEG
Restart
No Monitors work (unless I rest BIOS again)
