I have run into an issue with dual monitors that might be less unique than I might think, although I haven't been able to find this exact issue anywhere.
I have an OSx86 Lion (10.7.3) system with a GeForce GT 620 PCIe (EVGA), and both monitors will go into "Sleep Mode" when they're both plugged in. No matter what port I use, as long as I just have one plugged in, everything works fine. I've tried NVEnabler, which locks up at:
NVEnabler: probe: ROM shadow enable
I have also tried installing official GeForce/Quadro drivers from nVidia's site for 10.7.3, which gave me native resolutions, but didn't fix the dual monitor issue.

Thanks in advance
