Okay, so I downloaded Universal Installer (UIInstaller) from PCWiz, opened it and clicked on the "Apply EFI String for Video Card" box and selected custom NVIDIA. It then prompts me for my card name, I entered "Nvidia GeForce 9500 GT," selected 1024MB (1GB) VRAM size and DVI-I /VGA.

When I go to System Info, it still appears that it is not working. See below


SyncMaster:
Resolution: 1920 x 1080 @ 60 Hz
Depth: 32-Bit Color
Core Image: Software
Main Display: Yes
Mirror: Off
Online: Yes
Quartz Extreme: Not Supported
QuartzGL: Supported
Display Connector:

There is an option to select VGA / DVI-I, I am not sure how this is different than DVI-I /VGA. Do you have any insight? I believe I followed your directions to the "T."
