Second 2001FP detected for TwinView but DVI output is messed up
Since it seemed 3 displays were detected (with DFP-0 being some sort of phantom), I added the line
Option "UseDisplayDevice" "CRT-0, DFP-1"
And TwinView started up with 3200x1200! However, the colors are completely messed up on the DVI connected monitor. Also, it seems to mess up the display output on that channel completely since the console (which outputs via DVI) is also messed up (fonts look like they've been zoomed in on but poorly). I assume this means something is up with the frame buffer. Also, I had the nvidia logo set to off and it still showed up on the DVI side with the symptoms above.
