I got my Gretag Eye-One Display 2 colorimeter last night and have been playing with it today. If you don't have a colorimeter or access to one, here's what I've found to be the best settings:
Brightness = 0% (manual)
Contrast = 53% (manual)
Color settings: User Preset (I think these are factory defaults)
> Red = 100
> Green = 98
> Blue = 94
Color Management (software) = 2005fpw ICC color profile
Those are my settings, with the except of the 2005fpw color profile (I have a custom-calibrated on in there now). To test it out, look at these images on your 2005fpw:
GrayScale (you should see "8" in gray clearly at the end)
Another grayscale bar
Tokyo at Night
Tokyo at Night should come out very well. I can see all sorts of details in it now that I didn't see before.
