I'm sure there is no 'perfect setting', and it's not just because of B-fields. I have 3 partitions that I can boot up from: OS X, OS 9.1 (clean install for use in Classic), and my regular OS 9.1. When I'm booted into the regular 9.1, the screen on my monitor is set perfectly. When I boot into the Classic 9.1, the screen is moved 3 inches to the left, so some of it is cut off. I can adjust the screen so it's back to normal, but if I decide to boot into the regular 9.1, then that screen ends up being moved 3 inches to the right. It's like a tug of war between the two OS 9.1's. OS X is fine no matter what I do...go figure.
