Ergonomics with multiple monitors

Using dual monitors has more or less become the norm these days but more and more people are using more than two and larger monitors or even TVs. It would seem that searching for ergo suggestions would show that the industry really hasn't caught up to this practice to really document it and give detailed suggestions about set up and best practices. I bring this up because I've added a third monitor and at times run as many as four. Without specific details, I've fallen back to some basics we learned early on and coupled that with some tidbits I've found in my research.

The distance from your eyes to your monitor should be consistent from one to the other. If you're in a somewhat fixed position, this means the monitors should form a curve or semi-circle.

Try to keep them the same size if you can. I have 2 wide screen monitors and 2 square screen types. They're all aligned across the top, 2 - 3 inches below line of sight. Because the wide screen monitors do not adjust vertically, I built a custom stand to keep them at the correct height.

Consider the duty of each screen. In my case, The one to the far right is a light duty screen that I only use for email and IMs, The main applications are on the left 2. I set it up this way to limit the amount of head turning and keeping the bulk of my work in the neutral position.
