"Place monitor so top line of screen is at or below eye level." I've very commonly heard ergonomics experts suggest having the top bezel of your monitor be at eye level which seems like it would be about right for the person in the photo if he wasn't hunching over, which is a problem but seemingly not one related to the height of his monitors. I believe a constant extreme downward neck bend would be bad, the idea is that if the monitor's top is about eye level you can scan down to see it primarily just with your eyes without actually having to tilt your neck too much, which is quite different than the sort of extreme neck bending I believe you mean when it comes to certain types of cellphone usage.
