My guess would be that I place larger displays far enough away that my eyes aren't constantly refocusing. A better answer may be that I also benefit from displays below a certain proportion of my field of view. I try to work in open areas where I can relax my eyes periodically by looking out of windows, and being able to see around the screen is important for that.
