Interesting hypotheses, though I still can't quite accept them as final. I seem to recall that the effect was much more noticeable, not only when sitting in front of the screen—basically enter the room and there it is. And I think that I've experimented with lower refresh rates too, at least I definitely had the time and inclination—but can't remember if the monitor allowed them with the available resolutions. It's stuck in my memory that only 60 Hz does this. When I get rich and have lots of free time, I'll probably buy a bunch of old CRTs just to dig to the roots of this.
