It is you who doesn't understand. I've assumed nothing. I know exactly what I'm talking about. If 60hz flicker gives you a headache, you must be getting a lot of headaches since your fluorescent lights are flickering your entire room at 60hz hmm?
No, because my walls aren't made of crt screens. It only occurs if a crt is set at a 60Hz refresh rate with fluorescent lighting in the room. It occurs because the light and crt are not Synchronized. It doesnt happen if the lights have electronic ballasts. (Many don't).
