- Well I thought of that, so I persuaded the shop to let me switch off the
- fluorescents, and it did not seem to change the effect. But it did look
- like some kind of beating to me. Yes, I really see it chiefly with very
- light colors ( the white of the Windows desktop is a good one), and it
- is more obvious out of the side of my eye.
- The thing is that a 60 Hz refresh rate should be pleanty to be
- invisible- after all movies go at a refresh rate of about 30Hz, and the
- "phosphor" is extremely fast ( Ie, the screen really goes completely
- dark between frames with no phosphor persistence) and that does not
- drive one crazy with flicker.
