Yes, but a decent PC monitor uses at least 70Hz.
But it's not only the frequency that matters. The "glow-time" of the
phosphor particles is also important. Remember those green and amber
monitors from the XTs? They had a low frequency, but it was not nearly as
irritating as 50Hz on a nowadays PC color monitor. And look at TV, it's
50Hz (Holland) and even interlaced, but I don't get a headache watching it.
I guess most MSX monitors have tubes that are "inbetween" PC monitors and TVs.
I once read an articale about the frequency of "TL balken" (Dutch term,
those long cyllindrical gas-based lamps). People found it harder to read
under 100Hz lamps than under 50Hz lamps. It had something to do with the
eye focus jumping from one word to the next and being interrupted by a
flash from the lamp. So maybe ever higher frequencies are not the way to go...
