"50hz is likely to cause epileptic seizures, while 60hz is not."
Ah ... being something of a console novice, this might explain the sudden and quite overwhelming feeling of travel-sickness I developed whilst playing Black for the first time and leaving it on the default 50Hz setting ...

yup, that's exactly why. i used to get really ill when i was on the computer too long, but once i'd changed it to 120hz it stopped. It's been 3 years and i've yet to get that feeling again from my computer.
