suwalski asks: "Often when I go over to someone's house to help them with 'computer stuff' (translation: free support), I notice that many people who don't know better still use 60Hz as their refresh rate. XP seems to automatically tune higher, but for the others, I immediately bump it up, because it hurts my eyes. They say they don't see the difference. Am I right to assume that low refresh rates that make my eyes water are not healthy? If people don't notice the low refresh rate, does it still damage their eyes? Anyone know of any studies or papers?"
