So, I have a PSP(2000) and I get a headache whenever I play it: not a bad one, just a sort of mild ache-behind-the-eyes. It was worse when I first started using it, and gradually got better over time, but it still happens.
I've tried all the brightness settings, playing in different lighting conditions, holding the PSP at different distances & taking breaks every so often, but none of that makes much difference.
I suspect this is due to some kind of eye strain, perhaps related to the refresh-rate of the PSP's screen. I've never had this problem with other portables or screens. I can (and sometimes do) stare at a DSi or laptop screen for hours on end and I'm fine.
I bought a cable to hook the PSP up to the TV, (and that's what I've been using to avoid the headaches as it looks OK on the smaller of my two TV's) but that kind of defeats the purpose of owning a handheld, plus the PSP screen just looks a lot better.
Has anyone else had this problem? Does anyone happen to know the refresh rate of a PSP-2000 screen? Any way around it, or must I stick with playing it on the TV?
