Thinking over my reactions to these flashes.

I'm sensitive to anything from turn signals and hazard lights, which usually run at about 3 hz, to ambulance and construction safety lights, which run a lot faster, to flourescent bulbs as they're burning out, which drop to 60 hz in North America or 50 hz in Europe. With the Bucha effect the most common danger zone is 1 to 20 hz, and with photosensitive epilepsy it's 3 to 30 hz, though there's a lot of individual variation.

If I can track down how quickly each device renders animation, that may help. And it may be easier to find one with animation speeds below, say, 1.5 flashes/second than above 60 flashes/second.

Does anyone know where to find that info? A lot of the "screen refresh rate" info refers to the full screen refresh after x pages, not the possible refreshes per second.

I would need to look into more keyboard navigation options instead of the mouse. I already use Page Down and other nav keys to cut down on scrolling animation.
