A:Answer I would also like to know this. Many PWM dimmed displays give me migraines. To answer the question in the previous answer, yes, it is important. The flicker may not be perceptible to the naked eye but it can cause severe eye strain after a period of time. That's the difficult part about this; it takes some time with a device to determine if it will give me a migraine. It's unfortunate that it's not something easily tested by playing with it in a store (which is also lit with PWM lights above, making it harder to determine).
