Flickering Curiosity?

N8F8 writes "Why do some people see monitor flicker more readily than others? I happen to be one of the lucky folks who can spot a 60Hz monitor from across the room. Most people seem oblivious to this flicker. Other people can only see it in their peripheral vision. I tried researching an answer and I stumbled on plenty of information about something called 'Critical Fusion Frequency'. There even appears to be quite a bit of research into this phenomena but I couldn't find much information on why flicker perception varies so greatly. Can anyone shed some (flicker-free) light on this?"

    Surprise! It's a natural phenomenon that fits a normal distribution!

    In CRT based TV's the high voltage power supply vibrates.

    Not to mention the macro item such as the speaker cone, buttons and knobs.

    At the micro level you have lots and lots of e- and plain old heat.

    Quick quiz,
    How many moving parts in a solid state piezo tweeter?

    The moment on the CRT's flyback is more than in that piezo tweeter.

    ever noticed flicker [ in periperal vision in my case] if you are looking off to one side of a monitor across the lab WHILE SOMETHING BUMPS YOUR HEAD?

    No need to smack yourself in the head - put the end of a plastic fork between your teeth and pluck it. Vibration goes into your skull, and you can see all kinds of cool flicker on a CRT.
