I've often wonder the effect of refresh rate. Back in the days of NTSC/PAL TV days, Americans had NTSC running at 60Hz and the UK ran at 50Hz refresh rates (same as the electricity supply runs out btw). This would yield American friends/colleagues comming to the UK and for a few weeks watching TV would complain about the flicker. Reason for this was their visual system had got used to the higher refresh rate and suddenly seeing something lower, stood out and once noticed, was hard to un-notice and would for them make for a noticeable flicker.
I've often wondered what effects refresh rate has upon the brain and how fast/how we process information and equally, how we adapt.
So with all that in mind, I wonder how old people who grew up with a 60hz TV compare to those accustomed to 50hz and if the statistics of cognitive decline are not the same - more interesting questions.
- ygra 7y agoPersonally, both 50 and 60 Hz are horribly flickery. Back when I used a CRT I couldn't stand anything below ~85 Hz and would get headaches. Now that the screen no longer flickers, I guess in terms of motion fluidity there's a perceivable difference between 50 and 60 Hz. Something I personally cannot unsee, though, is 2:3 pulldown, which is something you don't see in Europe (at the expense of slightly faster movies).
- joshspankit 7y agoI’m pretty convinced on the theory that some people see “faster” than others. Most people can be taught to notice flicker, but I really feel like some see more naturally.
