Why do the refresh rates on computer monitors seem to always be 144hz or a multiple of 60?
In: Technology
What I remember is that displays’ refresh rate are usually 60Hz because the human brain processes vision at 60Hz. This means that if a light bub were to flicker at you for 60 times a second, you would see it as if it wasn’t flickering. This also means that if something flickers at less than 60Hz, you’d notice it.
But you’d quickly run into a problem. Sometimes like a flickering bulb, how bright a display is at any given moment is not constant i.e. the brightness of the bulb you see depends on when you look at it. One easy way to bypass this is to double the frequency of flickering (120Hz). That way, if two people were to look at a display at different times, they’re twice as likely to see the same thing. That goes for 180Hz, 240Hz, and so on. I don’t know about the 144Hz though.
