Had this reflection that 144hz screens where the only type of screen I knew, that was not a multiple of 60. 60 Hz - 120hz - 240hz - 360hz

And in the middle 144hz Is there a reason why all follow this 60 rule, and if so, why is 144hz here

    Funny effect, though - many cheap electronics (think coffee makers and microwave ovens) use the line frequency as a time base. Taking a 60Hz or 50Hz appliance and plugging it into the other causes the clock to be off.

      Not only that, but the grid frequency is not perfect and oscillates a bit constantly.

      Investigators can then take the background electrical noise in audio recordings, look at the spectrum, and pinpoint the moment in time they were recorded based on the specific oscillations heard.
