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

It’s not by chance 60fps. It was chosen because power grid in USA is 60Hz, so it was easy and cheap way to synchronize frames without having additional timing hardware. As for 59.97, that was a 0.1% slowdown introduced when color TV was added to prevent cross-talk in chroma channels. Weird solution but it worked out fine. Today there’s no reason for sync anything with power grid but 60 is still a very convenient number as it’s easily divisible by many others.

I thought modern cameras compensate for that. Apparently not.
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.
Yup.
Huh, now that is interesting - our microwave’s clock continually edges forward until it’s a few minutes out from the oven clock right next to it. I wonder if that’s why. I’m in the UK and as far as I know, all our appliances are too, but maybe not?
