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

    72 Hz was used as a refresh rate for CRT monitors back in the day. Specifically because it was the average threshold that no users reported discomfort from CRT flicker. And 72 * 2.

    It is likely a holdover from that era. I think from there, it is a multiple of 24 HZ so movie content scaled smoothly without tearing before vsync? Last part is a guess.

      144Hz is not a holdover in the case of computer monitors. It’s the maximum bandwidth you can push through DVI-D Dual-link at 1080p, which was the only standard that could support that refresh rate when they began producing LCD monitors built to run 144Hz.
