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

With computer displays only limitation is hardware. If I had to hazard a guess, 144Hz is there because that’s approximately maximum supported on widest range of hardware and 144Hz crystals were widely available and therefore cheap. Kind of how there’s a huge market for rollerblade ball bearings. Pretty much all of the power tools are using them. They are simply everywhere because they are cheap.
I was really hoping you were Lemmy’s 1996 rage in the cage account making every conversation about ball bearings
Haha, never heard of that.
Probably a reference to shittymorph? https://knowyourmeme.com/memes/the-undertaker-threw-mankind-off-hell-in-a-cell
Thanks.
Hell in a cell not rage in a cage. Oops
Despite all my hell I’m still just a rat in a cell
Tell me more about the ball bearing industry please!
Also subscribing for roller blade ball bearing facts
I remember getting ABEC-5 bearings for my blades back in the day. Felt like you were rolling on ice. ABEC-7 was an option, but they were so expensive and the gains were supposedly marginal. Still, I sometimes wonder about what they would’ve been like.
Really no different. The ABEC rating is about machine tolerances so they can spin really fast.
Roller blades and skateboards just don’t go that fast. Also the impacts and crap that they get off the ground damages them far more than what an industrial usage setting would.
They’re just fleecing customers
I had huge 100mm wheels, so I thought I felt the difference between ABEC-3 and -5, but maybe that was just placebo.
To quote Wikipedia:
ABEC only rates tolerances. Nothing else. They were rated bearings you had so they performed better than chinese knockoffs. If you wanted good stuff, go with Japanese, German or Korean.
I could be wrong and really don’t have the math in me, but I believer we’re taking about thousands of RPM here

You didn’t clean them weekly?
Man I did, but they were hockey skates (ice was not a thing here at the time) and I wanted to get every ounce of performance out of them.
Cleaning bearings, rotating wheels, relacing them cause my feet grew crazy for a while.
I was a weird kid though. Now I’m just a weird adult.

Haha, very little experience with that. But I do know rollerblade bearings are now most popular bearings thanks to low prices because of their initial popularity. Kind of how 18650 cell became popular because of laptops and is now virtually everywhere, including EVs. It’s all playing at large scale with manufacturers.
Not sure what’s the part you are interested in. I did learn about them in school, so perhaps I do have some knowledge you might find interesting.
I’m guessing you’re talking about 608 bearings?
Indeed.
Divide. They needed buffer room because 30 60 or 120hz aren’t always exactly 30, 60, or 120hz. Like you said 144 was just the cheapest that net or exceeded spec.
LCD crystals do have a theoretical maximum, but we don’t have display drivers or transmission standards that support those frequencies.
Didn’t mean LCD crystals, but just crystal oscillators that are used for timing.
