Huh? This seems a bit odd.

I assume it saves battery. You don't really need a super high refresh rate if you're doing things like staring at static text.

You might not need it but you'll want it.

Personally I can't see a difference between 60Hz and 120Hz in phones, so I usually disable the high refresh rate.

I mean, you never _need_ a super-high refresh rate. But after having a 120hz screen on my work MBP for a couple of years, I definitely _want_ it; it's the main reason I've held off on getting a personal MBA, in the hope that it trickles down.

Macbook Pros have full range VRR (1-120hz) though, which not only reduces power usage compared to 120hz at all times but can bring it below that of 60hz at all times, depending on what you’re doing — for example if you’re just reading or typing or watching 24FPS TV/movies, the total number of frames drawn on a ProMotion capable MacBook is way lower than on its 60hz-locked counterparts doing the same thing.

This costs extra to implement though so you don’t see it too often in Windows laptops except sometimes in gaming laptops.

Ah, right; tbh I thought all high-freq displays supported this these days.
