Earlier quoted context omitted.
Even 50hz is fine. I'd go so far as to say, barring any medical or sensitivity issue, if any person prioritizes a 120hz screen they are a victim to habit or marketing. It adds zero value to the experience, and you're just looking for things to be annoyed by / brag about. Modern displays are already cutting edge. They have improved in every way that's meaningful in the last 35 years. Refresh rate is just not meaningfu…
"Even 4gb of memory is fine", "even 720p is fine", "even 2ghz CPU is fine", "even a membrane keyboard is fine", "even USB 2.0 is fine", "even 2 hours battery life is fine"... Yeah it's all "fine". If these were the specs of the only laptop available to me then yeah it would be "fine". I could get things done. One or more of those things are deal-breakers for an awful lot of people. For me, a rubbish display is a deal…
Functional: - battery life - screen resolution (binary, 2k for laptops), brightness (binary: works in the sun or not), viewing angles (binary: good enough vs not), color (binary, good enough vs not) etc - connectivity options - ram - build quality etc etc
Aesthetic: - color - finish - refresh rate - OS theming, animations and all that - material
When you say "why won't they do 120hz?" I hear "Why won't they release a magenta colored device". That's fundamentally different than "why won't they add usb c"
I don't think there's any value in 120hz. Nearly all content I consume is in 30-60 fps anyway. I don't need to see marginally smoother os animatations lol and thats nearly all 120hz is good for.
PS Gamers might actually functionally need high refresh rates. I'm not in that space, but I recognise that for some specializations it might be absolutely deal-breaker.
