Yes, human visual perception exists along a spectrum of temporal, spatial, and chromatic resolution that varies from person to person — I’ve even met some people who can’t perceive the difference between 30hz and 120hz, while to me and most people I know, the difference between 60hz and 120hz is enormous.

So you could make the same argument against high DPI displays, superior peak screen brightness, enormously better contrast ratio, color gamut, etc. Also speaker quality, keyboard quality, trackpad quality, etc.

Where does this argument end? Do you propose we regress to 60hz 1080p displays with brightness, contrast, and viewing angles that are abysmal by modern standards? Or is the claim that the MacBook Air’s current screen is the perfect “sweet spot” beyond which >99% of people can’t tell the difference?

I think the market data alone disproves this pretty conclusively. Clearly a significant enough percentage of the population cares enough about image quality to vote with their wallets so much so that enormous hardware industries continue to invest billions towards make any incremental progress in advancing the technology here.

To be fair, I think there’s strong data to support that modern “retina”-grade DPI is good enough for >99% of people. And you can argue that XDR/HDR is not applicable/useful for coding or other tasks outside of photo/video viewing/editing (though for the latter it is enormously noticeable and not even remotely approaching human visual limits yet). But there’s plenty of people who find refresh rate differences extremely noticeable (usually up to at least 120hz), and I think almost anyone can easily notice moderate differences in contrast ratio and max brightness in a brightly lit room.

Lol, reminds me of audiophile discussions when most people listen to youtube streaming a recompressed version of an mp3 someone uploaded.

It’s not imagined though, I use my partner’s phone sometimes and every time I used it I thought it was broken because the UI jitter was so jarring at 60Hz. Actually I’m still not convinced her phone isn’t broken. Also her flashlight resets to the lowest brightness EVERY time it’s cycled.

It’s deeply flawed logic at best (or an intentional red herring at worst) to cite the existence of pseudoscience discussed elsewhere, as an argument against real science being discussed here.

There is a well-understood science to both auditory and visual perception, even more concretely so for the visual side. The scientific literature on human perception in both categories is actively used in the engineering of almost every modern (audible/visual) device you use every day (both in hardware design, and software such as the design of lossy compression algorithms). We have very precise scientific understanding of the limits (and individual variation) of human visual and (to a slightly lesser extent) auditory perception and preferences.

It continues to amaze me years later how many people happily enjoyed watching 4:3 content stretched to 16:9, before 4:3 mostly disappeared from broadcasts.
