I was reading an article on the new LG display with a refresh rate of 7680Hz and it says:

While a typical refresh rate for a monitor might be 60Hz-240Hz, an outdoor display designed to be viewed from a distance needs to be much higher

The idea that there’s an intrinsic link between refresh rate and viewing distance is new to me and feels unintuitive. I can understand the need for high brighteness for far view distance. I also could understand refresh rate mattering for a non-persistent (CRT) display. But for an Led display surely you can see it far away even if it refreshes once a second?

Refresh rate normally needs to be high enough to avoid pixels “jumping” between refreshes on high resolution displays, so wouldn’t higher view distances allow you to decrease the refresh rate?

Is the article just spouting bullshit? Or is there an actual link between refresh rate and view distance?

    If you google something like ‘7680hz led’, you’ll find many results of products and such. 7680 is a multiple of 20, 24, 30, 60, among others, which are all common frame speeds for video files, but also for recording video. I also found this video, which shows the difference of large size screens with different refresh rates: https://www.youtube.com/watch?v=JP6fHWcUifo
