Seeing more or having more open at once is beneficial, but so is comfort.

I bought it in 2018, but only recently I have found my 28" 4K is too small at 100% scaling. I think it is roughly the same distance away, but I'm not going to be uncomfortable, so I scale it to 125% now.

I've also found this more necessary later in the day vs when I just woke up.

Same thing ui designers. Thats why I resize all the fonts on the page. The probably negates all the UI designers attempts to make the audience go blind
