I think phone OSes just do DPI scaling better, because they've always had to deal with highly heterogeneous physical screen sizes. Desktops were firmly in 96DPI

I think phone OSes just do DPI scaling better, because they've always had to deal with highly heterogeneous physical screen sizes. Desktops were firmly in 96DPI land for quite a while. I'd wager that if your screen pixels are "too small for comfort" you or your graphics setup hasn't gotten scaling right yet.
