1920x1080 and 24 inches
Maybe the issue is not scaling according to DPI?
OTOH, people with 30+ inch screens probably sit a bit further away to be able to see everything without moving their head so it makes sense that even sites which take DPI into account use larger fonts because it's not really about how large something is physically on the screen but about the angular size relative to the eye.
Yeah, one of the other cousin comments mentions 36 inches away. I don't think they realize just how far outliers they are. Of course you have to make everything huge when your screen is so much further away than normal.
