Why must a UI use the same font on low DPI displays as on high DPI displays?

I don't want the font to change just because I moved a window from my high DPI laptop display to my external low DPI display.

Most people place functionality over design, but there is no reason why you can't have it your way. Just make the fonts configurable. Your usecase isn't very common so I wouldn't make _that_ the default choice, though.

My use-case isn't very common? Apple has been selling laptops with high DPI screens since 2012, and over in the PC land, many laptops that aren’t cheapo garbage ship with screens that run at 125% or 150% scale. On the other hand, many external displays run at 100% scale, or otherwise at a different scale than the primary screen.

Ok, in the Apple world choosing design over functionality is quite normal, I guess. Maybe things should work differently there. I don't know because I don't use Apple hardware and actually try to avoid it.

Anyway, I don't think that changing fonts on different displays is really a problem. If you're reading a book and a magazine, then switching between the two will also cause the fonts which you see to switch, and it's not like your brain has any trouble with it. Basically, your brain can quickly and easily get comfortable with the idea of looking at A and seeing font 1, and looking at B and seeing font 2.

		I went to dell.com, looked at laptops, and the first laptop they showed me [0] has this: `16" 2.5K (2560 x 1600) Anti-Glare Non-Touch 300nits WVA/IPS Display with ComfortView Plus` This is absolutely unusable at 100% scale. Windows probably defaults to something between 150% and 200%, and probably on the further end of the scale. And if you don’t want crisp fonts, the alternative [1] is: `16.0-inch 16:10 FHD+ (1920x1200) Touch 300nits WVA/IPS Display with ComfortView` Windows defaults to 125% scale on screens like this. 100% is not comfortable at typical viewing distances.

I think it's very common to have a large 1080p screen as a second monitor (projectors and TVs).

When pixels are that big, the readability of a good font allows you to actually use the extra space instead of just making everything huge.
