As someone who is an avid Linux user for over a decade and MacBooks daily at work, this is 100% sour grapes.

There is absolutely a visible difference between HiDPI displays and standard ones.

I mean, sure. I've got a high-dpi tablet (Surface Pro 3, GNOME 3.38, 2x scaling), and it's obviously noticeable that the tablet is higher resolution than, say, my 32-inch 1440p monitor. Honestly though, the difference is pretty minuscule in day-to-day use. I can't help but roll my eyes when I hear someone brag about the merits of hidpi when it's really just a cool novelty that reduces the number of windows I can keep onscreen at once.

I wrote *very* high DPI

You may need glasses. The difference between a 1920x1200 panel, and a 2560x1600 display at 13.3" is slight, but very visible.

I suppose if you give a generous take on what "very high DPI" is this would be easily agreeable e.g. some phones pushing 600 DPI but for the devices in question they ship with ~160 DPI displays though and that's nowhere near needing a magnifying glass to distinguish more clarity.

It does suck some power though, same with high refresh. I used to have my laptop flip between 4k 200% DPI and 1080p 100% DPI based on whether I was plugged in. Usually ran games at 1080p. Important to use nearest neighbor scaling in that situation though or it'll get blurry.

Yes, I wrote *very* high DPI but the downvote dogpile already started.
