EIZO makes a 1:1 monitor you can buy off the shelf right now:
I wonder how well it works in practice. I typically have multiple tabs open so I don’t mind going wide over long. But it is easier to look down rather than sideways.
I used to have a terrible back pain that magically disappeared when I elevated my laptop so that the screen is at my eye level.
I still have a lighter version of this pain whenever I have to work for an extended period from a coffee shop or wherever I can't elevate the laptop.
