This is an interesting suggestion. Like with most suggestions here, I have no idea if it would work or not, so I'm making a list of things to try.
One thing that would concern me a bit with this though is how I'd use my neck. To give an example, when sitting in front of my screen now, if I want to see the browser tabs at the top of my screen, then I have to tilt my head backwards to see them. But if I need to see the taskbar, I have to tilt my head down. It doesn't sound like much, but doing that all day rather than just moving your eyes instead adds to overall fatigue.
With your suggestion, I can't picture if that would still be required or not. Thanks for sharing the idea. I'll look into it.
I don't know if this will help you visualize it or not, but here's a photo of someone using a TV as a monitor on a desk

I use my 4K TV as a monitor (though from ~8ft away) and for me Windows' scaling (found under Display in Control Panel) allow me to easily read text from so far away
Maybe it could help you
