To add to this: I have a Vision Pro and a 34" curved ultrawide. The latter is much more usable in this regard, because the effective resolution per degree is higher, which means you can keep your head static and use your eyes to look around.

By contrast, you have to use a giant screen on the Vision Pro to get equivalent resolution, which means you have to move your head. It still has its advantages (you can take it wherever you go, and the resolution of the virtual screen can be higher), but it's not yet comparable to a physical monitor, to my chagrin.
