I'm in the same boat- I just want a simple headset that overlays a big, high-resolution monitor on my normal vision. The closest thing I know of is the [Simula One](https://www.simulavr.com/), which seems to be a VR "virtual monitor".

VR instead of AR is a dealbreaker for me though- I want AR virtual monitors that overlay the displays on my actual vision. Even VR which uses a camera to pass through to the display isn't really what I want.

My ideal hardware would just be a "dumb" AR display with wide FOV and an HDMI input that just overlays the video data onto my normal vision.

From what I understand a big challenge is the wide FOV though, but I don't know enough about optics to really understand why this is the case.
