I've currently got 4 monitors on my workstation, but I still want more desktop space. Is there a head-tracking VR headset (either augmented reality or such that a keyboard can still be seen/used while wearing) that could be used as a 360-degree (or even 180 degree) monitor? What kind of virtual resolution would I end up with? Is it wireless?

(I realize that it would probably be unpleasant to turn around and use desktop space behind me, but I would at least be able to maximize the use of my field of vision).
