You'd need like a 6k display to even start getting close to the 1920x1024 at arm's length equivalence. That's at least a generation or two ahead of where we're at today. That's why all this Mixed Reality stuff coming out of Microsoft today is just so much talk.
I'm not arguing against them working on it, there should be a foundation but we're currently at the equivalent of the late-90s, early 2000s VR devices when it comes to HoloLens and AR.
