VR headsets are 1440p LCD screens that are optically projected to about 2 meters from your face. Furthermore, since they're flat screens, angular pixel density decreases in the periphery. http://doc-ok.org/?p=1677 has some good discussion on how it works.

As such, if you can imagine a giant 1440p screen 2 meters from you (or if you have a projector), that's what you're going to get. Some headsets like the odyssey+ have a diffuser so the pixels are blurred together, but it's still a limited amount of information displayed, compared to a 1440p monitor 50cm from your face.
