There doesn't seem to be that much difference between a good general-purpose VR headset and a good gaming-focussed one though. The refresh rate, positioning accuracy, latency and so on have to hit a certain high standard or you simply have a bad, non-immersive and likely sickness-inducing VR headset. (So the situation is very different from monitors: 60Hz and high latency is "good enough" for general-purpose monitor use but poor for competitive gaming.) If anything non-gaming applications may be more demanding when it comes to resolution: games can manage with 1080p but it's not really sufficient for reading text, viewing photos and so on.
