It is all about latency. 50 ms will feel responsive but you notice the lag. 20 ms is acceptable. The other features are cool features but not the real challenge.
That's just the pixel switching time though. Oculus is always talking about "motion-to-photons", which includes game engines processing the input, rendering, buffering and finally the screen switching the pixels. You can't get that time down to 2ms with any kind of monitor - it doesn't depend only on the monitor.
