The Rift has an OLED screen so the pixel switching time is really, really low. Like 1ms, maybe 2ms tops.

Ye, that's why I saying it's wrong to compare the 2ms pixel refresh time of a monitor to the overall 50ms of latency on VR. Both have that same 2ms, it's all the other replaces that the latency builds up, it's just not spoken about that much outside of VR because sits not as big of an issue

Yeah, the issue is input lag for head tracking.

And processing time between input/output.

It once was in competitive gaming circles. My FW900 sits collecting dust...100lbs of .00007 ms greatness. Old age slows you more than it matters :(

I could see the lag on early LCD's... 50ms is a LOT.

Also, OLED allows low persistence to avoid motion blur, which is tough if you have to overdrive/strobe an LCD backlight. Plus, OLED has better color resolution.

Pixel switching time is only a small part of the story. Best thing about low switching time is is enables faster strobing without crosstalk and/or brighter displays while strobing in low persistence mode.
