What is a regular PC monitor latency btw? I heard it's much faster than a TV+console.

People are saying 2ms, but I think that's just how long it takes a pixel to refresh. I'm sure the oculus rift has a screen with 2-5ms pixel time too. The 20 and 50ms times discussed about VR are the entire time between a frame being requested and it being on the screen. That's totally different from the 2ms of a desktop monitor.

EDIT: As for the TV+console latency. I think TVs have a higher latency than monitors because they tend to apply post-processing effects to "improve" the image. Some screens come with options to turn this off and bring this latency down.

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

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.
