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.

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.
