Nice charts, did you draw them by hand? You are right. That directly contributes to latency. This effect is called pixel response time [1], and is usually measured "grey-to-grey" [2]. Nowadays, though, I think monitors usually have a short response time (<1ms for "gamer" monitors). > Persistence is the time it takes between when the luminosity goes up and when it goes down Right. But that proves the two are somewhat linked, especially as pixel response isn't symmetric (0->1 and 1->0). Reading a bit more into it, the industry terms for persistence seem to be both grey-to-grey (GtG), and Moving Picture Response Time (MPRT). The latter is a measurement method [3] for perceived motion blur. It directly depends on the time each pixel remains lit with the same value ("persistence" strikes again), so a slow (>1 frame) or incomplete transition can create motion blur (contributes to persistence). > low persistence is emulated with a high refresh rate and black frame insertion It can also be achieved wit backlight strobing on backlit displays: strobing for 1ms on a "full-persistence" (pixel always on) display gives a 1ms persistence regardless of the frame rate. A ~1000 FPS display would be necessary to get the same level of persistence with black frame insertion alone. I believe this is part of the reason Valve went with an LCD instead of an OLED screen to get the 0.33ms persistence on the Index HMD.
