ahh, so the distance between the left edges of the lines in the the two vertically stacked screens indicates the relative difference in input lag. Got it :)

glad you figured it out; I'm not that great explaining this stuff in words :P
If anyone else wants to understand, I can draw some figures that should make it clear.

just tested my old viewsonic lcd and my laptop's (thinkpad x220) ips lcd against my fw900

the viewsonic seems to have about as much input lag as my vg248qe. :?: :?: :?:
laptop... well the pixel transition time is ridiculously long so the gradient was very very faint, but it also doesn't have much input lag (<5ms) as far as signal processing is concerned.

I expected quite a lot more input lag... e.g. http://www.tftcentral.co.uk/images/asus ... 8q/lag.png
did i get lucky with my viewsonic and my laptop, or is my method fundamentally flawed

this viewsonic isn't even anything special. just some $130 thing from 2009...
