Thanks. I've done stuff like that. For "whole system" lag it's also a good idea to record input lag with a faster camera and analyze the count the number of images/frames that it takes from the input to the output on screen.

My problem is that, from what I've seen so far, camera/capture card retailers sometimes don't and there doesn't seem to be a particular standard for those who do.

Thanks for the link. It's quite interesting.
