Quite a while ago (2005) I noticed a clear difference in my reaction time playing on a notebook display and playing on my big screen, a Dell 2001FP. I haven't heard something about LCD lag at this time. So I tried to investigate this and found a lag of about 17..20ms for that monitor. Some do lough about people complaining about the lag, but all too often it decides about life and death in FPS games. If you suddendly encounter an opponent the one with the faster reaction time will make the frag.
I created two programs to measure the lag of monitors. One is a stop watch application that writes the current time on screen but syncronously with the screen refresh (vertical sync). http://www.draebenstedt.de/reaction/timecode.zip
The time is written on screen from top down on a differnt location on screen each time to avoid blurred numbers that are continously overwritten. The second application can measure the lag by tracking a moving pattern with an optical mouse! Don't lough! It works! Please have a look: http://www.draebenstedt.de/reaction/loopback.html
