Could using a LCD, delay what you see on the screen by 1/20s

A power user put his Big fat tv monitor (his CRT) next to his flat screen. You can see some delay on the LCD!

The definition of lag:
Input lag is a phenomenon associated with some types of LCD displays that refers to latency, or lag measured by the difference between the time a signal is input into a display and the time it is shown by the display. This lag time has been measured as high as 65ms, or the equivalent of 3-4 frames on a 60Hz display.

This is not the only cause of lag, for instance, network transmit times could also cause lag.

Also, this is NOT the same thing as "LCD response time" Response time measures the time for a gray pixel to turn black, which has nothing to do with the signal input into the display and the delay there. ;)
