This is not true, for LCD computer monitors at least, and I can't think of any reason it would be different for LCD televisions. Most LCD computer monitors have been demonstrated to actually have video processing lag - there is a lag between the time an image is produced by the source (e.g. the video card in your computer) and displayed on the LCD screen. There is no such lag with CRTs.
See here for examples: http://www.behardware.com/articles/6...-3rd-wave.html
Here's an excerpt:
If you didn't already know, almost all LCD monitors have a small delay in display. To measure this, we photograph a chronometer which is precise to 1/1000th of a second displayed in clone mode on our reference CRT and the LCD we are testing. We take 12 consecutive differences, eliminating the two extremes and then find the average delay. The most reactive model measured up until now is the 22 inch Iiyama ProLite E2201W, which had no delay on our 12 measurements. Normally, we find a delay between 10 and 30 ms on most screens.
10-30 ms delay, for a source refreshing at 60 frames per second, amounts to a 1-2 frame delay. I've seen other LCD reviews where they actually display a frame counter in a game on both a CRT and an LCD, and photos show that the LCD display is several frames behind the CRT.
This fact does not get nearly as much attention as it should. In action games where reaction time is critical, e.g. first person shooters, if your reactions are a few frames behind your opponents it can easily be the difference between fragging or being fragged.
