Not to be pedantic, but everyone seems to blaming input lag solely upon the monitor/tv.
There are many factors that contribute to input lag, however display lag rightly deserves to be labelled the main culprit.
The reason for this is that the majority of TV's are developed primarily for TV viewing, not gaming. From the manufacturers point of view what difference would it make to a viewers experience if the time between the TV receiving the signal and displaying the signal is delayed, the answer, none what so ever.
Obviously when it comes to gaming, this is clearly a big issue, which manufacturers have been addressing over the last few years.
The trouble is essentially two fold, processing time & response time.
The first issue was easily addressed by simply incorporating a gaming mode on the TV, which basically bypassed the image processing of the TV (i.e. as soon as the TV receives the signal it displays it)
The second issue was a much more difficult problem. CRT TV's have a almost instantaneous response time as do plasma TV's this is mainly due to reaction times of gas when stimulated by electrical signals.
LCD, LED LCD & TFT LCD meanwhile, all share the same problem in that the response time is dictated by the speed at which the Liquid Crystal molecules can twist when stimulated by electrical signals.
This unfortunately is the major cause of display lag, and while avoidable, as LCD, LED LCD & TFT LCD can achieve fast enough response times, it is generally over looked by many potential customers when looking at a long list of features particularly when it can lead to a potentially more expensive TV.
I was fortunately enough to buy a 42" Pioneer plasma 5 years ago which allowed me to avoid the above issued which I'm very glad of :)
