How many people are affected by input lag? Do people get used to it and are able to compensate for it? Do laptops and netbooks have this problem? Is there any way to tell how much input lag a monitor has before buying it? Does it really make first person shooter games unplayable?

NEC Display Service & Support just told me majority of the lag depends on the video card. Is this true?

Not at all.

Input lag isn't a huge issue unless it is fairly large (>30ms or so). It's definitely a feature of the monitor though, not one of the video card. Most laptops should have minimal input lag, since their monitor does not do any significant processing of the signal.

Oh, and it doesn't make first person shooters unplayable at all. It makes them more difficult if it is extremely high.

Is the average monitor under 30ms? How about hdtvs and large format displays?

Anything and everything can cause input lag. Read the following article:

I would say average is probably around low 20's for PC monitors as a whole. There will be faster and there will be slower. These are based on test done on some monitors.

HDTV's and large format display? Only testing can tell...

How many people are affected by input lag?
Everyone. Whether they notice it or not.

Do people get used to it and are able to compensate for it?
Yes, people can whether consciously or subconsciously, but not everyone will. Depends on how sensitive you are to such things.

Do laptops and netbooks have this problem?
Yes, everything.

Is there any way to tell how much input lag a monitor has before buying it?
Only if a review of the monitor includes such tests.

Does it really make first person shooter games unplayable?
For the average hardcore gamer, no or very few will complain to a large degree. If you are a dedicate competitive gamer (meaning it is basically your living), then I would have to say yes because any lag at all can mean elimination from the tournament which means you walk away will very little prize money, if any. To be a competitive play you need very fast reflexes (which in itself is a form of input lag), more than just the mere hardcore gamer.
