Yep, input lag in an LCD monitor context is the amount of time it takes for a frame to be displayed on the screen.
A lot of panels have a varied amount of input lag. Some of them are in the single digits of milliseconds. On the other side of the spectrum you could see upwards of 100ms.
It's really bad when you get something like 30ms to 70ms of random delay. You can't predict this type of randomness and since it happens every frame it makes for a very poor gaming experience.
Think about a competitive game like quake 3 where you might be playing at a LAN where you have a 5ms ping but your monitor is giving you 30-50ms of random input lag. You would be at a -massive- disadvantage if your opponent had a monitor with 2-7ms of input lag.
There is a world of difference between 30ms and 60ms at a competitive level.
