What do you mean? I don't think tvs have input lag. You mean like the delay you calibrate for when you're playing Rock Band?

Some have real problems with latency, it's especially evident in some plasma displays. However, it's not really the input that is lagging, but actually the video that the player sees on-screen.

Right, that's kinda what I was gettin at.
 
I don't know of any ways to determine what your TVs delay is. Maybe get a RB 2 guitar and do the auto-calibrate thing and see how many milliseconds it has to offset by.

I dont know to much about this stuff guys but I have been reading on Mlgpro.com and people were talking about making sure to buy a TV without alot of lag. I was pretty sure it was called input lag but I could be wrong. It might be refresh rate but I'm not sure. I guess I should learn more before I ask a question lol.

Usually the way people do it is hook a PC up to whatever display you want to test and a CRT.  Then you get some timing software that will show fractions of a second nice and big, then you take a photo of both screens and count the difference.
 
LCDs, plasmas, DLP, or basically anything but CRTs often have display lag, but it's usually pretty insignificant overall.
