Vizio tv question on fast response feature

brief background of my set up im using a 1080p 37 inch Vizio tv as my monitor, today i was looking at the settings and noticed when i go into more options theirs something called fast response? and i can turn it on or off. i looked it up online and cant find what it does it seems like only vizio tvs have it or something im not sure. basically just wondering if i should have it on or not? and maybe someone here knows what it is. thanks
