It still doesn't sound right...that doesnt sound rightmost led TVs have a 1 sec lag when playing games
I think you mean 5ms refresh rate
This is actually somewhat true... Many HD tvs have image enhancing filters applied to them, which takes a while to process and isn't noticeable in movies.. however, when playing, it is!
That's the 1 second lag, image enhancer... However, those tv's most often have something called "gaming mode" in the menus... look for it, it will speed things up

You guys are underestimating how long is 1sec. It's pretty damn long, when it comes to lag/refresh rate.
I don't underestimate how long 1 sec is, however, I am thinking that the 1 sec explanation is an exaggeration...
So, if the TV in the OP is a samsung at least, it DOES have lag!! It's an image enhancer, (Not the upscaler or anything, a straight forward enhancer, making it look "better"). It can be turned off by turning on the Game Mode. Game mode disables the enhancer, and just put the game on.
The enhancer is meant for movies and television, not gaming.
