well mine has ZERO and is perfect for lag, or rather it has no lag when set to game mode. Which it has.Hmm many people said that this tv had 100ms lag and sometimes higher.... Really i don't know what to believe
My 7603 is just for watching TV now. Terrible to game on. Massive input lag. So bad, I couldn't play on it with games like COD4 and Rock Band etc, so bought a Samsung LE40A656 to game on, which was a huge improvement (Recently bought a Sony 32V5500 also, which I quite like).
Sorry, but I cannot recommend the 7603 to game on at all, but for watching movies etc, and standard def... the quality is awesome.
I was one of the people defending this TV for a good while, but when I started noticing just how horrible the input lag was, I couldn't defend it anymore in terms of using it to game on.
Btw, to the topic creator... have a gander at this thread. It may answer some questions you may have:
I did everything that was possible with the 7603 to eliminate lag as I didn't want to fork out for another TV just to game on, but I had no choice. The TV has horrendous lag when gaming no matter what you try on the TV mate. Btw, Wu Xian, are you sure you definitely have the 7603 model and not one of the other higher end ones?choose game mode, lag = 100% gone or at least it is for me, and im a hardcore gamer (PS3/360 user)
Maybe you had an inferior firmware?
