See, this is what I don't get either. My 7603 does NOT have a Game mode at all. How come yours has this Game mode whereas other people don't have it on the 7603? Believe me, I have tried everything possible with this set to get rid of the horrendous (And yes it IS horrendous) input lag, and nothing at all works. This set does not have a dedicated game mode at all.
Well my 7603 does not have game mode either.
Wu Xian Are you sure you have 7603 ?
