I'm sorry my dad was the one who filled this out and didn't consult me on the question as he doesn't know too much when it comes to gaming. The real problem I'm having with my new LED HDTV is not screen lag, it's button lag on my wireless 360 controller whenever I press a button it doesn't react until I have the button fully pressed whereas it should be reacting as I'm pressing my guess is like a .5 second lag time. For an example it's like your brain knows what arm to move but your arm doesn't move until it recieves the message to move. I've already tried adjusting the pixels (currently using 720p) and trumotion was turned off from the beginning so that can't be it. I've also tried using an xbox original console and got the same result (used a wired controller). Also one final piece of information my t.v. is also a smart t.v. I'm not sure if that would effect anything or not though. That's about all I have please tell what you think and if the same solution would still fix it or if something diferent is required.
