I have a LG50PM680T, and to be frank the input lag on the xbox is insane, even in game mode. It's so bad it also has out of sync sound, but so does every other channel. Im sick to the teeth of having to keep re adjusting the audio sync in the settings. I'd go as far to say as this TV is useless. So on that note I'm looking for a new TV, must have low input lag, and 47 - 50 inch. Any suggestions? Not fussed about 3D either.
