A:Answer I can attest to this, I just tried playing my xbox one on this tv before finding where game mode was in the menu to turn on, the input lag was horrible, instead of the game doing the action as soon as I taped the button the action wouldn't happen until the button was fully pressed, after finding game mode there was no input lag, I don't think game mode took away from the picture quality but it definitely took away from the brightness of the picture
