Gamers must navigate a delicate cycle every time they are in play mode: the fragile feedback loop between your game controller, your brain, your fingers and the action on the TV screen. The thrilling immediacy and gaming performance of the playing experience can be diminished by any delay. In some games, that delay to respond to your reactions can get your character killed.
With online games at least, the biggest source of those delays is latency between your console and servers on the internet, which is largely out of your control. But another source of lag, for all types of games, is introduced by the TV itself.
