Input lag occurs in every TV. Lag is the time difference between a signal input (on your controller) and the time is takes to manifest this on screen.

So make sure you got your HDTV set on Game mode when playing on console. This mode improves latency between input and picture by disabling certain image processing protocols. In short, Game mode cuts down the response time on the video feed.

But by doing this the picture quality will suffer; color processing, noise reduction, advanced scaling and such are bypassed or greatly reduced, meaning the picture will look less pretty. Still, the less your TV has to work, the more responsive your controller is.

Game mode is available on most current TVs, e.g. Samsung, LG, JVC, Panasonic, Sony, Philips, Sharp.

There’s an input lag database online you might like to check out.
