Solved Slight lag on extended desktop

I just purchased a brand new Sharp HD Smart TV and have been using it occasionally as an extended/dual desktop from my laptop. The only thing is that there is a very slight delay between the input from the computer and the display on the TV. I don't know if this is normal or not as the delay is only a split-second but I want to use it for gaming purposes so I want to get rid of the delay if at all possible. The spec on my computer are as follows:

Windows 8 Pro
Intel Core i7-4800MQ CPU @ 2.7GHz
32 GB RAM
GeForce GTX 780M graphics card

If anyone has any tips I would aprecciate it. Thanks

It turns out there is a "Game Mode" setting on the TV that eliminates the lag.
