If you are purchasing a 4k TV for gaming purpose, make sure to ascertain the input lag and refresh rate. The lower the input lag, the more quickly will the image transfer from the game console of the screen. A refresh rate signifies how often aTV changes images on the screen meaning frames per second. An optimum refresh rate of 60 kHz, i.e., 60 frames per second will not make a TV display look fake.
