Frame rate matching. Movies are generally created at 24 frames per second or thereabouts. Modern TVs are usually 60 frames per second or higher. The TV has a function that can translate the 24 frames per second of the film to the frames per second of the TV panel. The quality of this translation varies with different TV models. The film will look best when the TV can switch to a 24 frames per second mode. This will remove the Soap Opera effect that you may be experiencing. Look for any Motion Smoothing options in your TV settings and turn them off.
