What do you mean by the "little square"? This is a 16:9 panel so the picture should be the full panel. What is your source? If you are watching an SD tv show it has a 4:3 aspect ratio so it will either be pillar-boxed (grey or black bars on the left and right), or stretched or zoomed. I have heard that the SD content doesn't look great. Try to find an HD tv channel, or play a blu ray movie.
