A:Answer Alice - The numbers 720, 1080, and 2160 are often referred to as the class of the television. The higher the number, the higher the definition and the better the quality of the picture, especially as you look at larger screen TVs. This is maybe an over-simplification, but basically it comes down to how big a screen you want and how much you want to pay vs how crisp the picture is. Go to Best Buy and look at the screens with an eye on the various levels of definition at the distance from which you typically watch. Good luck!
