You get what you pay for! Usually on the cheaper TV's you will get a checker board effect when things start moving real fast. Watch an action movie during an explosion and you will see it. Sometimes you will see squares when it happens or the colors may even change a little bit, you will see more black than color. Also the cheaper TV's will have a slower refresh rate (which is what causes the checker board effect) and less viewing angle on the screen. And all of this is effected by the size of the TV itself. Obviously, the bigger the screen the more noticeable things are.
