in windows media player we are getting visualization while playing music.... if we are in small screen(i mean not in full screen) its not nice to see... lacking in resolution.... how does it give absolute perfection when its viewed in full screen even if the monitor changes.... doesn't it hav anythin to do with the resolution??

The visualizations are computed in real time, which makes them scalable, in theory, to any resolution. Compare them with a video file: it is composed of a bitmap, a "table" of pixels for every frame and it is best viewed at a certain resolution. A video file will also have a fixed frame rate, because each frame must be made in advance and stored in the file. The visualization is like a vector graphic, the maker of the program has decided on an algorithm to generate the fancy effects according to the music. The computer then uses this algorithm to draw visualizations on the screen. This is the way most games handle drawing graphics, but since they use textures (which are usually of fixed detail, like video files), they have limits for detail.
