what are typical data refresh rates
A monitor's refresh rate, or vertical scan rate, is the number of times in a second a monitor redraws a picture. Refresh rate is not the same as frame rate, an attribute that concerns many video game players and some movie viewers. Frame rate measures how many times per second the source image changes. Refresh rate is how many times per second the monitor redraws the image. A monitor will redraw an image at the same rate no matter what the frame rate of the game, movie, video, or other source.
