Message: <blockquote data-quote="counter dr" data-source="post: 16348553" data-attributes="member: 385781">The refresh rate (most commonly the "vertical refresh rate", "vertical scan rate" for CRTs) is the number of times in a second that a display hardware updates its buffer. This is distinct from the measure of frame rate  in that the refresh rate includes the repeated drawing of identical  frames, while frame rate measures how often a video source can feed an  entire frame of new data to a display. For example, most movie projectors  advance from one frame to the next one 24 times each second. But each  frame is illuminated two or three times before the next frame is  projected using a shutter in front of its lamp. As a result, the movie  projector runs at 24 frames per second, but has a 48 or 72 Hz refresh  rate.<a href="http://en.wikipedia.org/wiki/Refresh_rate" target="_blank">http://en.wikipedia.org/wiki/Refresh_rate</a></blockquote>
