There is no need to use the AppleVision Recovery software as this functionality is built into the current version of the Apple Display Software. (Apple Display Software supercedes and replaces AppleVision software as of version 1.5.3.) The Apple Display software automatically looks for a no video condition at which point it will perform the same function as the AppleVision Recovery software and implement new monitor values for the CRT Video Board.
There is a keyboard combination which will also allow you to run the AppleVision Recovery sequence if you encounter a no video condition after a color recalibration of the display. In order to perform this function you will need to restart the computer and after the first extension loads hold down the Command, Option, A, and V keys until you here a beep tone or when the video is restored to your display.
