Built-in diagnostics
Your monitor has a built-in diagnostic tool that helps you determine if the screen
abnormality you are experiencing is an inherent problem with your monitor, or with
your computer and video card.
NOTE: You can run the built-in diagnostics only when the video cable is
unplugged and the monitor is in self-test mode.
