Use this key to activate automatic setup and adjust menu.
The following dialog appears on a black screen as the monitor
self-adjusts to the current input:
Auto Adjustment allows the monitor to self-adjust to the
incoming video signal. After using Auto Adjustment, you can
further tune your monitor by using the Pixel Clock (Coarse) and
Phase (Fine) controls under Display.
NOTE: Auto Adjust does not occur if you press the button while
there are no active video input signals or attached cables.
This option is only available when you are using the analog
