Input Source

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 Image Settings.

NOTE: Auto Adjust does not occur if you press the button while there are no active video input signals or attached cables.

Use the Input Source menu to select between different video signals that may be connected to your monitor.
