Refer to the operating instructions provided with the computer for additional model specific information. Manuals are posted on your model support page.

  3. Reset the computers BIOS to the default values.
  4. Connect the monitor to a different computer.

    NOTES:

    • If the issue does not occur when the monitor is connected to a different computer, the problem is with the software configuration, video card, or other hardware of the originally connected computer.
    • If the monitor continues to display the No Input Signal message, the issue is either with the monitor or the monitor connecting cable and service may be required.
