Thank you for posting on the HP Support Community.


Use the following steps to see if a built-in on-screen message is displayed.

  1. Connect the video cable and turn on the computer.

  2. Turn on the display and wait about ten seconds while the computer starts.

  3. While the computer is starting, disconnect the video cable. What happens?

    • If a message is displayed, the display panel is working and the problem is related to the video signal. For further troubleshooting steps, see HP support document, Flat Panel Monitor Displays Message about No Signal, Signal out of Range, Sleep, or Power Save.

    • If the display remains blank, turn off the computer and continue troubleshooting.

    • Some displays do not have on-screen messages but instead use the lights to indicate no signal. When you disconnect the cable, instead of an on-screen message, the light turns amber, indicating that the display lost signal and is working properly, but is out of range, or not receiving the signal.

Hope this helps! Keep me posted for further assistance.
