Thank you for posting on HP Support Community.


Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

  • Did you check with an alternate cable or another monitor to verify the issue?

While you respond to that, here's what you need to know:

The message - "No Input Signal" is normal when the computer truly goes into sleep mode or loses the video signal (such as when the computer is turned off). However, if the monitor displays any of these messages when the computer should be displaying video, something is wrong. 


Check with an alternate video cable (HDMI or VGA) 


If the issue persists, try the below steps: 

The display's resolution used by Windows has probably been set to a resolution that cannot be used by the monitor. Use the following steps to see if the monitor can display screens from safe mode: 

  1. Cycle the power on the monitor as follows: 

    1. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on. 

    2. Unplug the power cord. 

    3. Wait 5 seconds. 

    4. Plug in the power cord. 

    5. Press the power button on the monitor to turn on the monitor. 

      One of two things happens: 

      • The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode on the computer. For some computers, updating the BIOS can correct these types of suspending problems. 


      • The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps. 

  2. If the computer is on, wait until the hard drive activity light on the computer is not lit and then press and hold the Power button on the computer case until the computer turns off. 

  3. If the monitor has a factory reset or restores options, set it. Press the Menu button on the front panel and select Factory Reset. 

  4. Wait 5 seconds and then turn on the computer by pressing the Power button again. 

  5. Adjust the Windows display resolution to a setting that is compatible with the monitor.
