I have an HP computer and Monitor and sometimes the monitor works and sometimes it doesn't.  Computer put in sleep mode and monitor goes black like it should but on trying to wake up the system monitor stays in sleep mode.   Restart  computer, computer is up but no display on monitor.   Multiple reboots and then the monitor  is up.

Hi @ffllmm,

 

Welcome to the HP Support Community. 

 

I'd be glad to help you! 

 

That sounds incredibly frustrating, especially when you're trying to get work done and your monitor won't respond as it should.

 

Use these steps to troubleshoot your blank monitor or to determine if the monitor is defective.

 

Note: Before you begin, make sure that you perform the following steps:

  • Turn off the computer.
  • Disconnect all connected devices from the computer, except the mouse and keyboard, including USB flash drives and memory cards.
  • Make sure that you have a second monitor cable if your monitor has a detachable cable for testing purposes.

Check the power

  • To check the power, disconnect the video cable from the monitor and make sure that the monitor power cable is plugged into an AC outlet.
  • When you press the power button on the monitor, the power light turns on. If the power light remains off, the monitor is not receiving power or the monitor is defective.
  • Check the following items before attempting to service or replace the monitor:
  • Make sure that the AC outlet has power and the AC outlet matches the power rating for the monitor.
  • Connect the monitor to a different AC outlet.
  • Try a different HP power cord.
  • If the light is on, the monitor has power, and you can continue to the next step. Click here

 

Hope this helps! Keep me posted for further assistance
