Hi @Carol04,

Welcome to the HP Support Community! We're stoked to have you on board! 

To help us get started on resolving your issue, could you please share the model name of your device?

Meanwhile, you can try these steps:

Check Power and Connection

Power Supply:

• Ensure the monitor is properly powered.
• Check if the power cable is securely connected both to the monitor and the power outlet.
• Try plugging the monitor into a different power outlet.

Connection to PC:

• Verify that the video cable (HDMI, DisplayPort, VGA, etc.) is securely connected to both your monitor and your PC.
• Try using a different video cable or port on your computer to see if that resolves the issue.

Adjust Power Settings

Power Settings in Windows:

• Right-click on the Start Menu and select Power Options.
• Ensure that the power plan is set to High Performance.
• Click on Change plan settings for the selected power plan, then select Change advanced power settings.
• Under the Sleep section, set the Sleep after to Never.

Monitor Sleep Settings:

• Check your monitor’s on-screen settings to ensure sleep mode is appropriately configured.
• Look for options like Sleep or Eco Mode and disable them if necessary.

Monitor Reset

1. Reset Monitor:
   • Turn off the monitor and unplug it from the power source.
   • Wait for a few minutes, then plug the monitor back in and turn it on.
   • Check if the issue persists.

Graphics Card and Driver Update

Update Graphics Driver:

• Open Device Manager by right-clicking on the Start Menu and selecting Device Manager.
• Expand the Display adapters category.
• Right-click on your graphics card and select Update driver.
• Choose Search automatically for updated driver software.

Check Graphics Card:

• Ensure your graphics card is properly seated in its slot (if you’re using a desktop PC).
• If possible, try connecting the monitor to a different computer to determine if the issue is with the monitor or the graphics card.

I hope this helps.
