Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?
• Have you tried any troubleshooting steps?

While you respond to that, let's try these steps: 

• Step 1: Check the power
• Step 2: Check for fan noises, beeps, and power lights
• Step 3: Reset the monitor
• Step 4: Check for error messages on the monitor
• Step 5: Check cable connections
• Step 6: Connect the computer to another monitor
