Monitor goes dark inconsistently

HP Recommended
Microsoft Windows 10 (64-bit)

Noticing that the 23er monitor will go dark on me throughout the day.  Its been occurring more frequently for the past 2 weeks.  I'm connected to a Surface Pro laptop via HDMI.  The Windows 10 OS has the latest display drivers and on the latest release.  I've done some research and cannot find any specific resolution to this issue.  I have it configured to be my 2nd monitor.  I will try replacing the HDMI cable as a test (is less than a year old) as well as the converter cable from Surface to HDMI.  Any other suggestions are appreciated. Thanks.

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:

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

  • Note Before you begin: Turn off the computer.
  • And disconnect all connected devices from the computer except the mouse and keyboard. This includes removing thumb drives and camera-type memory cards.

Step 1: Checking the power

Step 2: Displaying a built-in on-screen message

Step 3: Fixing a bad video connection

Step 4: Testing the video connection

Step 4: Connecting the monitor to a different computer

Hope this helps! Keep me posted for further assistance.

Basically, it has not occurred again since yesterday. 

The monitor is an HP 23er 23-inch display. 

SN 3CM842067G ; Product #T3M76AA; built in Oct 2018.  

Please keep this ticket open for a few more days to see if it occurs again.  

Thanks, Rafael
