HP Spectre with external display

[Didi6211]

I have connected my Spectre laptop through a HP Docking station to a LG display. The LG display goes blank every 5 to 10 minutes. Can anyone  help to locate the root cause?

Hi @Didi6211, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Since your LG external display is going blank every 5 to 10 minutes while connected to your HP Spectre x360 14-ea1000 through an HP Docking Station, here are some troubleshooting steps to locate the root cause:

Check Physical Connections

• Secure all cables: Ensure the dock’s power adapter is firmly connected and all USB-C, HDMI, or DisplayPort cables are seated properly.
• Try a different port: If your docking station has multiple display output ports, switch to another one.
• Test another cable: A faulty HDMI/DisplayPort cable could be the issue.

Update Graphics & Dock Drivers

• Update Intel Graphics Driver
  • Download and install the latest Intel Iris Xe Graphics driver from the Intel website or HP Support Assistant.
• Update Docking Station Firmware & Drivers
  • Check for updates via HP Support Assistant or from the official HP website for your specific docking station model.
• Windows Update
  • Go to Settings > Windows Update and install the latest updates.

Check Power & Sleep Settings

• Disable USB Power Saving:
  • Open Device Manager > Universal Serial Bus controllers
  • Right-click each USB Root Hub > Properties > Power Management
  • Uncheck “Allow the computer to turn off this device to save power”
• Disable Display Sleep & Power Saving Mode
  • Go to Settings > System > Power & Sleep
  • Set “Turn off display” to Never (or a long duration).
• Check LG Monitor Power-Saving Mode:
  • In your LG monitor settings (using the on-screen menu), disable Automatic Power Save or Energy Saving Mode.

Test Direct Connection (Bypass Dock)

• Connect your Spectre directly to the LG display via HDMI or USB-C (without the docking station).
  • If the issue persists, your LG monitor or Spectre GPU may be the cause.
  • If the issue is resolved, the dock might be faulty or needs a firmware update.

Check Event Viewer for Errors

If the screen goes blank at specific intervals, check Windows logs:

• Press Win + X > Event Viewer > Windows Logs > System
• Look for critical errors or warnings around the time of display blackouts.

Test with Another Display

• If possible, try connecting a different monitor or TV to the docking station.
• If the new display works fine, the LG monitor may be the problem.

If the issue is with the dock → Update firmware or replace it.
If the issue is with the LG monitor → Adjust its power settings or try a factory reset.
If the issue is with the Spectre laptop → Perform a clean driver reinstall or consider a Windows update/rollback.
 

I hope this helps. 

Take care and have a good day.
