Hi @MrP76,

Thanks for sharing the details. 

When your HP Laptop Model No 14s-dq1505sa stops recognizing a connected monitor via HDMI after going into standby mode or restarting, it could be due to several reasons such as software updates, driver issues, or power settings. Here are some troubleshooting steps you can follow to resolve the issue:

Basic Troubleshooting

Check Connections:

• Ensure the HDMI cable is securely connected to both the laptop and the monitor.
• Try using a different HDMI cable to rule out a faulty cable.

Restart Both Devices:

• Restart your laptop and monitor. Sometimes a simple restart can fix connectivity issues.

Check Display Settings:

• Right-click on the desktop and select "Display settings."
• Ensure that the monitor is detected. If not, click "Detect" to search for the monitor.
• Verify that the display mode is set to "Extend" or "Duplicate" as desired.

Advanced Troubleshooting

Update Graphics Drivers:

• Open Device Manager by pressing Win + X and selecting "Device Manager."
• Expand the "Display adapters" section.
• Right-click on your graphics driver and select "Update driver."
• Choose "Search automatically for updated driver software" and follow the prompts.

Reinstall Graphics Drivers:

• If updating the drivers doesn't work, you can try reinstalling them.
• In Device Manager, right-click on the graphics driver and select "Uninstall device."
• Restart your laptop, which should automatically reinstall the driver.

Adjust Power Settings:

• Open Control Panel and go to "Power Options."
• Click on "Change plan settings" next to your selected power plan.
• Click on "Change advanced power settings."
• Expand the "PCI Express" section and then "Link State Power Management."
• Set both "On battery" and "Plugged in" to "Off."

Please find the next set of steps below.

Monitor-Specific Settings

1. Check Monitor Settings:
   • Use the monitor's on-screen display (OSD) menu to ensure the correct input source (HDMI) is selected.
   • Reset the monitor settings to factory defaults if necessary.

Further Steps

BIOS/UEFI Update:

• Visit the HP support website and check for any BIOS/UEFI updates for your laptop model.

Try a Different Monitor:

• If possible, connect your laptop to a different monitor or TV to see if the issue persists. This can help determine if the problem is with the laptop or the monitor.

If the issue continues after trying these steps, there might be a hardware issue with the HDMI port on your laptop or the monitor. In that case, contacting HP phone support for further assistance or repair might be necessary.
