Laptop stopped sending a signal to second monitor

[Karioca95]

I've been using a second monitor since I bought this laptop and it simply stopped working - bought new HDMI cables and it continues to say that the laptop is not sending a signal to the second monitor. I've updated every driver I can find and they all they are up to date. I need this second monitor to work. The HP laptop does not detect the second monitor.

My laptop is a HP Pavillion 15 the model number is 61D22UA

I have tried three different cords as well as three different models of secondary monitors with this laptop and they don't work. I was working on a secondary monitor and it stopped working out of the blue last week. I have updated all of the graphics and  video drivers that I can find. Can you please assist?

Thanks,

Kari

Can you please let me know if you can help me? I've now tried three different monitors. I use my HP for work and work from home this is a real problem for me. 

Thanks!

Hi @Karioca95 ,

Thank you for your reply

I understand you've tried a lot of troubleshooting steps to resolve the issue with your HP Pavilion Laptop 15-eh2085cl not sending a signal to the second monitor. Given what you've done so far, 

here are additional steps you can try to pinpoint and potentially resolve the issue:

1. Check Display Settings

• Right-click on the desktop and select "Display settings".
• Scroll down and click "Detect" under "Multiple displays."
  • See if the laptop detects any external monitor, even if it's not showing up.
• If the monitor is detected but shows no signal, try adjusting the display mode:
  • Use Win + P to toggle between display modes (Duplicate, Extend, or Second screen only).

2. Check Graphics Drivers (More Thoroughly)

You mentioned updating the drivers, but to ensure thoroughness:

• Open Device Manager.
• Expand "Display adapters" and right-click on your graphics driver (you should see either AMD or Intel, depending on your configuration).
  • Select "Uninstall device" (make sure to check the box for removing the driver if available).
  • Restart your laptop and let Windows reinstall the default driver.

Alternatively, you can reinstall your graphics driver manually:

• Visit the HP support page for your laptop model, find the graphics driver under drivers, and reinstall the latest one.

3. Test in Safe Mode

Sometimes third-party software or a system setting can interfere with external displays.

• Restart the laptop in Safe Mode:
  • Hold Shift while clicking Restart from the Start menu.
  • Select Troubleshoot > Advanced options > Startup Settings > Restart, and press F4 to start in Safe Mode.
• Once in Safe Mode, connect the monitor and see if the display works. If it does, the issue may be caused by a third-party app or setting.

4. Roll Back Recent Windows Updates

If the issue started after a recent update, it’s possible that a Windows update caused a compatibility issue.

• Go to Settings > Update & Security > Windows Update.
• Select "View update history".
• If you notice any recent updates, try rolling them back by selecting "Uninstall updates".

5. BIOS/UEFI Update

Occasionally, updating the BIOS/UEFI can help resolve hardware issues, including display problems:

• Visit the HP website for your laptop model and download the latest BIOS/UEFI update.
• Follow the instructions provided by HP to safely install the update.

6. HDMI Port or Hardware Issue

If none of the above steps work, it’s possible that there’s a hardware issue with your HDMI port.

• Test other peripherals on that HDMI port to see if they work.
• If nothing else works, it might be worth considering a repair or consultation with HP support to check if the HDMI port is faulty.

I hope this helps.
