@cmkramer87, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding the ports not recognizing the monitor! 

We're thrilled to have the opportunity to assist you and provide a solution.  

It sounds like your HP Pavilion Laptop isn't detecting your external monitor through USB-C, HDMI, or USB ports. Here are some troubleshooting steps to resolve the issue:

Check the Monitor & Cable:

• Make sure the external monitor is powered on.
• Try using a different HDMI/USB-C cable.
• Test the monitor with another device to confirm it's working.

Verify the Connection Type:

• If you're using a USB-C to HDMI adapter, ensure it's a compatible video-supported adapter.
• If your USB-C port does not support video output (DisplayPort Alt Mode), you may need a USB-C docking station that provides video output.

Detect the Monitor Manually:

• Right-click on the desktop and select Display settings > Multiple displays > Click Detect.

Check Display Output Mode:

• Press Windows + P and select Extend, Duplicate, or Second screen only based on your preference.

Update/Reinstall Graphics Drivers:

• Open Device Manager (Win + X > Device Manager)
• Expand Display adapters
• Right-click your GPU (Intel or NVIDIA) > Select Update driver
• If updating doesn't work, try Uninstall device > Restart your laptop

Check Windows Updates:

• Go to Settings > Windows Update and install any pending updates.  

Let me know if this works!

Take care, and have an amazing day!

Thank you for the reply!  It was a big help.  I ended up reinstalling a more general graphics driver and that seemed to work.  I'm typing this response on the extended screen so that's a plus!

Thank you again!
