HI @TarnaskyT,

Welcome to HP Support Community.

Thank you for posting your query,If your touchscreen stopped working after connecting your device to a second monitor, here are some troubleshooting steps you can follow to resolve the issue:

1. Restart Your Device

1. Power Cycle:
   • Completely shut down your device.Wait for about 30 seconds to a minute.
   • Turn your device back on to see if the touchscreen functionality is restored.

2. Check for Touchscreen Drivers

Update or Reinstall Drivers:

• Go to Device Manager (you can search for it in the Start menu).Expand the section labeled Human Interface Devices (HID).
• Look for HID-compliant touch screen or a similar entry.Right-click on it and select Update driver. Follow the prompts to search automatically for updated driver software.
• If updating doesn’t work, try right-clicking and selecting Uninstall device. Restart your device, and Windows should attempt to reinstall the driver automatically.

Check for Windows Updates:

• Sometimes, updates may include fixes for hardware issues.Go to Settings > Update & Security > Windows Update and check for updates.

3. Calibrate the Touchscreen

• Go to Control Panel (you can search for it in the Start menu).
• Click on Hardware and Sound, and then Tablet PC Settings (you might need to switch to large icons view if you don’t see it).
• Go to the Display tab and click on Calibrate to open the calibration tool.
• Follow the on-screen instructions to calibrate the touchscreen.

4. Check Touchscreen Settings

• Sometimes the touchscreen might be disabled.
• Open Device Manager, expand Human Interface Devices, and right-click on HID-compliant touch screen. Ensure that it is enabled.
• If the touchscreen option is missing from HID, it might be a sign of a hardware issue or that the driver is not correctly installed.

5. Test Touchscreen in BIOS/UEFI

• Restart your device and enter the BIOS/UEFI settings (usually by pressing Esc, F2, F10, or Del during startup).
• Check if the touchscreen works in the BIOS/UEFI environment.
• This suggests that the issue might be related to software or driver conflicts within Windows.

6. Check for Physical Damage

1. Inspect the Screen:
   • Check for any visible damage to the touchscreen or surrounding area.
   • If there is any damage, it might need professional repair.

7. Test with a Different Monitor

• Disconnect the external monitor and see if the touchscreen functionality is restored.
• If it is, reconnect the external monitor and check settings related to display and touchscreen configuration.

8. Perform a System Restore:

• If the touchscreen was working before and you have a restore point created, you can perform a system restore to revert your system back to a point where the touchscreen was functioning.
• Go to Control Panel > System and Security > System > System Protection > System Restore. I will be glad to help you.

I hope this helps.

Take care and have a good day.
