Touchscreen Issues

[nmki]

Hello. I have an HP Compaq L2206tm touchscreen monitor, but the touch function is not working (nothing happens what I touch the screen). However, it sometimes touches random points on my computer screen (including my second monitor which is not a touchscreen). My PC (Windows 11) detects touch support with 2 touch points, and all of the latest drivers are installed.
So far I have tried the following: Connecting it to different USB ports, cleaning the screen, ensuring native resolutions are set currently, reinstalling drivers, resetting the screen, running diagnostics (troubleshooter), updating monitor and computer firmware, trying different USB cables, ensuring touch is supported and enabled.
Despite these efforts, the issue persists. How can I restore the touch functionality?

Hi @nmki,

Welcome to HP Support Community.

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

I understand how frustrating it can be when your touchscreen monitor isn’t responding properly, especially when it randomly registers touches on another screen. You’ve already done a thorough job troubleshooting—trying different USB ports, cleaning the screen, reinstalling drivers, resetting the monitor, updating firmware, and more.

Since the issue persists, let’s try a few additional steps:

1. Check if the Touchscreen Works in BIOS

This will help determine if the issue is hardware-related or caused by Windows settings.

• Restart your PC and press F10 repeatedly as it boots to enter the BIOS (on some PCs, it may be Esc, F2, or another key).
• Try touching the screen while in the BIOS menu.
  • If touch works in BIOS, the issue is likely software-related—continue with the steps below.
  • If touch does NOT work, it could indicate a hardware issue with the monitor.

2. Check for Windows Updates

• Go to Settings > Windows Update.
• Click Check for updates and install any available updates.
• Restart your PC after updating and test the touchscreen.

3. Update the BIOS (Firmware)

Updating the BIOS can resolve hardware compatibility issues:

Find Your BIOS Version

• Press Win + R, type msinfo32, and press Enter.
• Look for BIOS Version/Date and note it down.

Download the Latest BIOS Update

• Go to the HP Support website.
• Enter your PC model and look for BIOS updates under "Drivers & Downloads."
• If a newer version is available, download it.

Install the BIOS Update

• Run the downloaded BIOS update file and follow the on-screen instructions.
• Do not turn off your PC during the update.

Restart and Test

• After updating the BIOS, restart your PC and check if the touchscreen is working.

4. Ensure Windows is Detecting the Correct Touchscreen Display

• Go to Settings > System > Display.
• Click Identify to ensure Windows recognizes the correct display.
• If touches appear on the wrong monitor:
  • Search "Calibrate the screen for pen or touch input" in the Start menu.
  • Click Setup under "Configure your pen and touch displays" and follow the instructions.

I hope this helps.

Take care and have a good day.

Hello! First of all, thank you for answering!
I have already discovered (after posting here) that this issue is not software-related, so your steps are not relevant to me.
Thanks!

You're very welcome! I appreciate the update, and I understand that since you've determined the issue isn't software-related, my previous steps may not apply.

Would you like assistance with further troubleshooting on the hardware side, or are you considering repair/replacement options for the monitor? Let me know how you'd like to proceed—I’m happy to help! 

Best regards,
