Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  
Use the video or graphics card driver to configure touch screen display settings.

1. Look for a graphics card or video card sticker on your computer. Common graphics cards include ATI, AMD, NVIDIA, and Intel.

2. Right-click an empty space on the desktop, and then click the Settings or Control option that matches your graphics card.

   Your graphics card control panel displays.

3. Click the Display, Arrange, or similar option, and then click Multiple Displays, if necessary.

4. Select the display option you want, such as Clone, Duplicate or Extended option.

5. Click Apply or Finish, if necessary.

After attaching an additional display, enhance and personalize your display.

• Taskbar: Right-click on the taskbar, and then select Taskbar settings. Click the drop-down menus to set your taskbar preferences.

• Start screen: On an extended desktop, the Start screen displays only on your primary monitor.

• App tiles (Windows 8 only): On the Start screen, drag tiles from one monitor to another. If the app is snapped, it snaps on the other monitor, too.

• Background image: Right-click anywhere on the desktop, and then click Personalize. Select images, colours, and themes.

Hope this helps! Keep me posted for further assistance.
