Touchscreen issue using as secondary display for Windows 10

[phantom48v]

Hello,

Im using the display as a secondary screen for my windows 10 computer. The driver is successfully installed and the screen work quite nice. im just running into one issue. when i try to use the touchscreen the mouse cursor jumps to my primary/main screen and I cant tap on objects on the 7 inch it would make cursor jump to primary screen and act like a trackpad for it, basically. How can i use the touch function correctly where i can touch the 7 inch screen and the mouse cursor goes there ?

Thank you
