Default Dell3100 USB docking and 2-4pcs Touch screens Dell p2314T and HP EliteBook8570

Dell3100 USB docking and 2-4pcs Touch screens Dell p2314T and HP EliteBook8570 (graphic AMD M4000) with W10
……………………………………………………………………………………………………………………………………
I would like to use between 2 and 4 Touch screens with HP EliteBook8570 (graphic AMD M4000) with W10. 3 pcs of Dell p2314T via Dell3100 USB docking and 1 pcs of Dell p2314T directly via DisplayPort. According to specification, it is possible to have 5 screens for graphical card AMD M4000.
If I connect one touch screen via dell3100, it is working and touch points are on the monitor Dellp2314t. I can use it without problem.
The problem is, when I connect two and more touch screens. The touch points are always visible on the main screen of HP EliteBook8570. I would like to use each monitor and its touch screen separately. How can I solve this problem to have the touch points on monitors only?
It is W10 problem? Or it is problem with HID – compliant touch screen driver or Dell3100 USB docking or monitors Dellp2314T? Each touch monitor would need a unique listing of itself and its USB upstream cable listed in the Windows 10 device manager. How to setup this? Is it even possible through the Dell3100 docking? Zip file is enclosed. Thank you in advance for your help.

It sounds like this is just Windows not mapping the touch inputs to the correct display.

Search for the word 'Calibrate' from the Start Menu and select the result for 'Calibrate the screen for pen or touch input'. From the window that appears select the 'Setup' button from the 'Configure' section and follow the wizard to identify which screens are touch-enabled.

Once complete, select the appropriate monitor in the 'Display' drop-down box under the 'Display Options' section and select 'Calibrate' and then follow the wizard (do this for each touch-enabled display).

Does that help?

Thank you for the answer.
When 1 touch monitor Dellp2314t is connected via USB3 Dell3100 docking with USB3 for upstream for touching, I can do calibration on its.
When 2 touch monitor Dellp2314t are connected via USB3 Dell3100 docking, with USB3 for upstream for touching via Dell3100 or directly to HP8570W, I am not able to do calibration touch screen monitors. Only on main ones. See enclosed screenshots.
Where is a problem?
How can I distinguish between monitors and their USB upstream?
It is question of W10 and some setup in registry?
Or it is question of HID compliant touch screen?
How can I solve this problem?

Thank you once more for help to everyone.
