CONFIGURE THE TOUCH DISPLAY
As we know, the touch screen connected is set to control the main display by
default, sometimes we need to make the touch to control other display than the main
display if we set the touch screen as second display. Herein we show you how to
configure it.
1. Open Tablet PC Settings from Control Panel
2. Open the Tablet PC Settings, and click Setup…:

3. Following the hint to finish setting:
hints:
Tap this screen with a single finger to identify it as the touchscreen. If this is
not the Tablet PC screen, press Enter to move to the next screen. To close the toll,
press Esc
.
For example:
I connect a big size display and one touch screen to my PC (Windows 10), the big
display is recognized as display 1 (the main display), the touch screen is
recognized as display 2 (the second display). Before tablet setting, the touch
screen controls the main display if I touch it. Now I want to make the touch screen
to control itself-the second display.
So, I click Setup…, the hint appears on display 1 and display 2 is white. I press
Enter, the hint turns to display 2 and display 1 is white. I tap the center of the
touch screen (display 2). The setting is finish, and now if I tap the touch screen, I
can control the display 2 with the touch screen instead of main display.
