How to know if the touch is incorrect?

First, the finger touches the device screen, but the cursor does not appear on the right.


How to solve this problem?

Please perform the calibration steps: (open the touch screen calibration program)


1) Install the touch driver on the device for the first time.


2) Change the resolution every time.


3) Change the panel frequency every time.


4) The cursor does not correspond to the touched point every time.


After calibration, the calibrated data will be stored in the register of the controller, so there is no need to calibrate the screen every time the system is started.
