calibrated? How to calibrate?
If you have installed the capacitance touch screen for the first
time or if the resolution of your computer has changed, you must

The calibration method is as follows: click the "pen and touch
screen" option in the control panel, and click the "calibration"
button. When the calibration interface is displayed, click the icon
on the interface in turn. After calibration, the calibration

"confirm" button.
