Calibrate your pen display to align the screen cursor with the position of the pen on the screen. This compensates for viewing angle and adjusts for parallax.
Open Wacom Tablet Properties by using the search feature.
Select the Calibrate tab.
Click Calibrate... to activate the calibration screen. Monitor 1 should be selected.
Use the pen tip to click on the center of the crosshairs in the upper-left corner.
Click on the center of the crosshairs that are displayed in the remaining corners.
Test the alignment by positioning the pen at a few different points on the display.
Click OK to accept the calibration, or Try Again to recalibrate.
