Dell ST2220T Monitor - Manual (Page 33)

Calibrating the Touch Screen
ST2220T uses standard Windows7 calibration:
1. Run Windows Control Panel -> Hardware & Sound -> Tablet PC -> Calibrate.
2. Touch your finger (or stylus) on the screen at that center of black cross until the cross moves.
3. The pointer moves to fifteen further positions in sequence for the first calibration and three further positions in sequence if previous calibration data is
stored.
4. Store the calibrated data to complete the touch screen calibration procedure.
This completes the touch screen calibration procedure.
