How to Calibrate Windows Touchscreen Devices
The touchscreen calibration tool works by displaying a pattern on the screen and then overlaying it with a series of crosshairs. By tapping each crosshair in sequence, you show Windows exactly how to configure the touchscreen. When calibrating a touchscreen, it’s essential to tap the actual location of each crosshair. If you tap anywhere else, you end up with an improperly configured touchscreen that may be unusable. In that case, connect a keyboard and mouse to reactivate the configuration tool.
What to Do If Your Touchscreen Still Doesn’t Work Correctly
Configuration issues don’t cause all touchscreen problems. For instance, if the touchscreen doesn’t work at all, it might be turned off or disabled, or the correct driver might not be installed. In that case, enable the touchscreen or update the drivers. In other cases, figuring out why a touchscreen doesn’t work can be more complicated. If calibrating your touchscreen didn’t help, check out our in-depth guide to fixing a broken touchscreen.
