If a touchscreen displays correctly but records touch at the wrong position, what may be required?

Answer and explanation

Correct answer: Touch calibration or a related driver correction

The governing concept is coordinate mapping between an input surface and the displayed image. Since the visual output is correct but the touch location is offset, the screen must be recalibrated or its touch driver corrected so physical coordinates match screen coordinates. Option A is correct. Formatting a disk, replacing a printer, or removing a sound card does not repair touchscreen coordinate mapping.
