A different position on the touch display from the position I touch responds. I calibrated the touch display, but this did not fix the problem.

Pay attention to the following when setting [TOUCH DISPLAY CALIBRATION] in the [UTILITY] screen.
When calibrating, use a touch pen or other object with a narrow tip to touch the center of the point at which the + marks that are displayed intersect.
The calibration may not be accurate if you use your finger when calibrating.
