Touch Calibration — Use this tool to calibrate the touch screen.
NOTE:
Specifically, calibration defines the dimensions of the active area of the touch screen and locates
the center of the touch screen. If the screen is not calibrated, the active area of the touch screen
may not be aligned properly or may be unnecessarily small in size. Once calibrated, the information
is saved by the touch screen for each video resolution. Therefore, you only need to re-calibrate the
touch screen the first time you change to a particular video resolution.
Clicking Auto calibration runs a calibration process automatically based on the resolution without
user interaction. For more accuracy, use the following instructions and also refer to the Fine
Coordinate Correction function section later in this chapter.

The calibration process aligns the touch screen with the underlying monitor images.
Click Calibration. This starts the calibration process. When the black screen displays, a
blinking circle guides you through the calibration process pointing to the appropriate target.
Touch the screen with your fingertip positioned at the center of the circle. The circle will stop
blinking and display a white filled circle.
Touch each additional calibration target until all the circles stop blinking. After this action, the
process ends and the calibration screen closes.
NOTE: When using the Aspect Ratio Control function, if you set the aspect ratio to 4:3 on a
16:9 panel or 16.9 on a 4:3 panel, make sure the touch screen active area is set to the same
scale using manual calibration.
