Calibrating the Touchscreen
After you connect your touch monitor
and install TouchWare, you must
calibrate the touchscreen. Calibration
serves two purposes:
•
Sets the active area of the
touchscreen
•
Aligns the touchscreen’s active area
to the underlying video
Calibration aligns the active touch-sensitive area of the touchscreen
with the video image on the display. Calibration also determines the
edges of the screen’s image and locates the center of the touchscreen.
If the screen is not calibrated properly, the active area of the
touchscreen may not be aligned with the video or may be unnecessarily
small in size.
To calibrate the touchscreen, open the Touchscreen control panel and
select Calibrate. Follow the directions displayed on the screen. For
more information on calibration, refer to the online help or the user
documentation for TouchWare.
Note:
Before calibrating the touchscreen, let the monitor warm up for
several minutes and then center the video image within the screen area.
Also, always calibrate the touchscreen at the monitor video resolution
that your touch application will use.
