Calibration
sets up the connection between your computer and the interactive
pen so that you can control or interact with the image being
projected from the computer. This simple process ensures that your
computer can accurately detect the position of the pen on the
projection surface.
You need to calibrate before using the pen for the first time,
or if you change the resolution on your computer or connect a
different computer. You can use either pen for calibration.
Two types of calibration are available:
- Normal, which is faster and appropriate for most
situations (25 calibration points)
- Advanced, which is recommended when you need
higher accuracy (49 calibration points)
You may need to recalibrate if you change the projector's aspect
ratio or if you change the following settings: Auto Setup, Resolution, Tracking, Sync,
Position, Aspect, Keystone,
or Zoom.
