Calibrating the Projector
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.
