Calibrating the Projector
Calibration sets up the connection between your computer and the
interactive pens. 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 pens 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
using the remote control, or if you change the following settings in the
projector’s menu system:
■
Settings menu:
Keystone
or
Zoom
. See page 75 for more
