Calibrating the Projector
Calibration sets up the connection between your computer and the
interactive pen. 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.
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 89 for more
information.
note
Do not select Exit or Quit
from the Easy Interactive
Driver menu. If you do, you
will have to open the driver
as described here the next
time you want to use the
interactive pen.
