I can't use the pen as a mouse to control the computer from the projected screen. What should I do?

• If you are unable to access a computer from the projected screen, try the following solutions:

  • Make sure the USB Display setting in the Signal I/O menu is set to On.
  • Make sure you perform pen calibration when using the interactive pen for the first time so that the projector recognizes the position of the pen correctly.
  • Make sure PC Interactivity is turned on in the projector's interactive toolbar.
  • Make sure the USB cable is securely connected. Disconnect the USB cable, and then reconnect it.
