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 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. If the HDMI cable is connected to the HDMI1 port on the projector, make sure the USB cable is connected to the projector's USB-B1 port.
  • When connecting using Screen Mirroring, you need to set up your computer. Hold down the Windows key and press K on your keyboard at the same time, then select Allow mouse, keyboard, touch, and pen input from this device.
