Solutions When You Cannot Operate a Computer from the Projected Screen

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.
