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.
