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.
