Solutions When You Cannot Operate a Computer
from the Projected Screen
If you cannot operate 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. See your projector's Installation Guide for details.
• Make sure the USB cable is securely connected. Disconnect the USB cable,
and then reconnect it.
• Make sure PC Interactivity is turned on in the toolbar.
• When connecting using a 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.

Solutions When the Interactive Pen Position is not
Accurate
If the pen position is not the same as the mouse pointer, 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. If the cursor location and pen position do not match after auto
calibration, you can calibrate manually. See your projector's Installation
Guide for details.
• Try adjusting the pen operation area.

features.
