Q:
What should I do if my interactive pen does not follow or write, and it lags or skips?
A:
Try the following:

  • Recalibrate your pen.


  • If the cable cover is not attached, make sure the cables are not blocking the signal.


  • Make sure the pen batteries have enough power. If the light on the pen doesn't turn green when you press the button, you need to replace the batteries.


  • Dim the room lights and turn off any fluorescent lights. Make sure the projection surface and the pen receiver are not in direct sunlight or other sources of bright lighting.


  • Connect the USB cable directly from the computer to the projector, not through a hub. Make sure the USB cable is securely connected to the projector and computer. Try disconnecting and reconnecting the cable to your computer.


  • From your operating system's Display utility, select Settings > Advanced > Troubleshoot, and set Hardware acceleration to None.


  • Make sure the signal is set to Computer and not USB Display.


  • Update your computer's video driver.


  • If your interactive pen icon has an X icon
    • on it, try restarting the the Easy Interactive Driver.
