What should I do if my interactive pen does not follow or write, and it lags or skips?
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
on it, try restarting the the Easy Interactive Driver.
