If multi-touch is not responding on your LG Digital Signage, the content played (e.g., Flash Player, Paint, etc.) may not support multi-touch points. Make sure you use content that supports multi-touch points. Also, try removing the USB cable and connecting it again in 10 seconds. You can also try running the content again or restarting your PC.
