Why can't I use 10 touch points on my LG 84TR3B Digital Signage in Windows 7/8.x?
- V
  Valerie NguyenSep 7, 2025
  If you cannot use 10 touch points on your LG Digital Signage in Windows 7 / 8.x, ensure that the content you are using supports up to 10 touch points. Try removing the USB cable and reconnecting it after 10 seconds, or running the content (e.g., Flash Player, Paint, etc.) again. Restarting your PC may also help. Note that touch errors may occur if the gap between two touch points is 20 mm (0.78 inches) or less, and 10 touch points may work unstably on the edge of the touch screen.
