  If the screen color is abnormal on your LG Digital Signage, set the number of colors to more than 24 bits (true color) via Control Panel - Display - Settings - Color Table menu in Windows. Also, check the connection status of the signal cable and re-insert the PC video card. Note that several pixels (red, green, white or black color) may appear on the screen, which is attributable to the unique characteristics of the LCD panel and not a malfunction.

Why can't I use 10 touch points on my LG Digital Signage in Windows 7?
- S
  Susan LongSep 1, 2025
  If you cannot use 10 touch points on your LG Digital Signage in Windows 7, ensure you are using content that supports up to 10 touch points. Try removing and reconnecting the USB cable after 10 seconds, or running the content again. Restarting your PC may also help. Note that touch errors may occur if the gap between two touch points is 15 mm or less, and 10 touch points may be less reliable on the edge of the touch screen.
