The Cursor Moves Erratically

  1. Make sure nothing is blocking the optics of the touch screen. There are three sensors in the top corners and the bottom left corner of the screen that need unobstructed views across the surface of the display to the opposite edges of the screen.
  2. Clean the panel surface and edges of the screen.
  3. If the steps above do not work, restart the computer and turn the ST2220T monitor off and back on.
