You are using a touchscreen in a multimonitor environment. In this case, it can happen that the touchscreen coordinate matrix expands over both monitors, with the result that the monitor interprets the touch point in a wrong way.


You touch the touchscreen in its center and the cursor moves between the two screens.


To avoid the unrequested expansion of the touchscreen matrix you have to select the correct touchscreen connection type in the setup:

  1. Click User Interface > Input > Touchscreen in the IGEL setup.
  2. Select the correct connection type under Multi Monitor > Touchscreen Monitor.
