This article explains the "single-touch" mode in the Elo driver settings

The “Single Touch Mode” setting allows the user to toggle between multi-touch and single-touch on multi-touch capable monitors. This is a global setting meaning that all supported touch monitors connected to the system will be limited to single-touch if the setting is enabled.



When Single-touch mode checkbox is checked, single-touch will be enforced for this device. When this checkbox is unchecked, action below will be taken:

• If the touch monitor is not yet calibrated: device's touch capacity will be set to the corresponding value as specified by MaxTouch under EloOptions.ini's [Setup Options] section;

• If the touch monitor is calibrated: device's touch capacity will be set to the corresponding value as specified by MaxTouch in per-monitor section; if the per-monitor section or MaxTouch entry does not exist in EloOptions.ini, then MaxTouch specified under [Setup Options] will be used if the entry exists (otherwise set to device's max capacity MaxTouch = 0).
