The article explains Cursor Edge Acceleration in the Elo driver

The Cursor Edge Acceleration tool is used to increase sensitivity along the edges of the touch screen. This option allows users to access areas of the screen that would otherwise be limited by the frame of the monitor. Note that CEA may not be configured until the monitor has been calibrated.





To enable CEA, click on the "Select Default" button and specify the desired parameters. The position of CEA may be manipulated for all edges at once by means of the “Increase/Decrease CEA Area” buttons, or individually by means of the arrows along each edge. Additionally, CEA for edges may be disabled by unchecking their respective box.

The user will also be given the option to select between CEA speed settings (slow, medium, and fast).

The user must click “Apply” before closing/exiting out of the utility for any changes to take effect. To disable CEA, click on the “Turn off CEA” button.
