Fine Coordinate Correction — After you calibrate the touch screen, the Touch Point (2) and
cursor should be located directly underneath your finger when you touch the screen. However, you
may prefer to offset the Optical Point (1) or cursor slightly above your touch point so you can see
the cursor and point more easily and precisely to small objects. The Touch Cursor Shift option lets
you define the distance between your fingertip and the position of the cursor on the screen.
Offsetting the cursor is helpful when selecting small items, such as single letters in word processing,
check boxes, or radio buttons. Click [Up] [Down] [Left] [Right] to make X or Y offset. Click Reset
to restore to default.

Screen Shift Correction — It is possible for the screen image to extend beyond the edge of the
monitor bezel. In this case, it may be difficult to touch items at the left and right edges of the screen.
Normally a monitor has an auto scaling function to correct. However, you can use the Screen shift
function to adjust the auto scaled image for more accuracy. Click [X Zoom (+or-)] and [Y Zoom
(+or-)] to adjust the screen image. Click Reset to restore to default.
