9 What to do if calibration is still inaccurate even after calibrating in V-sense & windows
If you calibrated using the V-sense drivers & windows calibration, if there are no black borders
on the PC screen or the i3TOUCH image but still the calibration is not accurate, go to "screen
resolution" (see step 7) and choose "extend" instead of duplicate and apply.
Now go to "control panel" -> "tablet PC settings" (windows 7 / windows 8)
Follow the on-screen instructions. Tap on the i3TOUCH when the below instructions are shown
on the display or press "enter" when you read the instructions on your computer screen only.
With this step you identify the i3TOUCH as the touch screen to be used in windows. Finish with
"escape".
Touch the i3TOUCH and check if it recognizes touch, regardless to it's accuracy. Then check
the accuracy of the touch. If not accurate, calibrate using the V-sense driver calibration. If still
not accurate after calibration, go to screen resolution and choose "duplicate" again to duplicate
your computer screen on the i3TOUCH.
