    A very simple guide how to use the Windows calibration tool to obtain superior stylus accruacy compared to the stock data. This will, however, only work for software using the Windows calibration data (e.g. Sketchbook Pro and OneNote).

    How you do it.
    Uninstall the current Wacom drivers and reboot.
    Start => Control Panel => Hardware and Sound => Tablet PC Settings => Reset

    Start => type cmd and run as administrator. Paste following.
    Code:
    tabcal lincal novalidate XGridPts=5,15,30,50,70,90,120,259,513,767,1021,1180,1210,1240,1275 YGridPts=5,15,50,100,163,223,321,479,640,740,780,795
    This gives you 180 calibration points instead of only four. The result is an amazing accuracy over almost the whole screen!

    But if you want to change the tip preassure so must you install some kind of Wacom drivers again, and this might override the Windows calibration data. I believe the Lenovo driver has the worst accuracy, so I tried an old Fujitsu driver. This one was for me far better in secondary landscape mode than the Lenovo driver.

    Use the above method but WITH Wacom driver! :)

    1. Install the latest Wacom Tablet PC driver (or use lenovo update utility for latest "multitoch driver")
    2. Delete the following registry datas from regedit.

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TabletPC\LinearityData] - in my case i had to delete this one only since i never configured it before.
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TabletPC\UserLinearityData]
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002 \Device Parameters] - the VID_045E&PID_0799&MI_01&Col03 can be different.

    3. use the good old calibration command:
    Code:
    tabcal lincal novalidate XGridPts=5,15,30,50,70,90,120,259,513,767,1021,1180,1210,1240,1275 YGridPts=5,15,50,100,163,223,321,479,640,740,780,795
    Enjoy ultra accuracy with PRESSURE SENSITIVITY and Wacom support! :)
