    Hello, I have a calibration problem with 7" screen and touch panel.
    On the left side, very close to border (up to 1 cm) in the middle of the screen height, the panel is shifting the input horisontaly about 1 cm right. In the left corners it works very well, I can press the Start button, but I can't press the power off buton because my touch is reported about 1-2cm to the right from the place touched.
    Here is the video: https://drive.google.com/open?id=0B5ACh ... Gpsc2RBRWM

    I had other problem with that screen, before the touch panel driver update it was shifting touch at the right side of the screen, I could't touch the X button for closing of the windows.

    One weird thing I have noticed is that in "Tablet PC settings" in display options there is that the panel is: 1.digital flat panel (640x480 60Hz).

    Any ideas how to make this touch panel work properly?
    Thanks, Marek

    Have the same problem here.
    Offset starts ca. in the middle of the screen and grows exponentionally.
    Touch calibration is not possible.. I can not touch the right calibration points, for the touchrecognition is offset... just as Marek described.

    Any Idea would help (having 4 devices with identical setup and same problem... )
    Regards
    Ole
