    I have a CF-H2 - to be precise the sticker says "CF-H2FRAJV1M"

    I have a blank Win10 installation - so far using it is no problem.
    I have also installed all the drivers, so only one small thing left in the device manager where I cant find the drivers: Hardware ID is VEN_MAT DEV_0022 - some websites said something about intel chipset. But no luck so far by testing all the drivers from here:
    https://pc-dl.panasonic.co.jp/dl/search?q=cf-h2&button=&dc[]=&p1=&p2=&oc=&lang=

    Also the touchscreen does not work as expected:
    The outer centimeter does not work, if I click in that area the mouse jumps one centimeter to the center. So the Windows icon for example does not work. Also adjusting the screen in Windows does not really work.

    The confusing part: If I click on the screen when the system boots to get into the bios: The touchscreen works there. Including the last centimeter. So the hardware can't be the problem I think.

    The pen is the original one from Panasonic.
    In the device manager I have a "HID compatible pen", HID compatible screen" "HID compatible device that is defined by the cendor" and a "Wacom device" below "input devices".

    Any ideas? Thank you for help

    Your tablet is Dual Touch (Wacom + resistive). Do you have a wacom stylus? Does it work ok?
    The problem is with resistive touchscreen? Check whether this button is available and use it

    That option to reset the calibration is currently greyed out because I suppose there is no calibration stored.
    Also the calibration process does not work because I can not click on the X when they are so far in the corners: Even if I click exactly on the cross which is like a Milimeter from the outer corner I can see that the screen detects the click like a Centimeter to the inner part.

    Like in this pic:

    I have one stylus from HP and the original one from Panasonic, but both dont show the click on the screen where I click but a few centimeters away, use with fingers even if Windows gives me the option to calibrate that does not work at all.

    And the panasonic support says that they have not tested Windows 10 and even could not give me information what kind of drivers are used for the touch screen at all.
    The bios screen also does not have to be adjusted and works...

    Do you have access to a docking cradle?
    This with a mouse and keyboard might assist set up of your operating system

    Mouse and/or Keyboard is no problem.
    But even with that I have no idea what I need to setup in order to get the touch screen working in the end...

    Ok, Found out that the missing driver is the one for the shortcut keys on the right, so that puzzle is solved.
    And I have now done the calibration but clickt on finger instead of pen and it looks a little bit better already.

    Pen and finger use different layers of your touchsreen, that's why I asked you. You can't calibrate resistive touchscreen with Wacom digitizer stylus.

    I have h2. you can calibrate the screen in the bios. It works very well in windows and linux. Sometimes it messes up and prob hardware issue being older machine
