I have a Windows 10 machine with a built-in touch screen. When I connect a second display the system defaults to extend mode then I switch it to clone mode with the touch screen set as primary.
The issue is my touch screen becomes inaccurate. It behaves as if it is set to a different resolution than the display. Middle screen touches are more or less correct and the touch gets further off as you get closer to the edge of the screen.
Drivers: Intel(R) Graphics Driver: 10.18.10.4252 Touch Screen appears to not have a driver installed, from what I can tell Windows is taking care of it. I did try to install Penmount but saw the same behavior so it was uninstalled.
Touch screen calibration under pen and touch settings does not work as it is not possible to touch the calibration cross hairs at the edge of the screen.
One fix was to put the unit back in extend mode, use setup in tablet settings, select my touch screen, then put it back in clone mode.
I need to better understand what is causing the touch screen to become inaccurate and hopefully find a way to stop this from happening. This will ultimately become a medical device in sort of a kiosk mode. It will be connected to a wide range of external displays that I will know nothing about.
