Mapping the touch screen input to the touch sensitive screen only

asked 2017-04-05 03:17:59 -0600

I have a Lenovo Yoga 510 notebook, with a touch screen. If I have only the notebook’s screen, everything works fine(ish; there is a small lag, but I can live with that). But if I attach a HDMI screen, the touch screen coordinates get messed up, as if the new screen would have extended the touch screens dimensions (hence, when the additional screen is configured to be above the notebook screen, and I tap on the top of the touch screen, the window on the external monitor receives the event).

Is there a way to map touch input only to the touch sensitive screen?
