Configuration of a touch screen monitor

English Hardware
1

Hello,

a small question about touchscreens. I recently got two monitors, one with touch and one without. Both are perfectly recognized and I can work with both (extended workspace, which extends over both screens.
The touch functionality also works basically - but not as I would like it to. The touch activity is carried out over the whole width. I.e. if I touch in the left part of my touch screen, the action will be executed in the left screen, which has no touch at all.

How can I adjust that the touch functionality is actually only executed in the area of the touch screen?

Greeting
Torsten

I don’t own such hardware, so can’t offer anything more than general advice, but this might be a good place to start…

Thank you, it really was helpful. I needed some time to get a working configuration, but the best result I have is:

xinput set-prop "Wistron Corporation Optical Touch Screen" --type=float "Coordinate Transformation Matrix" 0.334000, 0.000000, 0.334000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000

Thanks for the update, and good to read that it helped with calibrating your touchscreen.
