Quartz problem with touchscreen monitor

[CheWoo]

Hello,

Recently we bought Iiyama T2454MSC B1AG touchscreen monitor.
We plugged it in Quartz 16.0 and we have image, touch is working but there comes an issue. When you perform a touch on the Iiyama, the touch also occures on Quartz's monitor, so basically it looks like you click with a mouse and it does something on both screens.

We set it up as external display, checked everything we knew many times, nothing looks wrong nor we can find any setting that has any connection to the issue.

Please, if you have any idea or way to help, would be very thankful if you do.

Best regards
