I have my main screen, which is a touch screen. I also have an [asus zenscreen go portable monitor][/https://www.asus.com/us/Monitors/ZenScreen-MB16AHP/]. The zenscreen is touchscreen as well. However, the mapping of touch inputs on the zenscreen is to the default laptop screen. Other than this, everything appears to be working fine.
