Not able to select/sculpt when displaying 2 screens

THE PLATFORM: iPad, Android, Windows, MacOS, etc
NOMAD APP VERSION: 2.xx

I’m using Huion Kamvas 16 2019 (latest update) and also displaying on BenQ monitor running windows nomad sculpt version.

I can drawing/sculpt normal but got the benQ for its color display. When I extend the screen to copy the huion I can only move my sculpt. I can only use the mouse on the pc to sculpt.

Is there away to fix where I can display on The BenQ and draw normal on kamvas like normal.

Windows has 2 mode: extended vs mirror.
Do you use extended?

Not sure if it can help but maybe try toggling off (or on) “Wintab” in the nomad menu (top-left).
