Hi @kamilOchal
We don't support multi-display out of the box. As far as I know the second screen has some flickering and it doesn't extend the display but mirrors the first one. If you have some budget we can talk about a project and take a look into it.
What might also be an option is Android's Split Screen. If the two displays would be facing the same way anyway, you can use a slightly larger display and show one app on the left and one on the right side of the screen.
