Dual display support for Android

Hello everyone,

I am trying to build an Ionic Framework App for an Android device that also has a secondary monitor.

I found the Presentation API:

and a simple demo:

https://googlechrome.github.io/samples/presentation-api/

which I successfully tested on a Windows laptop with an external HDMI screen.

I do not have the Android device yet, so instead I tried using the “simulate second screen” function in the Developer Options of a Samsung Galaxy Tab A tablet. However, when I go to the demo page, it does not detect my secondary display. In the specifications it says that Chrome versions above 48 should support this, and I am running Chrome 73, and android > 7 but the simulated secondary screen only mirrors the main screen, and is not detected in the browser.

Has anyone ever built an app for a dual-display device?
