How multi display using UWP

I’m trying to develop an uwp app, the application use two monitors, because this app will run on windows and on a surface. But when I change on build settings to windows store the option of display on the camera component disappear.

I’m trying to do this because now vuforia has released support for uwp apps, but on my application I need to use two monitors but I can’t make it work.

I don’t know how to do multi-monitors in UWP.

For the root of your problem, Vuforia on a PC. I did find http://holographi.space/ , a $250 plugin that gets Vuforia to do Standalone PC builds. I haven’t forked over the $250 yet, so don’t know if it really works. After it’s a PC build multi-monitor is much easier.
