Dual screen kiosk mode in ChromeOS on Chromebox? - google-chrome-app

Question

I've found a few places that talk about trying to extend a window between screens, have enabled the unified desktop tag, which didn't work.
I've also found a few places talking about doing this in Windows that use Win32 calls to do it, which is useless for ChromeOS.
All I need is to put a second web view on the second screen. It doesn't need to be an extended window. I just need to do something like this:
chrome.app.runtime.onLaunched.addListener(function() {
var screenOne = {
'id': 'mainwin',
'bounds': {
'width': 768,
'height': 1360
}
};
var screenTwo = {
'id': 'secondwin',
'bounds': {
'left':768+768,
'width': 768,
'height': 1360
}
};
chrome.power.requestKeepAwake("display");
chrome.app.window.create('../index.html', (screenOne));
chrome.app.window.create('../screen2/index.html', (screenTwo));
});
Also, bonus points on a solution that works in the simulator.

Here's my solution, which works beautifully. It requires you to add system.display to the permissions object in manifest.json
chrome.app.runtime.onLaunched.addListener(function() {
var screenUrls = ['../index.html','../screen2/index.html'];
chrome.system.display.getInfo(function(displays){
for(var id in displays){
var display = {
id: displays[id].id,
bounds:displays[id].bounds
};
chrome.app.window.create(screenUrls[id], display);
}
});
chrome.power.requestKeepAwake("display");
});
