Webapp in 2 monitors

Question

I am trying to find a way how to build a browser web app that runs in 2 monitors, like; i have a secondary monitor that i want to put there some window , i want it fullscreen, and automatically in the secondary, so no drags, while the main app should stay in the primary monitor, where is the browser... no way seems, nothing really works so the only way seems to be with some desktop app. I don't really care if the solution is browser dependent at this point, but still can't find a real solution.

Does a ny body tried something like this and can give me some ideas how to build it?

EDIT ... i need the second monitor to have some specific content, so not a clone of the primary... kind of... i'm playing some game in the first monitor and i see statistics on the second...

Answer 1

What you are trying to do is not possible yet , but there is a Presentation API that is being discussed that would let you do exactly what you are looking for:

This specification defines an API to enable web content to access external presentation-type displays and use them for presenting web content.

Unfortunately, it seems like there are no browser implementations yet.

Your only other option right now is to use 2 independent browser pages that communicate with each other somehow ( LocalStorage , WebSockets etc.).
