Multi screen output can be done using Verge3D but is dependent on how your hardware is configured. If you are configuring your screens in a mural . An example might be a 2×4 grid making a 8K display out of HD displays…in which case you are using a multiplexer to deliver the content across those displays. Or if you are wanting a large screen on one side of the exhibt controlled by a smaller touch panel in a other portion of the room then it too will depend on your hardware configuration. If you are using two independent computers or if its being controlled by one. In these cases it will also depend if your content and app are stored local or on a webserver and how you have delievered the application …. electron app or web app.
You can have multiple canvas in one app that can be adjusted so they are displayed on independent screens. This may be the easiest method since your hardware list is known and will not change in a museum installation. There are other methods and options as well but to limit the amount of programming this may be a fast option.
Before going down the road of creating a museum interactive be your content and app are not needing to be run through their CMS or their web server and get all that worked out prior to developing your app as that will impact the best way to approach the problem.
