Hi,


I was wondering what user agents were expected to do when a single page is being displayed on two (or more) output devices at the same time.


For example, if I’ve a 1920x1080 10in tablet that I use to project to a 1920x1080 TV (=duplicate), what should media queries as media type, as resolution? Should the browser ignore the TV or should it relayout the page on the tablet to match the TV type? Is it undefined?


My second question is: what happens if multiple screens are used to create a single display surface, especially if the screens have different sizes, resolution and/or ratio (ie: 1920x1080 next to a 1280x1024 screen); is there an expected behavior in such case?


In the first case, it’s easy to define a ‘primary’ display and stick to it, but when the screens are merged into a bigger drawing surface, the characteristics of the newly formed screen may be pretty unusual. However, in most of the cases, a window fits completely inside one or the other screen (but maybe not all the times).


Any thought on that?

François
