Well, simple situation. Is it possible to detect if a user has a dual monitor setup from a web application?
If this is possible, is it possible to open a child browser page on this second monitor, so the new window doesn’t overlap the old one?

Reason why I ask: I’m working on a web application and at home I have a dual-monitor system. When I go to the administration part of this site, I want it to open in a new browser, preferably on the other desktop. Of course, I could just click, then drag the new window, but doing this automatically seems more fun. 🙂

Don’t think JavaScript has the proper functions for this. How about Java itself?

    I don’t think you’ll be able to directly detect a dual monitor setup, but you can probably make a good guess by looking at their screen resolution, using javascript’s screen.width and screen.height. If the ratio of the width to the height is 8:3, its a good chance they have 2 standard 4:3 monitors side by side. You can do a similar calculation for 16:9 or 16:10.
