html - Testing for multiple screens with javascript

Question

Is it possible to tell if the user of a website is using multiple monitors? I need to find the position of a popup but it's quite likely the user will have a multiple monitor setup. Whilst window.screenX etc. will give the position of the browser window it's useless for multiple monitors.

Answer 1

I do not believe that it is possible right now; however js is becoming more popular for desktop use in widgets in addition to web development and that would be an excellent feature to request for a future version
