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.
Select Start , then open Settings . Under System , select Display . Your PC should automatically detect your monitors and show your desktop. If you don't see the monitors, select Multiple displays , then Detect.
Yes, most browser locking software can detect the attempted use of multiple monitors or screen-sharing on the primary device.
So, in this sense, the answer is no; websites cant detect user activities like screen capture. However, if the website has you download some software and install it, it can most probably recognize external screen capture tools being used on their web pages (if they want to).
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
