Can I extend my ipad’s screen to a second display or only mirror?

Hi,

I found plenty of ways to use my iPad as a second display, but now I actually want THE OPPOSITE: I want to work from my iPad, but would love to use my second screen to display something other than what’s on the current iPad view (e.g. a webpage while I work on the main screen).

Is that possible at all, and if yes, how?

Thanks

F
