Intel WiDi dual display support?

Question

I'm looking forward to purchase Intel WiDi adapter for my TV. But does WiDi support dual display? Meaning, not just translating my laptop screen to TV, but actually using both simultaneously, s.t. TV is used as a second display? To obtain result similar to this setup.

Answer 1

Its actually called extended mode:

and, if I'm not mistaken, it is supported in windows 7 by default (Win+P shortcut). And Wi-Di seems to support it as well, as mentioned at Intel Support.
