Leonardo,
Intel� Wireless Display (Intel� WiDi) — Updating to the latest version of Intel� WiDi
Head there, you need to update your drivers and install the WiDi app, then join the TV to your network (the same one your laptop is on) and use the WiDi app to find the TV and connect to it. (Don't install the widget)
To the topic at hand,
Turns out, I have Single Band Wireless NIC's in the laptops we purchased, we've already issued them to users and went with NUC's for our solution. (which work extremely well, the i3's and the i5's).
I don't think we'll be using WiDi as a solution like this again, probably just stick to conference room TV's.
