Intel Wireless Display - What is it?

I just assembled a computer with an I7 3770K using an Intel DZ68DB motherboard.
There is no WiFi installed. Works fine.

The processor specs say the I7 has Intel Wireless Display.

First, what can I do with Wireless Display? Can it do a wireless display of the normal computer screen? Does it substitute for the cable? Any limits on what it can be used for? Most of the stuff I find talks about TV, movies, pictures. Not sure if that is marketing or a real constraint. Will it handle the web, Excel, and word processor stuff as well?

What do I need to make it work? Will a garden variety PCI wireless card work?
What goes on the monitor so it can receive?

Recommendations for hardware that works well with this?

A wireless screen is all new to me, so any help is appreciated. Thanks.

Intel's Wireless Display is also known as WiDi (http://www.cnet.com/8301-31045_1-10424576-269.html).  It's not a feature of the processor, but requires a combination of specific Core processors, Intel HD graphics, Intel Centrino wireless and Intel software installed.  You also need a receiver for the TV.

It's nothing that you couldn't have already done using a wireless VGA transmitter and receiver http://www.iogear.com/product/GUWAVKIT2/.
