Intel wants Wireless Display to be a simple experience for the user and they tout a single-button solution to get this all working with your TV. I can say that their claims are true and I was able to get the whole thing set up in about 5 minutes (excluding the time required to install the software, which would have been pre-installed with a retail bundle).

There are three software components to install if you need to update or reinstall your drivers: the Intel Graphics driver, Intel Wireless driver, and the Intel Wireless Display software. Assuming you have these parts already installed, you're ready to get Wi-Di running.

First connect the adapter to your HDMI-enabled display (you can also use RCA if needed) and turn the adapter on. Turning on your display to the correct input will give a screen prompting you to run the Wireless Display software from the notebook (above picture).

On the notebook (assuming the wireless adapter is turned on) the Intel Wireless Display software should list any detected Wi-Di capable adapters within the broadcast radius. You then simply select the correct adapter from the list and then connect.

On your TV, there will now be a security code and on the notebook a dialog asking you to enter that code. Once done, the Wi-Di connection is secure and you won't need to enter the code again unless you unplug the Wi-Di adapter from its power source.

Now you're done and ready to enjoy Wireless Display
and your TV should be cloning what the notebook is showing. With the display connected via Wi-Di, it appears like a second monitor
attached to the Windows system and can be configured like any other
secondary display.

The maximum resolution we're able to achieve on the Dell 15z with Wireless Display is 1366x768. 1280x720 is the recommended resolution to maintain a full 30 FPS with media playback.

The Netgear PTV1000 adapter and display appears like any other attached display in Windows 7.
