also this was a response in another thread that I read regarding the Killer Wireless Cards:
Hi Eddie,
I got some clarification on this for you. Actually the Killer Wireless-N Cards don't have anything to do with a laptop being able to stream wirelessly to a TV or other source.
To be able to stream wirelessly depends most on the graphics card. Intel makes integrated graphics cards that are in some of our systems, but never in any Alienware systems. Alienware, since it's more about the graphics and power for gaming, had a dedicated graphics card. Those can do what's called wireless HD.
For that technology, customers can buy a box to plug their TV (or projector) into (i.e. a receiver), and a USB device to stream wirelessly to that TV. Some of our Alienware's offer the option to build in that wireless HD, so the customer would only need to purchase the box to go on the receiving end.
Does that help?
Thanks,
Emily
In my case i have Intel Graphics 4600 along with my other video cards.
