So inside my Alienware 14 is a DMC slot which as I understand it an mPCIE slot. I've seen mention in a few places of a wireless video option (I think intel) that is installed here in some cases. I remember them mentioning a card AND a cable that have to be installed. I THINK I've found the card on ebay, and I THINK I've found the cable but nothing telling me they are correct and work together OR that they work with this laptop. Does anyone have any additional information on what parts are needed, how to install? What do I need on the other side to connect to my monitor?

Once in place is this arrangement worth it? Does it perform well? Is it crummy?

Thank you!
