OMG. Before giving the "standard and totally unrelated advice" please do a little research about the product. Did you even read the OP? Did you see that the software cannot even be successfully installed? Kiran-K, your response frankly is insulting in that you clearly either didn't even really read the stated problem, or you don't understand how the process even works.
I guess this answers my first question. I still have yet to learn of a single, solitary XPS12 that has run WiDi. At this point, I would prefer that Dell support NOT respond to this thread. Frankly, I've spend hours with Dell support and various Dell resources. None of them have been in the least bit knowledgeable about this area, and frankly have not delivered any results whatsoever. The system is behaving exactly the same right now as it has from the start. Neither can Dell show me a single instance where they have been successful with this specific model. I'm more interested in hearing from other customers. Most important to me would be XPS12 owners, though feedback from any current XPS model owner would be relevant.
