Another confirmation... I have a Dell XPS 2710 all-in-one. I also get the message from DirecTV2PC regarding the screen capture issue. I have just updated the driver from Dell's site, but have not restarted. I'll check again once I do that, but I am doubtful it will make a difference based on the information in this thread. Also, my system is showing the connector type is EDP.
Also, a big thanks to Intel for actually responding on the thread with updates. It sucks that it isn't working, but it's awesome commitment to the customers (at least so far... so keep it up please).
