(Redirect) Dell Latitude 10 Miracast WDDM 1.3 not working

Dell Latitude 10 Miracast WDDM 1.3 I have two Dell Latitude 10 Tablets and I can not get either to connect to the Netgear Push2TV adapter. They both see it and let you enter the code but then nothing. These tablets came with win 8 and I upgraded them to win 8.1 pro. The charm bar has no way to connect to a device option. It seems that I need WDDM 1.3 which was suppose to come with the 8.1 upgrade but when I look I still have WDDM 1.2 Listed. Dell shows in their video on this tablet that you can connect to this adapter but when I contacted them they just wanted to sell me support services and could not answer my question. Is this function not available for this tablet yet with the 8.1 upgrade or do I need an additional driver or software. I have installed all updates and dell drivers and still can not get it to work.
