Don't have an iPad2 yet, can't find one for sale. Bought the new HDMI connector and attached it on my original iPad. Connect to my LG HDTV, when you start the sling app, it does not show up on the iPad but instead plays nice and wide on the TV screen. Very cool.
So far, very few apps are working; seems only the Apple apps (Ipod, Youtube, Photos) will play both video and audio. Other apps like CNN, Hulu+, ABC, Engadget....only the audio comes thru.
