Apple's Digital AV Adapter compatible with smasung smart tv
My Apple's Digital AV Adapter worked great with my old Sony TV and was able to mirror it with my iPad mini with no issues. I upgraded my TV to a Samsung Smart TV and when I connect the Apple's Digital AV Adapter with the HDMI cable I get an error saying I have to go into settings from my iPad and select screen mirroring to be turned on.
So I guess my question is how do I get my Apple's Digital AV Adapter to work with my Samsung Smart TV?
Thank you
iPad Mini, iOS 9.3.2
