OK, been playing with it more and I am able to get the photos to appear on the TV somewhat regularly. No luck with the video.
I have a Samsung TV (2013 model, ES7100) and I haven't gotten Screen Mirroring to work.
Have you had any more luck? Is there a particular app that you run on your TV before you start trying to mirror from the phone? I can't seem to get the phone to even "see" the TV from the "Screen Mirroring" tool.
Any help is greatly appreciated!
