Thanks for your question! You will need some additional hardware; specifically, you will need this: http://www.samsung.com/us/mobile/cell-phones-accessories/EAD-T10JDEGSTA
Can I mirror from a SAmsung Galaxy S4 to a Samsung UN55D7000 TV without any additional hardware? Or do I need to buy a all share cast dongle for my TV?
If I use HTC One phone, I understand that I need to buy a MediaLink HD adapter to do this.
So if I can do it for free from Galaxy S4, that is what I will get. I am deciding which phone to upgrade to.
