With the S4 it has now worked out, the picture and sound are really good. There is a slight delay, but does not bother to look for movies or pictures. In games, which is probably a bit annoying depending on the game. But what annoys me more is the fact that neither PC nor laptop work with it. Is with me on the HW. Under Windows (7) should be pre-test times, if you can install WiDi. If this is not the case, then the HW is not compatible and it will not work. Since I have however bought the part of the connection from the mobile phone, do not bother me.
