Take it with you wanting to stick to a wired connection you are looking at playing games ?
If not Mira-cast is an awesome little party trick !
I use mine with my LG smart TV its brilliant !! There is maybe a slight delay for gaming but tbh thats why i bought a PS....however HD movies seem to work fine as it adjusts for the sync to work !
I also use mine as a jukebox at times pretty nifty.
Goodluck with either the cable or dongle you decide to go with, let us all know how you get on
