As I understand it, the Large Format Displays are nothing more than extra large computer monitors. There is no way to get it to act as a tv all by itself. Looking at Newegg, I came across this Samsung 50" LFD
. It appears there is an "optional set back box" that would allow this particular device to act as a normal TV. Whether or not your TV is capable of this, I don't know, but it's something you may want to look into.
