I've seen You Tube Video's where people "claim" to have a stalker app for Smart TV. But I have yet to hear of anyone actually using one. Maybe someone who has knowledge can step forward.
I have a Samsung Smart TV and I bought an AVOV STB then connected it to one of the HDMI port and it all works for me.All I have to do is select the number of the HDMI port corresponding with the AVOV connection at the back of the TV.Works for me.
