@pompeyboy I think it depends what apps you are using on your A7 that you want on your TV. My 2017 Smart LG TV let's me watch both locally stored and some streamed from the Internet video content wirelessly using my Tab A (2018 10.5). Its normally just a case of tapping and holding down on the screen until the icon to do this appears along with details of my TV that I want it playing back on.
