Hi Kring, I responded to your answer, but it never posted so here is is again. I am totally ignorant of what Google Home app and what Chromecast can do for me. I looked for some information on , you guessed it, Google concerning Chromecast. There seems to be a number of different selections to pick from, but I just am confused about what I should do. It would be a great help if you could give me some instructions on what to do. Remember that I am in a remote location without any Internet connection with the exception of the ASI AIR Plus WI-FI. I am going to purchase a dongle for Chromecast and I would like to have some information on its setup and how to connect it to the ASI AIR Plus box. However, If my setup is not compatible to the system, I will not get the dongle since it is almost $50.00. My big screen is about 10 years old, but it does have three HDMI plugs. Thanks again for you help. RFB
