Steve wants to use TV screens to create a large screen photo gallery in his home. Leo says he could use a Chromecast or Apple TV for each TV screen and stream photos from Google Photos. He would also want to join all screens together for one big picture. Leo says that could be a bigger challenge because each TV has to join with the other. A Raspberry Pi could perhaps do it, but you'd have to write custom code to be able to create a Video Wall Mosaic.
Mike bought a Lenovo Smart Display for his mother, but they're having trouble linking her feature phone to the display. Leo recommends creating a Google account for his mother, then use the app to sign into it. You can also get a cheap or used phone that can connect to WiFi. Set it all up and connect to her WiFi. Have only one icon on it for Google Home, and that should connect her. Also, check out the Google Home Hub Max.
