David can't see his Google Home device and his Chromecast on his wifi network. Leo says if you're on the same network, and can see both, you should be able to see them. But Google Home uses Bluetooth to signal its presence online, so you have to turn on Bluetooth in order to see it, along with WiFi. You don't have to join it, but you do have to turn it on. You also have to look for Load Media Router Component Extension. Here's a how to, from ScooterX.
WD would like to cut the cord, but he doesn't want to pay extra for the internet as well. Leo says that's what ISPs will do. If he has a cable provider also handling internet access, they'll just make up for the cord-cutting by jacking up the rate on internet access. Can he cast to his SmartTV and just use his mobile data plan? Leo says it depends on what his cellular carrier provides. Most will have data caps, but if he doesn't do it all the time, he can "cast" it. It's called DNLA, or Miracast. Samsung can do it if both TV and mobile phone are Samsung. It's called SmartView.
Steven is suddenly getting a warning on his TV that his Roku Stick is getting too warm and could shut down. He unplugged it and cooled it down, and has now added an extender to keep its distance. Leo says that he stopped using the Roku stick because they tend to overheat and crash. It's the same with the FireTV Stick and others. They overheat normally, and that's not good for electronics. Using an extender is a good idea, but Leo prefers using the stand-alone Roku Ultra 4K box. If you like a stick though, the Google Chromecast is the way to go.
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.
Gary watches live sports on the Peacock app, casting to his TV from the Chromecast. But he wants to be able to do it on his boat. Leo says you need WiFi to do that, as both devices have to be on the same network. He also hears he can create his own wifi using a router and connecting to an antenna on the hill. Leo says it's probably a hotspot that will enable you to connect to it.
Jessica is trying to teach some students at home and some in the classroom at the same time. What she's been doing is treating all students as being at home, so they are all logged into Google Meetings. But the problem is, that kids keep forgetting to mute their mics and the feedback is driving her crazy. She would also like to project all the home kids onto the screen so the kids in the classroom can see them.
Ken is having issues casting from his mobile phone via Chromecast to his LG TV. He has a Google Pixel 4a. Leo says it's probably that his Chromecast is too old. So it sounds like Ken would need a new version. The good news is, they're pretty cheap.
Rick cut the cord about a year ago and he streams using YouTube TV. Leo uses it too, but at $50, you're not really saving anything. Especially when you spend money on HBO, Netflix, etc. But their DVR capability is great.
Michael uses a Chromebook in the garage for working out. But the video is rather janky. So he added a Chromecast and a video monitor. The Video is improved, but he doesn't want separate audio output. Leo says the HDMI carries both audio and video, but you can split it into a stereo. Leo adds though, that it can be tricky because you'd need a powered speaker to do it. Michael is currently using a headphone jack connected to computer speakers. Not really optimal.
G. Scott has a friend who has Chromecast and a Chromebook. But he can't control the volume because he doesn't have a smartphone to do it. Is there a way around it? Leo says that volume control is a new feature in Chromecast, so if his Chromebook is an older model, it may not support it.
