Chromecast
Phone or computer onto the TV.
1. Get Google TV Streamer
$99. Replaces the older Chromecast. Plugs into HDMI on the TV.
2. Set up
Free Google Home app. Walk through setup. Connect to home Wi-Fi.
3. Cast YouTube
Open YouTube on phone. Tap the cast button (square with curves). Pick your TV.
4. Cast Netflix and more
Same idea. Most streaming apps support cast — Hulu, Prime, Disney+.
5. Voice control
With Google Home, say Hey Google, play news on the bedroom TV.
6. Mirror screen
Show family photos from phone on the big TV. Great for visits.
Apple users — pick Apple TV ($129) instead. Better for AirPlay from iPhone and iPad.
